SAFETY TRAINING INFORMATION  
SAFETY TRAINING INFORMATION  
WARNING  
This radio produces RF electromagnetic energy when transmitting and is  
designed and classified for “Occupational Use Only”. Radio equipment  
with this classification must be used only during the course of employ-  
ment by individuals aware of the hazards and the ways to minimize such  
hazards. This radio is NOT intended for use by the General Population in  
an uncontrolled environment.  
This radio has been tested and complies with FCC RF exposure limits for  
“Occupational Use Only”. In addition, it complies with the following  
standards and guidelines with regard to RF energy and electromagnetic  
energy levels and evaluation of such levels for exposure to humans:  
• FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating  
Compliance with FCC Guidelines for Human Exposure to Radio  
Frequency Electromagnetic Fields.  
• American National Standards Institute (C95.1-1992), IEEE Standard  
for Safety Levels with Respect to Human Exposure to Radio  
Frequency Electromagnetic Fields, 3 kHz to 300 GHz.  
• American National Standards Institute (C95.3 -1992), IEEE Recom-  
mended Practice for the Measurement of Potentially Hazardous  
Electromagnetic Fields - RF and Microwave.  
CAUTION  
To ensure that your exposure to RF electromagnetic energy is within the FCC  
allowable limits for occupational use, always adhere to the following guidelines:  
• DO NOT operate the radio without the proper antenna attached. This may  
damage the radio and cause FCC RF exposure limits to be exceeded. The  
proper antenna is the antenna supplied with the radio by the manufacturer  
or an antenna specifically authorized by the manufacturer for use with this  
radio.

SAFETY TRAINING INFORMATION  
• DO NOT transmit more than 50% of total radio use time (50% duty cycle).  
Transmitting for more than 50% of the time can cause FCC RF exposure  
compliance requirements to be exceeded. This radio is transmitting when-  
ever Tx is indicated in the lower right corner of the display. Pressing the  
PTT switch on the side usually causes the radio to transmit.  
• DO NOT use any accessories not specifically authorized by the E.F.  
Johnson Company for use with this radio such as batteries, speaker-  
microphones, belt clips, and antennas. The use of unauthorized accessories  
can cause FCC RF exposure compliance requirements to be exceeded.  
• ALWAYS keep the antenna and radio at least 2.54 cm (1.0 inch) away from  
your body when transmitting to ensure FCC RF exposure compliance  
requirements are not exceeded. The best transmission quality results when  
the antenna is at least 5 cm (2 inches) away from your mouth and angled  
slightly to one side.  
• This unit has not been tested for FCC RF exposure compliance in applica-  
tions where the unit is transmitting while body worn on the belt clip. This  
product is not intended for use in applications where transmissions are  
required while the unit is body worn with the use of the belt clip.  
NOTE: The preceding information is provided to make you aware of RF expo-  
sure and what to do to ensure that this radio is operated within FCC RF  
exposure limits.  
Electromagnetic Interference/Usage Compatibility  
This device complies with Part 15 of the FCC rules. Operation is subject to the  
condition that this device does not cause harmful interference. In addition,  
changes or modification to this equipment not expressly approved by the E.F.  
Johnson Company could void the user’s authority to operate this equipment  
(FCC Rules, 47CFR Part 15.19).  
DO NOT operate it in areas that are sensitive to RF energy such as aircraft,  
hospitals, blasting sites, and fuel storage sites. Areas with potentially flammable  
atmospheres are usually, but not always, clearly posted. These may include gas  
stations, fuel and chemical storage and transfer stations, below deck on boats,  
and areas where the air contains flammable chemicals or particles such as grain  
dust or metal powders.  
Dispose of the nickel metal-hydride battery used by this radio in accordance with  
local regulations. DO NOT dispose of it in fire because it can explode. Also, do  
not short the terminals because it may become very hot.

BASIC OPERATION  
BASIC OPERATION  
Power-Up Sequence  
When power is turned on using the top panel on-off/volume control,  
the backlight turns on, all segments and icons in the display are momen-  
tarily enabled, and the last seven digits of the transceiver part number are  
very briefly displayed. A beep then sounds (if tones are enabled) and the  
transceiver is operational.  
Backlight Operation  
The display and keypad backlight automatically turns on for 3  
seconds whenever power is turned on or any key is pressed. If the Back-  
light menu parameter is available (see page 35), selecting “On” enables  
this operation and selecting “Off” disables the backlight entirely.  
Setting Volume Levels  
The relative volume level can be determined by noting the position  
of the index on the volume knob. You may also be able to enable a tone  
or background noise for use in setting the volume as follows:  
• If key press tones are enabled, a short tone sounds whenever any key is  
pressed.  
• If a conventional system is selected and the monitor option switch is  
programmed (see page 49), press this switch and if someone is talking  
on the channel, voice is heard. If no one is talking, the squelch can be  
adjusted as described on page 48 and noise is heard. It is not possible to  
manually unsquelch the transceiver when an LTR-Net or LTR system  
is selected.  
System/Group Display Mode  
Two system/group display modes can be selected. One is a numeric  
format and the other is an alpha tag format. To switch between these

BASIC OPERATION  
modes, press FCN STR. Turning power off does not change the selected  
mode. These modes operate as follows:  
Numeric Mode - The system and group numbers are displayed as “Sxx  
Gxx” and the group alpha tag is not displayed. For example, System 1  
and Group 2 are displayed as follows. When only group scanning is  
occurring, the group number is replaced by dashes and the system  
number continues to be displayed (see page 40).  
Numeric Display Mode  
Alpha Tag Mode - The group alpha tag is displayed and the system and  
group numbers are not displayed. For example, the “CAR 220” system is  
displayed as follows. There is no special group scan indication when only  
group scanning is occurring.  
Alpha Tag Display Mode  
System and Group Select  
Systems and groups are selected by the keypad SYS and GRP keys  
and one or more other keys as follows:  
• To increase the selected system, press SYS and then  
. Likewise, to  
increase the selected group, press GRP . Holding the key down  
causes the function to repeat. After the highest system or group is  
selected, a tone sounds and wrap-around to the lowest system or group  
occurs.  
• To decrease the selected system, press SYS and then  
. Likewise, to  
decrease the selected group, press GRP . Holding the key down  
causes the function to repeat. After the lowest system or group is  
21

