from a wall outlet  
Rear View  
1. Connect the tip of the supplied AC adapter to the DC 12V  
jack at the rear of your scanner.  
2. Plug the AC adapter into your wall outlet.  
You must use a Class 2 power source that supplies 12V  
DC and delivers at least 500mA. Its center tip must be set  
to positive and its plug must fit the scanner’s DC 12V jack.  
Using an adapter that does not meet these specifications  
could damage the scanner or the adapter.  
Notes  
To prevent electric shock, do not use the AC adapter’s  
polarized plug with an extension cord, receptacle, or  
other outlet unless you can fully insert the blades to  
prevent blade exposure.

connecting an external antenna  
The ANT jack on the back of the scanner makes it easy to use  
the scanner with a variety  
of antennas.  
You will need to connect  
an external antenna when  
you mount your scanner  
in the dashboard of your  
vehicle. You may also  
want to connect an external antenna if you use  
your scanner as a base station.  
Your local RadioShack store sells a variety of antennas.  
Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to  
connect an outdoor antenna. For lengths exceeding 50 feet,  
use RG-8 low-loss dielectric coaxial cable. If your coaxial  
cable does not have a BNC connector, you will also need a  
BNC adapter (not supplied).

The Basics  
When deciding on an antenna and its location, consider the  
following:  
• The location of the antenna should be as high as possible.  
• The antenna and antenna cable should be as far as  
possible from sources of electrical noise (appliances,  
other radios, and so on).  
• The antenna should be vertical for the best performance.  
Use extreme caution when installing or removing an  
outdoor antenna. If the antenna starts to fall, let it go!  
It could contact overhead power lines. If the antenna  
touches a power line, touching the antenna, mast, cable,  
or guy wires can cause electrocution and death. Call the  
power company to remove the antenna. Do not attempt  
to do so yourself.  
Note  
connecting an external speaker  
If you mount the scanner in your  
dashboard or if you use it in a  
noisy area, you may want to add  
an external speaker (available at  
your local RadioShack store) to  
improve your ability to hear. Plug  
Connect external  
speaker here  
the speaker cable’s 1/8 inch (3.5  
mm) plug into your scanner’s  
EXT SP jack.  
Connecting an external speaker disconnects the  
scanner’s internal speaker.

The Basics  
Listening Safely  
To protect your hearing, follow these guidelines:  
• Do not connect an earphone or headphones to the  
scanner. The warning alert volume is not adjustable, and  
damage to your hearing might result if a warning alert  
sounds while an earphone or headphones is connected.  
• Do not listen at extremely high volume levels. Extended  
high-volume listening can lead to permanent hearing loss.  
• Set the volume to the lowest setting before you begin  
listening. After you begin listening, adjust the volume to a  
comfortable level.  
• Once you set the volume, do not increase it. Over time,  
your ears adapt to the volume level, so a volume level  
that does not cause discomfort might still damage your  
hearing.

The Basics  
step 4: set up your scanner  
turn on your scanner  
Turn VOL clockwise. The scanner turns on and the ALERT  
indicator lights for a moment. Then the alert tone beeps and  
TEST appears. The last setting you selected before turning  
the scanner off appears.  
The alert tone depends on the currently selected setting  
see “Setting the Alert Tone Volume”).  
Note  
set the squelch  
Think of squelch as a gate. If the gate is too low (squelch too  
low), everything (all noise as well as signals) gets through.  
If the gate is set too high (squelch too high), nothing gets  
through. If the gate is set just right (the squelch is set  
properly), just the desired signals get through.  
1. To set the squelch, press HOLD/RESUME to stop  
scanning. HOLD appears. If needed, adjust VOL until you  
do not hear a signal.  
2. Turn SQL fully counterclockwise until you hear a hissing  
sound. This lowers the “squelch gate,” allowing all signals  
and noise to get through.  
3. Turn SQL clockwise just until the hiss stops. This raises  
the “squelch gate,” allowing only strong signals to get  
through. In a city, you may want to adjust the squelch  
even further clockwise to decrease the range of the  
highway warning alert signal. This prevents the alert from  
sounding unnecessarily due to farther, less important  
sources.

The Basics  
listen to preprogrammed frequencies  
Your scanner comes preprogrammed from the factory  
with 150 of the most frequently used frequencies stored in  
Channels 1 to 150 of the private bank. You can scan these  
frequencies as soon as you turn on the scanner.  
common scanner terms  
To nd a station, you must tune to a FREQUENCY (expressed  
in kHz or MHz). To nd active frequencies, use the search  
function or purchase a frequency reference.  
In addition to searching a selected frequency range, you can  
also search your scanner’s service banks. A SERVICE BANK  
is a preset groups of frequencies categorized by the type  
of services that use those frequencies. Your scanner comes  
preprogrammed with all the frequencies allocated to the  
weather, marine, aircraft, rail road, CB, news, and police/fire/  
emergency services.  
When you search and find a desired frequency, you can  
store it into a PROGRAMMABLE MEMORY LOCATION called  
a CHANNEL. Channels are grouped into channel-storage  
banks called a private bank. Your scanner has 10 CHANNEL  
STORAGE BANKS and each bank has 100 channels. You can  
scan the channel-storage banks to see if there is activity on  
the frequencies stored in them.  
scanning overview  
You can scan in one of four ways:  
1. Highway Patrol/Local Police Scanning -- when you select  
a state you want to scan in highway patrol/local police  
mode, you can scan preprogrammed highway patrol/local  
police frequencies.  
18  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The Basics  
2. Service Scanning -- press FUNC + SVC to select one of  
the service banks to find an active frequency.  
3. Band Search -- select a frequency band to search. The  
search function is different from scanning. It searches for  
any active frequency step by step within the lower and  
upper limits of the band. When an active frequency is  
found, the scanner will stop and stay on that frequency  
as long as that transmission lasts. If that frequency is  
interesting to you, press HOLD/RESUME to hold the  
frequency on the display. Then program it into the private  
bank you want to store. If you do not want to program  
that frequency, press HOLD/RESUME or just wait until the  
transmission ends. The search resumes automatically 2  
seconds after the last transmission and looks for more  
active frequencies.  
4. Private Scanning -- the private bank is where you  
program frequencies you want to store into channels.  
Press PVT to scan frequencies you have programmed in  
this bank.  
To program frequencies, see “Storing Known Frequencies  
into Channels”. When scanning stops on an active frequency,  
it remains on that channel as long as the transmission  
continues. When the transmission ends, the scanner will  
remain on the same channel for 2 more seconds, waiting for  
a responding transmission. If no responding transmission  
occurs within 2 seconds, the scanning cycle resumes.

Beyond the Basics  
advanced scanner features  
In this section of the user’s guide, you will discover the  
wide variety of features that make your scanner flexible and  
powerful. As you master these features, you will enhance the  
value and enjoyment of owning your scanner.  
channel storage banks  
To make it easier to identify and select the channels you want  
to listen to, you can assign channels to up to 10 channel-  
storage banks. Each bank has 100 channels. Use each  
channel-storage bank to group frequencies, such as those for  
the police department, fire department, ambulance services,  
or aircraft. For example, the police department might use  
four frequencies in your town while the fire department  
uses an additional four. You could program the four police  
frequencies starting with Channel 1 (the first channel in bank  
1), and program the fire department frequencies starting with  
Channel 101 (the first channel in bank 2).  
storing known frequencies into channels  
You can locate and store specific frequencies into channels  
for later use. Frequencies are widely available on the  
Internet and from the FCC. To assist you in locating a desired  
frequency from the scanner’s wide range, consider using a  
frequency guide. Excellent references for active frequencies  
are the RadioShack Police Call Guide, including Fire and  
Emergency Services, and the Official Aeronautical Frequency  
Directory. We update these directories every year, so be sure  
to get a current copy.  
Follow these steps to store frequencies into channels.  
1. Press FUNC + PGM. PRIVATE and PGM appear.

2. Enter the channel number where you want to store  
a frequency and press HOLD/RESUME to select the  
channel.  
3. Enter the frequency you want to store by using the  
keypad and ./CLR.  
4. Press E to store the frequency into the channel.  
5. To store the next channel in sequence, press e and repeat  
Steps 3 and 4.  
To clear a mistake while entering the frequency,  
Notes  
epeatedly press ./CLR until the display is cleared.  
If you enter an invalid frequency, an error tone  
sounds and Error appears. To clear the error message  
immediately, press ./CLR.  
Your scanner automatically rounds the entered number  
to the nearest valid frequency. For example, if you enter  
151.473 (MHz), your scanner accepts it as 151.475.  
When you enter a frequency into a channel, your scanner  
automatically turns on the delay function and DLY  
appears on the display. When delay is turned on, the  
scanner automatically pauses scanning 2 seconds after  
the end of a transmission before scanning proceeds to  
the next channel. To turn delay off or on, press DELAY.  
If you enter a frequency that has already been entered  
elsewhere, the scanner sounds an error tone and  
displays the channel that was duplicated. If you entered  
the frequency by mistake, press ./CLR, then enter the  
correct frequency. To enter the frequency anyway, press E  
to accept.

scanning a private bank  
You can program frequencies into channels of the private  
bank. There are 1000 channels in the bank. 150 of the  
most frequently used frequencies are preprogrammed into  
Channels 1 to 150. You can scan these frequencies as soon  
as you turn on the scanner.  
1
After programming frequencies, press HOLD/RESUME to  
begin scanning. Or repeatedly press PVT until PRIVATE  
appears, if the scanner is in another mode. Your scanner  
scans all the channels upward.  
2. The bank number indicators (1-10) selected for scanning  
appear on the display, and the bank being currently  
monitored flashes. You can deselect banks from active  
scanning by entering their numbers on your keypad. The  
indicator for each deselected bank disappears, and the  
bank’s channels are not scanned.  
One bank must always be active. You cannot deactivate  
ll ten banks at the same time. If you try to deselect all  
the banks, the first bank is automatically selected.  
Note  
To restore a bank to active scanning, enter the bank’s number  
on your keypad. The bank’s indicator will display again.  
During normal scanning the scanner skips unprogrammed  
or locked out channels. When a transmission is received, the  
scanner stops on that channel. When the transmission ends,  
scanning resumes automatically.  
You can set the scanner to hold on a frequency for  
wo seconds allowing time for a response. For more  
information on the delay feature, see “Delay”.  
Notes  
During Signal Stalker operation, the delay time is 10  
seconds. After 10 seconds have elapsed, or if you press e  
or HOLD/RESUME, the scanner resumes search.