BASIC OPERATION  
selected, a tone sounds and wrap-around to the highest system or group  
occurs.  
• To directly select a system or group number, press SYS or GRP and  
then the number of the desired system or group. For example, to select  
Group 9, press GRP, 0, 9. A leading “0” must be entered for digits 1-9  
for the selected system or group to change.  
Keypad Disable  
Occasionally, the front panel keys may be accidentally pressed, for  
example, if you carry the transceiver on your belt and it brushes against  
an object. To prevent this from happening, the front panel keys can be  
disabled. To disable and enable the keypad, press FCN  
. The locked  
condition is indicated by the icon. If a key is pressed with the keypad  
locked, all that happens is “LOCKED” is displayed. The top and side  
panel controls remain functional with this feature selected. Turning the  
power off and then on again does not unlock the keypad.  
Transceiver Lock  
The transceiver can be locked to prevent unauthorized usage. To  
lock the transceiver, press FCN  
and “PASSWORD” is then displayed  
to indicate that a four-digit unlock password must be entered. This pass-  
word can be any four-digit number except “0000”. The password must be  
re-entered to confirm it and the transceiver is then locked as indicated by  
“LOCKED” in the display. To unlock the transceiver, the four-digit pass-  
word is re-entered.  
When the transceiver is in the lock mode, calls cannot be received or  
transmitted. In addition, all controls except the on-off/volume control are  
disabled. The transceiver then remains unlocked until it is locked again  
by repeating this sequence.  
Since the password is not preprogrammed, a different password can  
be entered each time this feature is used. If the password is forgotten, the  
transceiver must be returned to your system operator for reprogramming  
to make it operational again.

BASIC OPERATION  
Low Battery Indication  
When the battery voltage drops to the point where recharging is  
required, the  
icon is indicated in the bottom part of the display.  
In addition, a beep sounds when this indication initially appears and when  
the push-to-talk switch is released (if the key press tone is enabled). The  
battery should be recharged as soon as possible after this indication  
appears (see page 57).  
Current settings of switches and other parameters are saved in  
memory during a low-battery condition, and low transmit power is auto-  
matically selected (indicated by “L” in display). The low-battery indica-  
tion is cleared by turning power off and then on again.  
Option Switches  
This transceiver has three option switches that can be programmed  
by your system operator to control the monitor function and most func-  
tions that are selectable by the front panel keys (see table on page 34).  
The option switches are the push-button switch on the top panel and the  
switch immediately above and the switch immediately below the PTT  
switch on the side panel (see page 12).  
LTR-Net, LTR, and Conventional Operation  
Introduction  
Each selectable system can be programmed for LTR-Net, LTR, or  
conventional operation. The type of operation that is programmed is  
determined by the radio equipment being used by your system operator.  
There are a few differences in operation that are described in the  
following information and also noted elsewhere in this manual as  
required.  
23  
Download from Www.Somanuals.com. All Manuals Search And Download.  
       
BASIC OPERATION  
LTR-Net and LTR Operation  
The LTR-Net and LTR modes provide automatic channel selection  
and monitoring before transmitting. Special tones and display messages  
indicate busy and out-of-range conditions, and telephone calls can be  
placed almost as conveniently as with your home telephone.  
Selecting a system selects a collection of up to 99 groups. Selecting  
one of these groups selects an ID code which determines the type of call  
(standard group, telephone, or special), the specific mobile or mobiles is  
being called (if applicable), and what calls are received. In addition,  
higher priority calls may be received (see page 45).  
The LTR-Net operating mode provides the most operating features.  
Exclusive LTR-Net features include roaming and Unique ID and Directed  
Group calls. When operating in LTR-Net sites, calls may be made to  
mobiles in other sites as well as the current site. LTR-Net and LTR  
features are described starting on page 45.  
Conventional Operation  
In the conventional mode, selecting a system selects a conventional  
channel, and selecting a group selects the special Call Guard squelch  
coding (if used) and other unique parameters on that channel such as call  
indicator operation. The Call Guard coding determines the mobile or group  
of mobiles being called and also the mobiles from which calls are received  
(see “Call Guard Squelch” on page 51).  
In the conventional mode, a busy condition is detected automatically  
if the Transmit Disable On Busy feature is used. Otherwise, it must be  
detected manually as described in “Monitoring Before Transmitting” on  
page 49. Unsuccessful access conditions cannot be detected with conven-  
tional signaling, so are not indicated by special tones or display  
messages. Refer to “Operation At Extended Range” on page 60 for infor-  
mation on how to determine if an out-of-range condition may exist.

GENERAL FEATURES  
GENERAL FEATURES  
Bank Select  
A bank is a collection of selectable systems that have been set up for  
a specific application. For example, one bank could be programmed for  
operation in Minneapolis and another for operation in Milwaukee. Up to  
sixteen banks can be programmed, and each bank is identified by a  
unique alpha tag.  
Banks are selected by the BANK SEL menu parameter. In the menu  
mode select the “BANK SEL” parameter and then the desired bank (refer  
to page 35 for more menu mode information). If this menu parameter is  
not available, banks are not selectable.  
Call Indicator  
The call indicator is “C” in the upper part of the display (see  
following illustration). The purpose of this indication is to show that a  
call was received while you were away from the radio. Individual groups  
can be programmed for this feature and it then turns on when a call is  
received on one of those groups.  
Call  
Indicator  
C
This indicator is turned off by pressing any button or cycling power.  
If scanning and the “Last Received” configuration is programmed (see  
“Transmitting In The Scan Mode” on page 43), the system and group of  
the last call are displayed. Otherwise, the currently selected system/group  
is displayed.

GENERAL FEATURES  
Home System/Group Select  
To select the preprogrammed Home system/group, simply press the  
FCN HOME. The Home system/group programmed for the current bank  
is then displayed and it becomes the selected system/group. If no home  
system/group has been programmed, this function is not available.  
Proceed (Clear-To-Talk) Tone  
This is a short tone that sounds shortly after the PTT switch is  
pressed to indicate that the radio system has been accessed and speaking  
can begin. This tone can be programmed to be a single or distinctive (3-  
beep) tone. With encrypted calls, a special double beep sounds.  
This tone always sounds with LTR-Net and LTR standard calls if  
tones are enabled by the TONES menu parameter (see “Tone Select” on  
page 27) or system operator programming. It can also be programmed to  
sound with conventional calls and/or LTR-Net and LTR auxiliary and  
telephone calls (first access only).  
On LTR-Net and LTR systems, if the radio system is busy when  
making a call, the busy tone sounds instead of the proceed tone and  
“BUSY” is indicated in the display. If an access attempt is unsuccessful,  
such as because of an out-of-range condition, the intercept tone sounds  
and “NO ACESS” is indicated in the display. Refer to page 52 for more  
information on these conditions.  
If the proceed tone is enabled on conventional systems and the  
Transmit Disable On Busy feature is used to automatically perform moni-  
toring (see page 50), the proceed tone does not sound if the channel is  
busy. Otherwise, it sounds even if the channel is busy.  
Receive-Only Groups  
Any group can be programmed for monitoring only (transmitting  
disabled). If the PTT switch is pressed with one of these groups selected,  
the intercept tone sounds and “TX DISBL” is displayed.