priority scan  
When priority scan is turned on, your scanner checks the  
priority channel in the banks you selected every two seconds  
for activity. If a signal is present on the priority channel, your  
scanner monitors the channel until the transmission ends,  
then resumes normal scanning. You can designate one  
channel in each bank as a priority channel. By default, the  
first channel in each bank is the priority channel, but you can  
change this.  
To activate Priority Scan (in either the private scan mode or  
scan hold mode):  
1. Press PRI. PRI appears.

highway patrol alerts  
Most highway patrol vehicles today come equipped with a  
secondary radio system known as a MOBILE EXTENDER or  
VEHICULAR REPEATER. Whenever the dispatcher transmits  
to any vehicle in the district, the mobile extender in every car  
within the district is activated. Using a constant PRIORITY  
CHECK of specific frequencies in each state, your scanner  
recognizes and alerts you to transmissions from “mobile  
extender” radios, as well as from car-to-car, aircraft to-car  
and other special-purpose frequencies. You receive an  
audible tone and visual alert (flashing light) whenever you are  
within approximately three miles of highway patrol or state  
police units using a mobile extender unit.

about Skywarn  
Skywarn is an organized group of trained weather observers.  
A Skywarn group exists in virtually every US county with  
a significant population. During inclement weather, reports  
made by Skywarn observers include information about:  
• pea-sized and larger hail  
• wind and wind gusts 40 MPH and greater  
• heavy rainfall  
• lightning (cloud-to-cloud and especially cloud-to-  
ground)  
• wall clouds seen in severe thunderstorms (which  
spawn tornadoes)  
• severe lowering of a wall cloud  
• turbulence in a wall cloud  
• funnel clouds  
• tornadoes  
• high water areas  
• downed power lines  
• other emergency conditions that affect life or property  
Listening to Skywarn broadcasts makes it easy to quickly find  
out about and prepare for inclement weather conditions in  
your immediate area, even before your local NOAA weather  
broadcast and local TV or radio station can announce them.  
Enter the local Skywarn frequency for your area into Channel  
1000 on your scanner. Then, listen to Skywarn first when  
severe weather threatens. Listen to NOAA: for weather alerts

and warnings, watch box notices, and weather forecasts.  
Listen to Skywarn to hear trained observers in your vicinity  
call in official reports to a “net control” station which relays  
those reports to NOAA and other emergency agencies.  
Most importantly, you get Skywarn reports directly from  
trained observers - that means you get them several minutes  
before they can be relayed for broadcast by NOAA and as  
much as 5 or 10 minutes sooner than you will hear them on  
local TV or radio! Those few minutes can be worth a lot when  
it comes to deciding if your family needs to take cover.  
f you tune to a Skywarn frequency when the Skywarn  
et is not active, you may hear nothing, or you may  
hear amateur radio operators talking on a local repeater  
system.

NWR SAME  
During weather mode, press FUNC +WX ALT to enable NWR  
SAME alert. When WX alert is on, ALERT lights and the audio  
mute is set on.  
Press FUNC + WX ALT to turn off the NWR SAME alert.  
If the scanner receives a SAME event code from the  
local weather service, it sounds an alert and displays the  
description for any alert received. Then, audio mute turns off  
and ALERT blinks.  
The scanner displays the following messages:  
Warning : L1  
Watch : L2  
Advisory : L3  
WX alert (1050 Hz): WXA  
During an alert, press any key to stop the alert. If you do  
not press any key, the scanner continues sounding the alert

Although the alert beep (warning beep, watch beep, advisory  
beep) sounds at short intervals for 5 minutes. After that, the  
emergency beep will sound at intervals of 10 seconds.  
programming a FIPS code  
To specify a county, SAME uses a standard established by  
the US Census bureau, called FIPS.  
The format of a FIPS code is:  
PSSCCC, where...  
P = area subdivision (0=entire area)  
SS = State code (00=all states)  
CCC = County code (000=all counties)  
For example, the FIPS code for Tarrant County, Texas is:  
048439 (48=Texas; 439=Tarrant County).  
Some counties are further subdivided, in which cases, the  
first digit will be 0 for all subdivisions in the county and each  
subdivision will be labeled 1-9.  
To program your scanner to alert you when the weather  
service issues an alert, you must set the scanner to the alert  
mode, and then leave the scanner monitoring the weather  
service. You cannot scan frequencies and monitor for  
weather alerts at the same time.  
To limit weather alerts to a specific area, you must also  
program in the FIPS code(s) for the area(s) you want to  
receive alerts. The scanner can be set to either, alert for all  
areas, or only the areas you have programmed.  
programming FIPS  
During weather scan, hold mode, press FUNC + PGM. The  
scanner sends itself into FIPS programming mode. If the  
scanner is set to alert for all FIPS, ALLFIPS appears on the  
display. If the scanner is set to alert only the area you have

has been inputted, the FIPS code is cleared.  
To set the scanner so it alerts you when you receive any FIPS  
code, press e or d to move ALLFIPS. Then press E. Then go  
to WX hold mode.  
To set to alert only the area you have programmed, press e  
or d to move F1 to F15. Then press E. Then go to WX hold

Signal Stalker  
Your scanner’s Signal Stalker feature lets you set the  
scanner so it detects and then displays the frequency of a  
nearby strong radio transmission. You can set the scanner  
so Signal Stalker works “in the background” while you are  
scanning other frequencies; turn off normal scanning while  
Signal Stalker works; or turn off Signal Stalker and use the  
scanner normally. You can set the scanner so it alerts you  
when Signal Stalker finds a frequency. You can also set the  
frequency band where you want the scanner to look for  
transmissions. You can also turn on the pager screening  
feature so the scanner ignores common pager frequencies.  
Signal Stalker works well for locating the source of strong

ocal transmissions, such as mobile and handheld two-  
way radios in areas with no other strong transmission  
sources; however, if you are in an area with many  
transmission sources (such as pager radio transmitters,  
multiuse radio towers, traffic control devices, etc.),  
Signal Stalker might not find the transmission you are  
searching for, or it might find a transmission other than  
the one you are searching for. You can screen unwanted  
transmissions by pressing L/O to lock them out. See  
“Frequency Skip” for more information.  
Signal Stalker cannot detect satellite dishes or any  
transmitter with a frequency above or below the  
frequency ranges listed under “Setting the Signal Stalker

trunk tracking  
Your scanner tracks three major types of trunked radio  
systems. These systems are described here.  
• MOTOROLA - Including Type I, Type II, Hybrid,  
SMARTNET, and Privacy Plus. Motorola systems are  
widely used by public safety and business users. Most  
are on the 800 MHz band. Recent systems appear on  
other bands. (See “Tracking Motorola Systems”).  
• EDACS - Including “Wideband” 9600 baud and SCAT.  
“Wideband” systems are mostly on the 800 MHz band,  
and are used by public safety, utilities, and business  
users. Some systems use VHF and UHF bands. (See  
“EDACS Tracking”). SCAT systems are single channel  
EDACS systems, and are mainly used in the midwestern  
United States.  
LTR - These systems are mostly for business users,  
and found on the UHF, 800 and 900 MHz bands. (See  
Tracking LTR Systems”).  
When tracking these types of systems, remember these  
important points:  
Your scanner defaults to monitor Motorola Type II 800;  
however, you can change this if the system in your area is  
different. (The types of systems are discussed below.)  
• If you have internet access, you can visit  
for current news and frequency information about trunk  
tracking scanning.

too high, it could prevent your scanner from locking on the  
control channel reliably. If it is set too low, it will slightly delay  
finding the control channel. The best setting is the same  
as for conventional reception and is critical for monitoring  
trunked systems.  
programming trunking frequencies  
There are three steps for programming a trunked system:  
1. Program the Trunk Type - enter the type of trunking  
system the scanner will track -- Motorola Type II, Type I,  
EDACS, LTR, etc.  
2. Program the trunked frequencies - within a trunked  
system, the frequencies are shared among all users.  
These frequency groups are called talk groups.  
3. Program the Talk Groups - Within a trunked system, each  
agency or department is assigned a talk group ID. This ID  
must be programmed into the scanner in order for it to  
monitor that specific agency or department.  
Before you start programming your scanner to track a  
trunked system, consider the following:  
You can only program one type of trunking system in  
each bank of your scanner.  
Trunked frequencies must be entered while in the trunk  
programming mode.  
• If you’re in the trunk programming mode, you cannot  
select channels in other banks. For example, if you are  
programming Bank 4, you can only select channels 301-  
400 by pressing e or d.  
f you are programming an EDACS trunked system, you  
must enter the frequencies in a specific order. Check

STEP 1: Selecting Trunking System Type  
The first step in a trunk tracking system is storing the  
frequencies in one of the ten available banks in your scanner.  
1. Press TRUNK in conventional programming mode. BANK  
and TRUNK will begin to flash on the display.  
2. Select the bank in which you want to store the frequency  
by using the keypad.  
3. Select the system you want to track by pressing e or d,  
then press E.  
List of trunking systems are as follows:  
E2-800 (Motorola Type II 800 MHz)  
E2-Hi (Motorola Type II VHF 136-174 MHz) *  
E2-UHF (Motorola Type II UHF 406-512 MHz) *  
E1 (Motorola Type I and Hybrid) **  
Ed (EDACS Wide Band: 9600 band)***  
Ed-SCt (EDACS Scat)  
Lt (LTR)  
* Requires programming of a base and spacing frequency offset channel (See  
“Setting the Base, Spacing Frequencies and Offset Channel for Motorola VHF/UHF  
Trunked Systems”).  
** Requires programming of a fleet map (See “Programming a User Fleet Map”).  
*** Requires programming of frequencies in exact order and location.  
STEP 2: Programming Trunking Frequencies  
1. Select Prog F and press E.  
2. Use the keypad and ./CLR to enter a frequency for the  
trunked system. For example, enter 851.0125.