STANDARD GROUP CALLS  
Time-Out Timer  
The time-out timer disables the transmitter if it is keyed continu-  
ously for longer than the programmed time. It can be programmed for  
0.5 - 5.0 minutes or disabled entirely. If the transmitter is keyed continu-  
ously for longer than the programmed time, the transmitter is disabled,  
“TIMEOUT” is indicated in the display and the intercept tone sounds.  
The timer and tone are reset by releasing the PTT switch.  
One use of the time-out timer feature is to prevent a repeater from  
being kept busy for an extended period by an accidentally keyed trans-  
mitter. It can also prevent possible damage to the transmitter caused by  
transmitting for an excessively long period.  
Tone Select  
If the TONES menu parameter is selectable, the tones that sound can  
be selected. Otherwise, the tones that sound are fixed by programming.  
The following choices are available. Refer to page 35 for more informa-  
tion on using the menu mode.  
Silent - All tones are disabled.  
Keys - Only the key press tones are enabled.  
Alerts - All tones except the preceding key press tones are enabled.  
All - Both the key press and alert tones are enabled.  
STANDARD GROUP CALLS  
General  
Most calls you make are probably the standard group type described  
in this section. These calls are between you and another mobile or control  
station. The main difference between these calls and the other types is  
that no number needs to be dialed. The following procedure applies to all  
three types of operation (LTR-Net, LTR, and conventional).

STANDARD GROUP CALLS  
Placing a Standard Group Call  
1. Turn transceiver power on and set the volume as described starting on  
page 20. With conventional operation, also make sure that the squelch  
is properly set as described on page 48.  
2. Select the system and group of the mobile being called as described on  
page 21.  
3. If a conventional call is being placed, monitor the channel manually or  
automatically as described on page 49.  
4. Press (and hold) the microphone PTT (push-to-talk) switch to talk and  
release it to listen. Operation with LTR-Net, LTR, and conventional  
calls is as follows:  
LTR-Net and LTR Operation  
• If tones are enabled, the proceed tone sounds shortly after the PTT  
switch is pressed if the radio system was successfully accessed (see  
page 26). If tones are not enabled, no tone sounds when the system  
is successfully accessed.  
• If the radio system is busy, the busy tone sounds (see page 52) and  
“BUSY” is indicated in the display. Additional access attempts  
continue as long as the PTT switch is pressed.

STANDARD GROUP CALLS  
• If the radio system could not be accessed because of an out-of-range  
condition or some other reason, the intercept tone sounds (see  
page 52) and “NO ACESS” is indicated in the display. The PTT  
switch must then be released and pressed again to make another  
access attempt.  
• When responding, busy or no access conditions may also occur, the  
same as when placing a call because the radio system is re-accessed  
for each transmission with these calls.  
Conventional Operation  
• If the channel is busy and the Transmit Disable On Busy feature is  
programmed (see page 50), “DSBL BSY” is indicated in the display  
and the transmitter is disabled. Any channel activity is heard while  
the PTT switch is pressed.  
• Otherwise, busy and out-of-range conditions are not indicated and  
speaking can begin when the PTT switch is pressed (if the channel is  
not busy). If the proceed tone is enabled on conventional systems, it  
indicates when speaking can begin but does not indicate that the  
channel is free or has been successfully accessed.  
Receiving a Standard Group Call  
1. Select or scan the system and group programmed for the call you want  
to receive (see page 40 for scan information).  
2. When the message is received, the display changes to the system and  
group of the call. Press the PTT switch to talk and release it to listen. If  
scanning, a response may not automatically occur on the group of the  
call. Refer to “Transmitting In The Scan Mode” on page 43 for more  
information.

TELEPHONE CALLS  
TELEPHONE CALLS  
General  
NOTE: Telephone calls can be placed and received only if that service is  
available to you and your transceiver has been programmed  
appropriately.  
The telephone calling feature allows you to place and receive tele-  
phone calls using your transceiver. The following information describes  
how these calls are made with LTR-Net and LTR operation. If you can  
make telephone calls with conventional operation, the procedure may be  
somewhat different and your system operator may provide additional  
information. Proceed as follows:  
Placing Telephone Calls  
1. Turn transceiver power on and set the volume as described starting on  
page 20.  
2. Select the dial mode and a telephone group as follows. When the dial  
mode is selected, the handset portion  
of the telephone icon is  
displayed, and then when a telephone group is selected, the base portion  
is displayed.  
• To select the dial mode and a preprogrammed telephone group, press  
FCN PHONE.  
• To select the dial mode without changing the selected group, press  
FCN DIAL. Then manually select a telephone group if required.  
3. Dial the desired number using the keypad or recall it from memory by  
pressing FCN RCL and the location number (0-9). Refer to the dial  
mode description starting on page 37 for more information.  
4. To send the telephone number, briefly press the PTT switch to access  
the system and then press FCN SND. Landside ringing (or busy) should  
then be heard. The following conditions may also occur:

TELEPHONE CALLS  
• If the radio system is busy or could not be accessed, busy or no  
access conditions are indicated the same as described for standard  
group calls on page 28.  
• With LTR-Net operation, a short tone sounds to indicate that the  
number was accepted by the system.  
5. When the other party answers, press the PTT switch and respond. The  
PTT switch must be pressed to talk and released to listen (the same as  
with standard group calls).  
6. When the call is finished, it should be terminated and the dial mode  
exited. The call is usually terminated by transmitting either the or  
#
# characters.  
To automatically send these characters and exit the dial mode, press  
FCN PHONE. To exit the dial mode without sending these characters,  
press FCN DIAL. Termination is indicated by three beeps. Terminating  
the call in this manner prevents extra billing that may occur while the  
system automatically detects the end of the call.

LTR-NET AUXILIARY CALLS  
Landside-Originate Telephone Calls  
If telephone calls can be placed, it is usually possible to receive tele-  
phone calls from a landside telephone. With some radio systems, each  
mobile is assigned a unique telephone number so that it can be dialed  
directly. With others, the number of the radio system is dialed and then  
when a tone sounds, the number specifying the mobile being called is  
dialed. The mobile user hears “ringing” when a telephone call is received.  
Contact your system operator for the number to dial and other informa-  
tion on how to place these calls.  
LTR-NET AUXILIARY CALLS  
General  
The LTR-Net auxiliary calls are Unique ID and Directed Group  
calls. Unique ID calls are placed to specific mobiles, and Directed Group  
calls are placed to specific talk groups. These calls can be made to other  
mobiles in your site or some other site that is part of your radio network.  
As with telephone calls, a special number must be dialed to place  
these calls. The number dialed is 1-10 digits long, and is provided by  
your system operator. Other requirements to place these calls are they  
must be authorized on the radio system and your transceiver must be  
properly programmed. Refer to page 46 for more information on LTR-  
Net calls.  
Placing LTR-Net Auxiliary Calls  
1. Turn transceiver power on and set the volume as described starting on  
page 20.  
2. Select the LTR-Net system and group programmed for auxiliary calls.  
When an auxiliary call group is selected, “UID” is indicated in the  
lower part of the display. If the group alpha tag is displayed, it may also  
indicate when one of these groups is selected.

LTR-NET AUXILIARY CALLS  
3. Select the dial mode by pressing FCN DIAL. This mode is indicated  
when the handset portion  
of the telephone icon is displayed.  
4. Dial the desired number which specifies the mobile or group of mobiles  
being called. If it has been previously stored, this number can be  
recalled from memory by pressing FCN RCL and the location number  
(0-9). Refer to the dial mode description starting on page 37 for more  
information.  
5. To send the number, briefly press the PTT switch and then when the dial  
tones sounds, press FCN SND. Another tone then sounds to indicate  
that the call was accepted by the system. The call then proceeds as  
follows. If this tone does not sound, an unauthorized or incorrect  
number may have been dialed. If all system resources are busy, the call  
is placed in a queue as described in “Busy Queuing” on page 46.  
Unique ID Call - Ringing is heard to indicate that the other transceiver  
is being rung. If there is no answer, ringing automatically stops after  
several rings and the call is terminated. When the other party answers,  
respond as with a standard call.  
Directed Group Call - A second tone sounds to indicate that the path  
is complete and speaking should begin. No ringing occurs.  
6. When the call is complete, it should be terminated the same as  
described in step 6 on page 31. Three beeps indicate that the call has  
been terminated.  
Receiving Auxiliary Calls  
To receive a Unique ID call, all that is required is that an LTR-Net  
system is selected that contains a group programmed for those calls. To  
receive a Directed Group call, the group of the call usually needs to be  
selected or scanned. A Unique ID call is indicated by a “ringing” tone  
similar to telephone calls, and a Directed Group call is indicated by the  
caller’s voice the same as with standard group calls.

OPTION SWITCHES AND MENU MODE  
The transceiver may be programmed so responses always occur on  
the last selected group. In this case, the group may need to be manually  
changed to respond to these calls (see “Transmitting In The Scan Mode”  
on page 43). Unique ID and Directed Group calls can also be placed from  
a landside telephone. The same numbers are dialed as when the call is  
mobile originated. Contact your system operator for more information on  
how to place these calls.

DIAL MODE  
DIAL MODE  
Introduction  
When placing calls that require a number be dialed (telephone and  
auxiliary), using the dial mode allows the number to be dialed at any  
convenient rate, dialing errors to be corrected, and then the radio system  
to be automatically accessed and number transmitted when desired. The  
dial mode also allows up to ten 16-digit numbers to be stored in memory  
and later recalled.  
When in the dial mode, the SYS and GRP keys become RCL  
(Recall) and CLR (Clear) keys. Therefore, the selected system and group  
cannot be changed when the dial mode is selected. The information  
which follows describes how the dial mode is used.  
Selecting Dial Mode  
Selecting Dial Mode and Telephone Group - To select the dial mode and a  
telephone group in the current system, press FCN PHONE. If there is more  
than one group programmed for telephone calls in the current system, the  
first high numbered telephone group is selected. If there is no telephone  
group or a conventional system is selected, “NO PHONE” is displayed and  
an error tone sounds.  
Selecting Dial Mode Without Changing Selected Group - To select the dial  
mode without changing the currently selected group, press FCN DIAL.  
This method should be used when placing auxiliary calls because the  
auxiliary call group and not the telephone group must be selected.  
The dial mode is indicated when the handset portion  
of the tele-  
phone icon is displayed. The base portion is displayed when a tele-  
phone group is selected, and “UID” is displayed when an auxiliary call  
group is selected.

DIAL MODE  
Dialing a Number  
Enter the desired number by pressing the 0-9, , and  
keys. Other  
#
dialing functions are as follows:  
• Only the last 8 digits dialed are displayed. To momentarily display  
the upper 8 digits, press FCN  
.
• To erase the last digit, press the CLR key (hold it down to repeat). To  
erase the entire number, press FCN CLR.  
• To enter a pause, press FCN  
(each pause equals one character).  
Sending the Number  
Briefly press the PTT switch to access the radio system. Then to  
send the number in the display, press FCN SND. The keypad remains  
active while in a conversation to allow additional numbers to be dialed.  
Simply press the PTT switch and dial the number. The number in the  
display does not change when a number is dialed in this manner. If you  
want to save the number in the display (see following information), make  
sure you do so before the dial mode is exited.  
Storing Numbers in Memory  
Up to ten 16-digit numbers can be stored in memory and later  
recalled. Proceed as follows to store a number:  
1. Enter the number as described in the preceding “Dialing a Number”  
section.  
2. To store the number, press FCN STR and the memory location from  
0-9.  
3. If there is already a number in the selected location, it is replaced by the  
new number. To clear a memory location, simply store a blank display.

DIAL MODE  
NOTE: The  
character is stored and sent normally (no pause occurs),  
and the character should not be stored because it may terminate the  
#
call when it is sent.  
Recalling Numbers From Memory  
From Specific Location - FCN RCL 0-9 (location number)  
Stored in Next Location - RCL (hold down to repeat). If a number is  
already displayed, the number in the next higher location is indicated; if  
display is blank, the number in location 1 is indicated first.  
Last Number Dialed by Recalling from Memory - FCN RCL  
Last Number Dialed - FCN RCL  
Exiting Dial Mode  
Without Sending Call Termination Characters - To exit the dial mode  
without sending the call termination characters, press FCN DIAL.  
Sending Call Termination Characters - To exit the dial mode and send the  
characters which automatically terminate the call, press FCN PHONE.  
Terminating a call in this manner prevents any additional billing for the  
time required to automatically detect the end of a call.  
Placing Calls Without Selecting Dial Mode  
Telephone and Auxiliary calls can also be placed without selecting  
the dial mode by using the procedure which follows:  
1. Access the radio system by briefly pressing the PTT switch.  
2. When a dial tone is heard, dial the desired number while pressing the  
PTT switch. If too much time elapses between digits, the call is  
automatically terminated.  
NOTE: When receiving telephone or auxiliary calls, the selection of the  
dial mode is optional because it does not enhance operation.