3. Then, press E. E (EDACS), M (Motorola) or L (LTR)  
appears depending on the trunked system selected. If  
the frequency is out of the range of the system chosen in  
this step, you will hear an error tone, the channel number  
flashes and an error message appears on the display.  
4. Use the e or d key to select the next channel in the bank.  
5. Repeat Steps 2 through 4 until all frequencies have been  
entered.

programming id scan lists manually  
When you designate a bank as a trunking bank, your scanner  
sets up 10 scan lists, which are simply lists used to store your  
favorite talk group IDs. Each list can contain up to 10 IDs, so  
you can store a total of 100 IDs for each trunking bank. If you  
use all the banks for trunking, 1,000 IDs will be available.  
Once IDs are stored in lists, you can scan them like you scan  
conventional frequencies.  
1. Select the trunking programming mode and the bank you  
want to change.

Press TRUNK to start receiving trunked system information.  
You can receive the trunked system using the ID Scan Mode.  
You can receive those talk groups that you store in a scan list  
using ID Search Mode.  
You can hear all system talk group activity (except unit-  
to-unit calls). This mode lets you find unknown talk groups.  
Your scanner defaults to receive the talk groups in ID search  
mode. Press SRCH in the ID search mode and the scanner  
will move to the ID scan mode. If you press SRCH again, it  
will return to the ID search mode.  
ID scan mode  
When your scanner finds the control channel data, it begins  
trunking and id SCAN scrolls on the display until the scanner  
finds an ID. If you have not programmed any IDs, the scanner  
cannot stop on an active conversation.  
To remove a scan list from active scanning, press 1-9, 0 (the  
number of the scan list). The scan list indicator turns off, and  
the IDs in that list are not scanned.  
To restore a scan list to active scanning, press its number  
again.  
One scan list must always be active. If you try and

direct entry id hold mode  
Enter the ID you want to receive by using 1 through 9, 0 (or ./  
CLR) and press d, and you can listen to a specific ID (without  
storing ID to the list).  
ID search mode  
Once you have programmed all the frequencies for a  
trunked system, search will let you immediately start hearing  
transmissions. When in the trunking mode, press SRCH and  
the scanner begins to find any active IDs. When the scanner  
finds the control channel data, the scanner begins trunking,  
and -- --- appears on the display until the scanner finds an ID.  
If the scanner does not find an ID in about 1 second, it moves  
on to conventional channels in the same bank or to the next  
active bank. This may happen a few times (if the signal is  
weak) when the scanner comes around to that bank again.  
The scanner will recognize the control channel was lost when  
no ID can be found, even if the scanner tries ten times.  
The scanner will begin to search for the control data channel.  
If it finds any non-locked-out IDs, you will hear it. You will  
then hear any replies that follow within the specified periods.  
After that, the scanner will move on and not continuously  
search the system for additional IDs (on busy systems you  
would never leave the system if this were the case). If you  
press e while monitoring an ID, the radio will check if any  
other IDs are active (it will disregard the ID you just left), and  
none are active, the scanner resumes searching.

ID lockout  
Like conventional scanning, it is possible to lock out  
unwanted traffic. This is particularly important in trunked  
systems because in many areas, water meters, door alarms,  
traffic signals, and other mechanical devices are assigned IDs  
just like other users. Also, some departments scramble or  
encrypt their communications, and you may want to lock out  
these unintelligible broadcasts.  
To lock out an ID, press L/O on the ID you want to lock out.  
The ID is locked out. You can lock out up to 100 IDs. An error  
message (Full) appears when you try to register the 101st

system at a time. Here are some highlights of this feature:  
You can actually track up to 10 trunking systems at one  
time.  
You can trunk scan, or search and scan conventional  
frequencies at the same time.  
You can program conventional frequencies in the same  
bank as trunking systems.  
After the scanner finishes checking a trunked system for  
activity, it will conventionally scan the other frequencies  
in the bank (remember, only trunking frequencies are  
programmed in trunk mode).

about multi-track  
When more than one trunk system is active (for example two  
or more trunked systems or a trunked system and one or  
more conventional frequencies), the scanner jumps between  
systems/frequencies as follows:  
TRUNK SCAN: The scanner moves to a trunked system and  
looks for IDs in your scan list(s) for up to 1 second. If it finds  
no activity on your programmed talk groups, it moves on to  
conventional channels in the same bank or to the next active  
bank. If the scanner finds a talk group in one of your active  
scan lists, you will begin to hear that communication and the  
scanner will display the proper talk group number. When the  
communication ends, the scanner will wait for 2 seconds for  
any further replies and, if none, the scanner will move to the  
conventional channels in the same bank or to the next bank.  
The scanner will not look for any other IDs within the same  
trunked system (as this would slow the scan process). If you  
press the e key while you are listening to one ID, the scanner  
will check to see if another ID in your scan list is active. It will  
disregard the ID which you were just monitoring.  
TRUNK SEARCH: This mode works similarly to trunk scan.  
If the scanner finds any (nonlocked-out) ID when it checks  
the control channel, you will hear it. You will then hear any  
replies that follow within 2 seconds. After that, the scanner  
moves on and does not continuously search the system for  
additional IDs (on busy systems you would never leave the