SYSTEM AND GROUP SCANNING  
SYSTEM AND GROUP SCANNING  
General  
Introduction  
The scan feature monitors, in sequence, the systems and/or groups in  
the scan list. When a message is detected that the transceiver is  
programmed to receive, scanning stops and the message is received.  
Shortly after the message is complete, scanning resumes (unless it has  
been disabled). System and group scanning or group scanning only may  
be used (see next page), and the operation of each type is as follows.  
Refer to page 23 for more information on systems and groups.  
System Scanning - Detects calls on all systems in the system scan list.  
If system scanning is not used, calls are detected on only the currently  
selected system.  
Group Scanning - Detects calls on all groups in the group scan list.  
These groups are from the selected system and also from scanned  
systems if system scanning. If group scanning is not used, calls are  
detected on only the selected group. In addition, calls may be detected  
on higher priority LTR-Net and LTR groups (see “Priority Calls” on  
page 45).  
Scan On-Off  
System and/or group scanning are turned on and off by pressing  
FCN SCAN. When either type of scanning is enabled,  
is indicated in  
the display (see following illustration). Then when group scanning is  
actually occurring, dashes are displayed instead of a group number (if the  
numeric display mode described on page 20 is selected). Group scanning  
is not indicated if the alpha display mode is selected, and system scanning  
is never indicated. The monitor mode must be disabled for scanning to  
occur (see page 49).

Scanning Occurring  
Scan Types  
The type of scanning selected is determined by the menu mode SCN  
TYPE parameter (see page 35). If it is not selectable, the scan type is  
fixed by system operator programming. The available scan types are as  
follows.  
SYSTEMS - Both system and group  
GROUPS - Group scanning only  
OFF - Both types disabled (scanning not selectable)  
If the SCN TYPE menu parameter is disabled, the scan type is fixed  
by programming. The selected system and group can be changed while  
scanning using the SYS and GRP keys in the normal manner. Scanning  
resumes shortly after the change is made.  
When a call is received in the scan mode, the display changes to the  
system and group of the call. Programming determines if this change is  
temporary or permanent, and if a response occurs on the system/group of  
the call or the selected system/group. Refer to “Transmitting In The Scan  
Mode” on page 43 for more information.  
LTR-Net Mode Scanning  
When system scanning with an LTR-Net system selected and  
roaming disabled, only the LTR-Net systems in the scan list that access the  
site of the selected system are scanned (any LTR and conventional  
41  
Download from Www.Somanuals.com. All Manuals Search And Download.  
     
SYSTEM AND GROUP SCANNING  
systems are not scanned). If roaming is enabled, registration on other sites  
occurs normally and scanning of LTR-Net systems occurs as just  
described.  
However, if the current LTR-Net site is lost and no other LTR-Net  
site can be located, the LTR and conventional systems in the scan list are  
also scanned. Searching for an LTR-Net site continues and if one is again  
detected, registration on that site occurs and the LTR and conventional  
systems are no longer scanned. This operation can provide uninterrupted  
operation in areas which have not been converted to LTR-Net operation.  
LTR and Conventional Mode Scanning  
When an LTR or conventional system is selected with system scan-  
ning enabled and roaming disabled, scanning is sequential through only  
the LTR and conventional systems in the scan list (LTR-Net systems are  
not scanned). If roaming is enabled, only LTR-Net systems or all three  
system types may be scanned as described in the preceding LTR-Net  
description.  
Scan List Programming  
General  
NOTE: The selected (displayed) system and group are always scanned  
even if they have been deleted from the scan list.  
NOTE: Deleting LTR-Net systems from the scan list also deletes them  
from locality searching when roaming, even if scanning is disabled.  
The scan list status of the displayed system is changed by pressing  
FCN S.A/D, and the status of the displayed group is changed by pressing  
FCN G.A/D. The displayed system is in the scan list and scanned  
normally when  
is displayed, and the displayed group is scanned when  
is displayed (see preceding illustration). Deleting a system only  
temporarily deletes the groups associated with that system because when  
a system is added back into the scan list, the original group scan list is  
again active.  
42

SYSTEM AND GROUP SCANNING  
Systems and groups can be deleted from the scan list in the normal  
manner while listening to a message on the system or group by simply  
pressing the S.A/D or G.A/D key. Scanning resumes shortly after the  
system or group is deleted.  
Saving Scan List  
If the menu mode SCN SAVE parameter is available (see page 35),  
you can select if scan list changes are saved. If “On” is selected, changes  
are saved as they are made and the scan list does not change when power is  
turned off. Conversely, if “Off” is selected, they are not saved and the  
default status of all systems and groups is reselected when power is turned  
on. If the menu SCN SAVE parameter is not selectable, the scan list save  
mode is fixed in one of these states.  
Scan Delay and Continue Timers  
When a message is received or transmitted while scanning, there is a  
short delay before scanning resumes. The delay after receiving a call  
prevents another message from being received before a response can be  
made. Likewise, the delay after transmitting a call ensures that you hear a  
response to your call instead of another message occurring on some other  
system or group. Note that scanning does not resume if it has been  
disabled, such as by selecting the monitor mode.  
There is also a scan continue timer that may be programmed. This  
timer controls the maximum time that a call is received before scanning  
resumes. Times up to 60 seconds can be programmed. This prevents scan-  
ning from being delayed for long periods by lengthy calls. If the menu  
SCN CONT parameter is selectable (see page 35), this feature can be  
turned on and off.  
Transmitting In The Scan Mode  
General  
When messages are received while scanning, programming deter-  
mines if the selected system/group does not change, changes permanently  
43  
Download from Www.Somanuals.com. All Manuals Search And Download.  
       