Beyond the Basics  
system if this were the case). If you press the e key while  
monitoring one ID, the radio will check if any other IDs are  
active (it will disregard the ID you just left), and if none are  
active, it will move on.  
EDACS tracking  
Your scanner is now able to track EDACS trunked systems.  
Until now, these widely used systems have been almost  
impossible to monitor with a conventional scanner. With your  
scanner, listening to EDACS is remarkably easy, and perhaps  
even easier than conventional scanning.  
EDACS systems use “Transmission Trunking”, which means  
that each transmission is assigned a new frequency.  
As the conversation moves through the system’s  
frequencies, your scanner automatically follows it. Your  
scanner can clearly and automatically follow this talk group,  
or any other, as you select. EDACS systems are organized  
in a logical way that keeps related talk groups together. Your  
scanner is designed to take maximum advantage of this  
organization to make your scanning easy. It lets you zero in  
on just the part of the system you want to hear, whether it is  
an individual channel, an entire department or city.  
programming EDACS system frequencies  
When you program EDACS frequencies, it is critical that  
you store each one in the correct location. By the nature of  
EDACS systems this is necessary for tracking. This often is  
not the frequency order, so you must be sure you have the  
right sequence. Sources for this information can be found at

an EDACS trunked system  
Your scanner shows EDACS talk groups in AFS (Agency-  
Fleet-Subfleet) format. This helps you see, at a glance, who  
you are monitoring. And with the partial-entry feature, you  
can easily include nearby, related channels in the same fleet  
or agency. You can just as easily exclude entire unwanted  
fleets and agencies.  
When in search mode, with the system frequencies  
programmed, and your scanner locked to the control  
channel, you can select a desired city by keying in the agency  
part of the AFS talk group. When you hear an interesting talk  
group, in hold mode capture it to your scan list by pressing E  
during the transmission. Or hold on it by pressing  
HOLD/RESUME.  
Your scanner can also work in decimal format. Talk group 03-  
62 in decimal format is 402. But decimal format does not give  
you any information about the system hierarchy. Decimal is  
useful if you need to work from decimal talk group lists.  
special EDACS features  
AFS partial entry  
AFS is a method of encoding EDACS talk groups. AFS stands  
for Agency-Fleet-Subfleet”. AFS talk groups are used in all  
EDACS reception -- in ID search, ID lockout and ID scan. The  
powerful AFS partial entry feature designed into the scanner  
lets you use either a complete talk group code, or just the  
most significant part.  
This feature lets you expand or narrow searching and  
scanning to one of 4 levels. By entering only the desired  
part of an AFS talk group, you can select 2048 talk groups,  
128 talk groups, or 8 talk groups. For example, you could  
program every talk group in a police department with just  
4 key presses. You can use the AFS partial entry feature  
60

Beyond the Basics  
anywhere you need to specify EDACS talk groups.  
Your scanner can also enter or display EDACS talk groups in  
decimal format (0-2047).  
1. Select the trunking programming mode and the bank you  
want to change.  
2. Press e or d to select EDACS, then press E.  
3. Press e or d to select AFS, then press E.  
4. Press e or d to select AFS ON or AFS OFF, then press E.  
You can use this feature to translate decimal talk group lists  
to the much more powerful AFS format. It is very easy to use.  
Be sure to become familiar with AFS partial entry, and your  
scanning will become far more flexible and efficient.  
EDACS ID range search  
When your scanner searches EDACS talk group IDs, the  
scanner can search within a range you set for agency or fleet  
listings. For example, if you want to search within the 01  
agency, while in hold mode press 0, 1, ./CLR then SRCH. Or  
if you want to search within the 01 agency and 01 fleet, while  
trunking press 0, 1, ./CLR, 0, 1, then SRCH.  
To stop the ID range search, press e while the talk group is  
deactivated.  
EDACS ID blockout  
EDACS blockout can be used only with AFS and EDACS  
systems. This feature lets you lock out entire Agencies or  
Fleets, not just individual talk groups. To use this, just enter  
the Agency-part, or the Agency-Fleet part, of the talk group  
code and press L/O. For example, to block out agency 04 in  
trunk search, press HOLD/RESUME, 0, 4, ./CLR, and then L/O.