SYSTEM AND GROUP SCANNING  
to the new system/group, or changes temporarily. This in turn affects the  
system/group on which responses occur. The display always indicates the  
system/group on which a call is received, but this may not be the system/  
group on which a response occurs. The three programmable configura-  
tions operate as follows:  
Last Selected - Transmissions always occur on the system/group that  
was selected manually by the SYS and GRP keys or automatically by  
roaming. Therefore, to respond to a message that is not on the selected  
system/group, the selected system/group must be changed using one of  
these methods:  
• Select the system/group of the call manually using the SYS and GRP  
keys.  
• Before scanning resumes, exit the scan mode by pressing FCN SCAN.  
The system/group of the call then becomes the selected system/group  
and it is not necessary to change it manually.  
Last Received - The selected system/group changes to the system/group  
of a call. Therefore, you can always respond to a call without having to  
manually change the system/group. To return to the previously selected  
system/group, it must be manually selected using the SYS and GRP keys.  
Temporary Last Received - The system/group changes to the system/  
group of a call for only the duration of the scan delay period (see  
page 43). Then when the delay expires and scanning resumes (if it is not  
disabled), the selected system/group is again displayed. Therefore, you  
can respond to a call without changing the selected system/group as long  
as you do so before scanning resumes.

LTR-NET AND LTR FEATURES  
LTR-NET AND LTR FEATURES  
Transmit Inhibit  
The Transmit Inhibit feature prevents the transmitter from keying if  
the mobile you are calling is busy with another call. When the transmitter  
is disabled by this feature, the intercept tone sounds and “TX INHIB” is  
displayed (see following illustration). To make another call attempt, the  
PTT switch must be released and pressed again. However, you may want  
to wait a few seconds before making another attempt because a timer  
must time out before another attempt will be successful. A similar  
Transmit Disable On Busy feature is available on conventional systems  
(see page 50).  
Priority Calls  
Each LTR-Net and LTR group is programmed with a receive priority  
number. If a call is detected on a group in the group scan list that has a  
higher priority than the selected group, it is received (even if scanning is  
not enabled). If another call is in progress when the higher priority call is  
detected, the current call is immediately dropped. Some groups, such as  
those used to make telephone calls, may be programmed as not interrupt-  
ible to prevent other calls from interrupting a call in progress.  
The system/group of the priority call is displayed while it is  
received. The programming described on page 43 determines if the  
change is temporary or permanent and if a response occurs on the last  
selected or received system/group.

LTR-NET FEATURES  
LTR-NET FEATURES  
NOTE: Other LTR-Net features are described starting on page 45.  
LTR-Net Standard Calls  
Standard group calls are between two mobiles or between a mobile  
and a control station. To place these calls in the LTR-Net or LTR mode,  
simply select the desired group and press the PTT switch (no number is  
dialed) as described starting on page 27.  
LTR-Net Special Calls  
The LTR-Net Special calls are as follows:  
Telephone  
Unique ID  
Special  
Auxiliary  
Directed Group  
Telephone Calls - These calls allow you to place and receive telephone  
calls using your transceiver. They are described starting on page 30.  
Auxiliary Calls - As shown in the preceding illustration, these calls include  
Unique ID and Directed Group calls. Unique ID calls are to specific  
mobiles, and Directed Group calls are to specific talk groups. Refer to  
page 32 for information on placing and receiving Auxiliary calls.  
Busy Queuing  
If system resources are not available when placing special calls,  
queuing may be provided by the radio system. Standard group calls are  
not queued. When a call is placed in a queue, a voice message informs  
you that this has occurred. Then when resources become available, the  
call is automatically placed and the normal ringing or other tones are  
heard if applicable. If the call cannot be placed in the allotted time, it is  
terminated and another message informs you that this has occurred.

LTR-NET FEATURES  
Roaming  
LTR-Net radio localities (sites) can be linked together to provide  
wide area coverage. Calls can then be automatically routed to your  
current location as you travel from locality to locality. Both standard  
group and special calls may be routed in this manner. If your transceiver  
is programmed for roaming, this feature is utilized as follows:  
1. Enable roaming using the ROAMING menu parameter (see page 34) if  
available. If the menu parameter is not available, roaming is fixed in the  
on or off mode by programming.  
2. If scanning is disabled, an LTR-Net system must be selected. If system  
scanning is enabled, any system can be selected if the LTR-Net systems  
are in the system scan list (see page 42).  
When roaming is enabled as just described and the signal from the  
current locality becomes weak, the transceiver automatically begins  
searching for another locality. While searching is occurring, “LCL  
SRCH” is displayed as shown below. Then when a new locality is  
located, registration occurs and “LCL SRCH” is no longer displayed. The  
displayed system is then the next LTR-Net system programmed with a  
different locality that could be accessed, and the displayed group is  
usually the group that was displayed before roaming occurred.  
NOTE: Deleting LTR-Net systems from the scan list also deletes them  
from locality search when roaming, even if scanning is disabled. There-  
fore, make sure none have been inadvertently deleted (see page 42).

LTR FEATURES  
LTR FEATURES  
NOTE: Other LTR features are described starting on page 45.  
Standard Group Calls  
Standard group calls are between two mobiles or between a mobile  
and a control station. To place these calls in the LTR or LTR-Net mode,  
simply select the desired group and press the PTT switch (no number is  
dialed). The procedure for placing and receiving these calls is described  
starting on page 27.  
Telephone Calls  
Telephone calls allow you to place and receive calls over the public  
telephone system using your transceiver. LTR and LTR-Net telephone  
calls are described starting on page 30.  
CONVENTIONAL FEATURES  
Squelch Adjust  
This function sets the squelch level used for conventional calls.  
Since the squelch level for LTR-Net and LTR calls is preset and cannot be  
changed, this adjustment needs to be made only if you make conventional  
calls (refer to page 23 for more information on operating modes). Proceed  
as follows:  
1. Select a conventional system and a group that is not busy. If the selected  
channel is programmed for Call Guard squelch, press the Monitor  
option switch (if programmed) to enable monitoring (see page 49).  
2. Press FCN SQL to select the squelch adjust mode. The currently  
selected squelch level is then indicated by “SQ xxx” in the display.