EDACS SCAT  
With the EDACS SCAT feature, the data stream transmissions  
will be eliminated, allowing you to clearly monitor the voice  
communications on EDACS SCAT systems.  
To monitor EDACS SCAT systems you only need to program  
the frequency in the trunk tracking programming mode. You  
do not need to enter group IDs.  
tracking LTR systems  
LTR (Logic Trunked Radio) systems are trunking systems  
used primarily by business or private communications  
service providers, such as taxicabs, delivery trucks,  
and repair services. These systems encode all trunking  
information as digital subaudible data that accompanies  
each transmission. Users on an LTR system are assigned to  
specific talk groups, which are identified by the radio as six  
digit numbers.  
These numbers are in the form AHHUUU, where:  
A= Area code (0 or 1)  
H= Home repeater (01 through 20)  
U= User ID (000 through 254)  
When the scanner receives a transmission on a channel set  
to the LTR mode, it first decodes the LTR data included with  
the transmission. In the ID Search mode, the scanner stops  
on the transmission and displays the talk group ID on the  
display. In the ID Scan mode, the scanner only stops on the  
transmission if the LTR data matches a talk group ID that  
you have stored in the bank’s talk group ID list and have not  
locked out.  
LTR systems are frequently programmed so that each radio  
has a unique ID code.

tracking Motorola systems  
There are really two types of Motorola trunking systems.  
These are usually referred to as Type I and Type II systems.  
Type I only occurs on some 800 MHz systems. All VHF and  
UHF trunking systems use Type II. One important distinction  
between these two systems is the amount of data transmitted  
by each radio when its push-to-talk button (PTT) is pressed.  
Every radio in a trunked system is assigned a unique ID so  
the central site computer can identify it when it’s used. Both  
Type I and Type II systems place radios (or radio users) into  
groups, called talk groups, and these talk groups are also  
assigned unique IDs. Some radios have access to only one  
talk group, while others have access to many talk groups.  
The talk group(s) each radio can access is called the radio’s  
affiliation(s). In a Type II system, when someone uses their  
radio, only the radio ID is transmitted when PTT is pressed,  
whereas in a Type I system the radio ID and its current  
affiliation are both transmitted when PTT is pressed.  
Why the difference? Type II systems are slightly more  
advanced because the central computer maintains  
a database which is used to determine each radio’s

Changes to a Type II system are easier than Type I because  
the system manager only needs to update the database  
instead of reprogramming individual radios.  
Another difference between the systems is that Type I  
systems are arranged in a fleet-subfleet hierarchy. For  
example, it is possible for a city using a Type I system to  
designate 4 fleets, each with 8 subfleets. Their fleets might  
be the police department, the fire department, utilities, and  
administration. The police may decide to further divide their  
fleet into subfleets such as dispatch, tactical operations,  
detectives, north, south, east and west side patrols, and  
supervisors. All the available police radios would then be  
assigned to one of the police subfleets. Determining the

Beyond the Basics  
exact fleet-subfleet hierarchy for a particular area is referred  
to as fleet map programming, which is discussed further in  
this manual.  
The disadvantage of a Type I system is that when PTT is  
pressed, the brief burst of data must contain the radio’s ID  
and its fleet and subfleet. This is three times the amount of  
data a Type II radio sends, and as a result Type I systems  
usually accommodate fewer users than Type II systems.  
Even though there are many Type II systems, Type I systems  
are still in use. There are also Hybrid systems which are a  
combination of both Type I and Type II. Your scanner defaults  
to monitor Type II systems, but it is possible to select a  
preprogrammed fleet map or create a custom fleet map for  
your area. For VHF and UHF Type II trunking systems, you  
will need to know the base, spacing frequencies and offset  
channels. See “Setting the Base, Spacing Frequencies and  
Offset Channel for Motorola VHF/UHF Trunked Systems” for  
details.  
fleet map programming  
If you have programmed a trunk tracking bank for Motorola,  
press TRUNK to start multi-track, and you will see user IDs  
on the display. Since the scanner defaults to Type II systems,  
all the IDs will appear as numbers; however, if you notice a  
mix of odd and even user IDs, for example 6477, 2560, 6481,  
6144, 1167, etc., then you are probably monitoring either a  
Type I or a Hybrid system.  
You may also notice that you are missing responses when  
you hold on an active ID. Unlike Type II, Type I/Hybrid  
systems require a fleet map that sets specific fleet-subfleet  
parameters. It is easy to select a fleet map for your scanner;  
what is not always easy is selecting or programming a map  
that matches your particular area.

There are 16 preset fleet maps from which you can choose,  
and these are usually a good place to start when setting up a  
Type I/Hybrid trunk tracking bank. If you choose a preset map  
and still have difficulty following complete conversations,  
then you’ll have to program your own fleet map.