CONVENTIONAL FEATURES  
3. Press the  
key until receiver noise is heard and then press  
until  
the noise just mutes. To decrease or increase the selected level in steps  
of 10 (or select the minimum or maximum level if this is not possible),  
press FCN  
or FCN  
, respectively.  
NOTE: Slight readjustment may be required if weak messages are not  
heard or unsquelching occurs when no messages are present.  
4. To exit this mode, press the FCN SQL again. Exiting also occurs auto-  
matically after 2 seconds of no activity.  
5. If both narrow and wide band channels are used, perform this adjust-  
ment for each type because separate settings are maintained.  
Monitoring Before Transmitting  
General  
Regulations require that conventional channels (groups) be moni-  
tored before transmitting to make sure that they are not being used by  
someone else. If you were to transmit when someone else is talking, you  
would probably disrupt their conversation. Proceed as follows to auto-  
matically or manually monitor conventional channels. In the LTR-Net  
and LTR modes, monitoring is always performed automatically.  
Automatic Channel Monitoring  
If the selected group is programmed with the Transmit Disable On  
Busy feature (see page 50), monitoring is performed automatically. If not,  
it must be monitored manually using one of the methods which follow.  
Busy Indicator  
With scanning disabled and the squelch properly adjusted (see  
page 48), note if “BUSY” is indicated in the display (see following illus-  
tration). If it is, a signal is being detected on the selected group (channel)  
and you should not transmit a message until it turns off.

CONVENTIONAL FEATURES  
Busy  
Indicator  
BUSY  
Monitor Mode  
There may be times when the Busy indication is displayed even  
though no one is using the channel. Monitoring should then be performed  
using the monitor mode. This mode is enabled and disabled by pressing  
the Monitor option switch (see page 35), and is indicated by  
in the  
display as shown in the following illustration. When the monitor mode is  
selected, both Call Guard squelch (see page 51) and scanning are disabled  
so that any activity on the group is heard.  
Monitor Mode  
Selected  
A conventional system must be selected to enable monitoring. If the  
Monitor option switch is pressed with an LTR-Net or LTR system  
selected, scanning halts but monitoring is not enabled. If the monitor  
option switch is not programmed, the monitor mode is not selectable and  
monitoring is performed automatically as follows.  
Transmit Disable On Busy  
The Transmit Disable On Busy feature automatically disables the  
transmitter if the selected group (channel) is busy and it has not been  
monitored when the PTT switch is pressed. When the transmitter is  
disabled by this feature, the busy tone sounds briefly and “DSBL BSY” is  
indicated in the display as follows:  
50  
Download from Www.Somanuals.com. All Manuals Search And Download.  
     
CONVENTIONAL FEATURES  
While the PTT switch is pressed, the receiver is enabled so that  
activity on the channel can be monitored. The PTT switch must be  
released and then pressed again to make another call attempt. Occasion-  
ally, a busy condition may be detected even though no one is talking. To  
key the transmitter in this case, release the PTT switch and then immedi-  
ately press it again.  
There is also a programmable option with this feature to allow trans-  
mitting with a busy channel if the correct Call Guard signal is detected.  
The Transmit Disable On Busy feature is enabled or disabled on each  
conventional group by system operator programming. If this feature is  
disabled, the transmitter will key even if the group is busy.  
Talk-Around  
Normally, all transmissions go through a repeater which usually  
increases range because the repeater transmits at a higher power level and  
has a higher antenna. However, this means that if you are out of radio  
range of the repeater, you cannot talk to anyone even if the mobile you  
are calling is only a short distance away. To allow communication if this  
occurs, talk-around groups can be programmed which enable direct  
mobile-to-mobile communication without going through a repeater.  
Talk-around is then automatically enabled by selecting one of these  
groups. There is no special talk-around option switch or indicator.  
However, the group alpha tag on the lower line of the display may be  
used to indicate groups programmed for this feature. Talk-around is not  
available on LTR-Net and LTR systems.  
Call Guard Squelch  
The Call Guard squelch feature eliminates distracting messages  
intended for others using the channel. This is done by using a subaudible  
tone or digital code to control the squelch. This tone or code is unique to a  
user or a group on that channel. It is transmitted with the voice signal but is  
not heard because it is in the subaudible range and attenuated by a filter.  
Call Guard squelch can be programmed on each conventional group. LTR-  
Net and LTR operation uses ID codes to perform a similar function.

Supervisory Tones  
The following tones are heard at various times when operating this  
transceiver. Some or all of these tones may be disabled by the TONES  
menu parameter or programming (see “Tone Select” on page 27).  
Busy Tone  
This tone is similar to the standard telephone busy tone, and it indi-  
cates that the radio system is currently busy. The display also indicates  
“BUSY” while this tone is sounding. Repeated access attempts are made  
while the PTT switch is pressed with this tone sounding. Therefore, it is  
not necessary to release the PTT switch to access the system. This tone  
sounds only with LTR-Net and LTR calls.  
Intercept Tone  
This is a siren-like tone (alternating high and low tones) which  
indicates the following no access and error conditions:  
• No Access - If this tone sounds shortly after pressing the PTT switch  
and “NO ACESS” is displayed, the radio system could not be  
accessed, perhaps because of an out-of-range condition (see “Opera-  
tion At Extended Range” on page 60). Once this tone sounds, no  
more access attempts are made until the PTT switch is released and  
then pressed again. This condition is indicated only with LTR-Net  
and LTR calls.  
• Time-Out Timer - If this tone sounds after the transmitter has been  
keyed for an extended period and “TIMEOUT” is displayed, the  
transmitter has been disabled by the Time-Out Timer feature (see  
page 27).  
• Transmit Inhibit - If this tone sounds as soon as the PTT switch is  
pressed with an LTR-Net or LTR system selected and “TX INHIB”

is displayed, the transmitter has been disabled by the Transmit  
Inhibit feature (see page 45).  
• Receive-Only Group - If this tone sounds when the push-to-talk  
switch is pressed and “TX DISBL” is displayed, the group is receive-  
only (see page 26).  
Proceed (Clear-To-Talk) Tone - This is a short single or double tone  
which sounds after the push-to-talk switch is pressed to indicate when  
talking can begin (see page 26).  
Key Press Tone - This is a short tone that indicates when an option switch  
is pressed.  
Wrap-Around Tone - This is a two-pitch tone that indicates that the highest  
or lowest channel was displayed and that wrap-around has occurred.  
Error Tone - This is a two-pitch tone that indicates that an error condition  
has occurred.  
LTR-Net Special Call Tones  
The following tones are generated by the LTR-Net equipment and  
are heard when making a telephone, unique ID, or directed group special  
call on an LTR-Net system.  
Confirmation Tone - This is a short tone that sounds when the number  
just dialed has been accepted by the system.  
Call Proceed Tone - With LTR-Net directed group calls (see page 32),  
ringing does not occur after the number is dialed. Instead, another short  
tone sounds after the confirmation tone to indicate that the audio path is  
complete and speaking can begin.  
End Call Tone - Three beeps which indicate when the end of the call has  
been detected by the system.

MISCELLANEOUS  
Proceed Dialing Tone - When placing a landside-to-mobile telephone  
call (see page 32), the landside caller may enter a special number which  
specifies the mobile being called. This tone indicates when that number  
should be dialed.  
LTR Telephone Call Tones  
The following tones are generated by LTR interconnect equipment  
and are heard when making LTR telephone calls.  
Reorder Tone - Three beeps which indicate that the call has been termi-  
nated by the system.  
Return Time Warning Tone - Two beeps which indicate that you have  
not transmitted for an extended period. If you do not transmit within 5  
seconds, the call is automatically terminated by the system. The time  
between transmissions is one of the parameters used by the system to  
detect the end of a call when the # character is not sent.  
Conversation Time-Out Tone - Calls are limited to a certain length by  
the system. Thirty seconds before this time is reached, a “tick” begins  
sounding each second. When the 30-second time expires, the call is auto-  
matically terminated by the system.  
Turn-Around Tone - This is a single beep which may be used to indicate  
to the landside party when to respond to your transmission. It sounds  
when you release the PTT switch, and you may partially hear this tone.  
Proceed Tone - This tone consists of two beeps and it tells the landside  
caller when to enter the five-digit number specifying the mobile being  
called. Dialing of this number must be started within 5 sec. of hearing this  
tone, and a tone-type telephone must be used.

Rechargeable Battery Pack  
WARNING  
Do not dispose of the battery pack in fire because it may explode. The  
battery pack contains nickel metal-hydride (NiMH) cells which must be  
disposed of in accordance with local regulations. Do not short the termi-  
nals because the battery may become very hot.  
Battery Life  
With proper care, the nickel metal-hydride (NiMH) battery pack  
used by this transceiver should provide excellent service. When the pack  
no longer holds a charge or provides only a very short operating time, it  
must be replaced with a new unit.  
57

MISCELLANEOUS  
Typical operating time before recharging is required is 7.3 hours.  
This assumes that the transceiver is transmitting at high power 5% of the  
time, receiving and producing audio 5% of the time, and in the standby  
mode (receive with audio muted) 90% of the time. If the low-power mode  
is selected or different times are spent in these modes, operating time  
varies accordingly. The charge of the battery and ambient temperature  
also affect operating time.  
NOTE: Be sure to turn transceiver power off before removing the battery  
pack. Failure to do so may result in current settings not being saved in  
memory.  
Recharging  
Recharging is required when the  
icon is displayed as  
described on page 23. To remove the battery pack from the transceiver for  
recharging (see next section), press the spring-loaded release button on  
the bottom and slide the battery off. A new battery pack must be charged  
before use.  
Battery Care  
One cause of shortened battery life is repeated deep discharge.  
Therefore, it is recommended that the battery be recharged as soon as  
practical after the low-battery indication appears (see preceding informa-  
tion). Do not continue using the transceiver until the battery is completely  
discharged. Another cause of reduced battery life is operation at tempera-  
ture extremes. It is also good practice not to regularly leave a pack in the  
charger for extended periods after it is completely charged.  
It is possible that the pack could develop a characteristic called  
“memory” although these packs are designed to minimize that problem.  
When a pack has this problem, it acts as if it is totally discharged even  
though it has greater capacity. This can be caused by discharging a pack  
only slightly before recharging, charging at too high a temperature, or  
extended storage. If a pack develops this problem, it can usually be  
corrected by performing three discharge/charge cycles.

Battery Charger Operation  
Fast Charge Slot  
Slow Charge Slot  
Fast Charge Slot  
Indicator  
Slow Charge Slot Indicator  
The charger shown above has two slots in which to place a battery.  
The back slot is for fast charging and the front slot is for slow charging.  
Only the battery can be inserted in the fast charge slot and the entire  
transceiver can be inserted in the slow charge slot if desired. Batteries can  
be charged in both slots at the same time. The operation of the two indi-  
cators is described in Table 1.  
Fast Charging - When a battery is placed in the fast charge slot, fast  
charging begins as indicated by a steady red indicator. Then when the  
battery is nearly fully charged, the charger switches to a trickle rate (20-  
40 mA) and the indicator turns green. It continues at this rate until the  
battery is removed from the charger. The temperature must be 0 to +45°  
C (+32 to +113°F) for rapid charging to occur. Approximate charge time  
in this slot for a fully discharged battery is 1.5 hours.  
NOTE: Occasionally, a fully charged condition may be falsely detected  
and the trickle mode entered after only a few minutes of rapid charging.  
To resume normal rapid charging if this occurs, momentarily take the  
battery out of the slot.  
Slow Charging - Batteries placed in the front slot are always charged at  
the slow rate (100-120 mA). The slow charge indicator turns green when

MISCELLANEOUS  
charging is occurring, and charging continues at the slow rate until the  
battery is removed from the charger. Approximate charge time in this slot  
for a fully discharged battery is 20 hours (with transceiver power off if  
applicable). If transceiver power is on, this slot basically maintains the  
charge of the battery.

Speaking Into Microphone  
For best results, hold the speaker grille about 1-2 inches from your  
mouth and speak at a normal conversational level. Do not shout since it  
distorts your voice and does not increase range. Make sure that the PTT  
(push-to-talk) switch is pressed before you begin to speak and released as  
soon as the message is complete.  
Operation At Extended Range  
When approaching the limits of radio range, the other party may not  
be able to hear your transmissions and there may be an increase in back-  
ground noise when messages are received.  
Even though you can hear messages, you may still be out of radio  
range. The reason for this is that the signal being received is normally  
transmitted by a repeater which usually has a much higher power level  
than is produced by your transmitter. Communication may be improved  
by moving to higher ground or away from shielding objects such as tall  
buildings or hills.

INDEX  
Licensing  
A government license is usually required to operate this transceiver  
on the air. Your system operator will normally handle the licensing  
requirements.  
Transceiver Service  
If your transceiver is not operating properly, “OUT-LOCK”, “PROG  
ERR”, “SLEEPING”, or “CALL SVC” may be displayed. It may be  
possible to clear the first two conditions by turning power off and then on  
again to reset the control logic. Also, make sure that the controls are  
properly set and the battery is fully charged. If the transceiver still does  
not operate properly, return it to your system operator for service.  
The “SLEEPING” message indicates the transceiver is temporarily  
disabled as described on page 56. If the CALL SVC message is  
displayed, the transceiver must be returned to your system operator for  
service.  
NOTE: There are no user serviceable components in the transceiver.  
Altering internal adjustments can cause illegal emissions, void the  
warranty, and result in improper operation that can seriously damage the  
transceiver.