Selecting a Preset Fleet Map  
1. Select the trunking programming mode and the bank you  
want to change.  
2. Press e or d to select E1, then press E.  
3. Press e or d to select FLEEt, then press E.  
4. Press e or d to select the map you want, then press E.  
The scanner returns to fleet map list item.  
ou will now begin to see Type I fleet-subfleet IDs. For  
Note  
xample, 100-12, 100-9, 000-12, 400-8, etc. See “User-  
Defined Fleet Maps” for more information about Type I  
IDs.  
How do you know if the preset map is correct? You will have  
to listen to see if you’re following complete conversations. If  
not, try another preset map.  
user-defined fleet maps  
When a Type I system is designed, the address information  
for all the IDs are divided into 8 equal sized blocks. When  
you program your scanner to track a Type I system, you  
must select a size code for each of these blocks. When you  
have assigned a size code to all 8 blocks, you have defined  
the fleet map for the system you’re tracking. Each size code  
determines the number of fleets, subfleets, and IDs each  
block will have. For example, a size code of “4” has one fleet,  
which is divided into 16 separate subfleets, and it has a total  
of 512 individual IDs.  
When a block is assigned a size code, the fleet or fleets  
created within the block are assigned a Type I ID. The way  
these IDs display on your scanner depends on the block  
number and the blocks size code. When a Type I ID displays,  
the left most digit represents the block which contains the ID.  
68  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Beyond the Basics  
The next two or three digits identify which fleet is active, and  
the last digit(s) identifies the subfleet.  
Your task is to program your fleet map with the same size  
code assignments as the trunked system. If you do this  
accurately, you’ll track all the fleet-subfleet combinations  
used by the system. In other words, you’ll hear complete  
communications while monitoring a trunked system.  
If you don’t already know the size codes used, you’ll have to  
guess at them. But since you don’t have to figure out all the  
blocks at once, this isn’t as hard as it seems. Select a size  
code for a block, and then press SRCH. Now listen to the  
communications. If you decide you are receiving most of the  
replies to the conversations with IDs assigned to the block  
you just programmed, then you’ve probably selected the  
right size code and can work on the next block of the map.  
Finally, for most public safety systems there are some size  
codes which are more common. Size code 3 and size code 4  
are probably the most common, followed by size codes 10,  
11, and 12.

size code restrictions  
If you select size code 12, 13, or 14, there are some  
restrictions as to which blocks can be used for these codes.  
• Size code 12 can only be assigned to blocks 0, 2, 4, or 6.  
• Size code 13 can only be assigned to blocks 0 and 4.  
• Size code 14 can only be assigned to block 0.  
Since these size codes require multiple blocks, you will be  
prompted for the next available block when programming a  
fleet map. For example, if you assign block 0 as size code 12,  
you will be prompted for block 2, the next block available,  
instead of block 1. And if you assign block 0 as size code  
14, you would not see another prompt because all available  
blocks have been used.  
programming a user fleet map  
1. Select the trunking programming mode and the bank you  
want to change.  
2. Press e or d to select E1, then press E.  
3. Press e or d to select FLEEt, then press E.  
4. Press e or d to select USr, then press E.  
5. Press e or d to select the size code for the first block, then  
press E. The next available block appears on the display.  
Then, repeat this step until you have selected a size code  
for each block.

II, select size code S-0.  
When you begin searching a trunking bank with a Hybrid  
fleet map, you will see both types of system IDs. That is,  
Type II IDs usually appear as an even number without a dash;  
Type I IDs appear as a three or four digit number, followed by  
a hyphen, followed by a one or two digit number.

Notes  
f the system is not tracking properly, you may need to try  
a new base frequency or offset channel, or you may be  
missing frequencies from the system.  
You can set up to three base, spacing and offsets for  
Motorola VHF/UHF trunked systems.  
toggling the status bit  
On Type II trunking systems, there is a method by which  
specialized types of communications use unique talk group  
numbers. An emergency call will occur on a unique talk  
group from its primary assignment, for example. Because  
the scanner defaults to status-bit on mode, you never need  
to worry about missing these transmissions. If you have  
programmed talk group 33264 into scan list memory, for  
example, and there is an emergency call within that group,  
you will hear it on 33264.  
The only time you may wish to turn status bits off is if you’re  
trying to figure out the proper fleet map of a Type I trunking  
system.  
1. Select the trunking programming mode and the bank you  
want to change.  
2. Press e or d to select E1, E2-800, E2-Hi or E2-UHF, then  
press E.  
3. Press e or d to select S-bit, then press E.  
4. Press e or d to select Sbt ON or Sbt OFF, then press E.

control channel only mode  
When this function is activated, trunking is performed using  
control channel data only. Voice channel (also known as  
“DATA channel”) frequencies do not have to be programmed  
into memory. This feature only applies to Motorola 800 MHz  
systems.

When you deselect control channel only mode, CC OFF  
appears on the display. Read the descriptions of the Plan 1~4  
for details on which may apply for you.  
PL1 (plan 1): This plan is the most common. Use Plan 1 if  
the last three digits of ALL the frequencies in use end in one  
of the following three digits: 125, 375, 625, or 875 (example:  
856.1125, 860.7375, 859.6625, 855.8875).  
PL2 (plan 2): If the last three digits of frequencies are less  
than 860.000 and end in one of the following three digits  
(125, 375, 625, or 875) and if ANY other frequencies end in  
(000, 250, 500, or 750) use Plan 2.  
PL3 (plan 3): If the last three digits of ALL the frequencies in  
use end in one of the following three digits (000, 250, 500, or  
750) use Plan 3.

(125, 375, 625, or 875) use Plan 4.  
Of course you will know the control channel frequency itself  
so that will help you determine the proper plan. If you try one

to channels that are obviously not part of the system), you  
should try an alternate Plan.

canned in control channel only mode by going into the  
trunk programming mode. You can also program IDs, set  
a delay, and all the other parameters for systems scanned  
in this mode. You can then either search the system to  
find new IDs or you can program IDs into memory and  
then scan them.  
The control channel only feature is an extremely powerful  
tool. You can use it to determine if systems you are  
familiar with may have added new frequencies or you can  
use it to discover new systems by simply finding active  
control channels (using search), and then programming  
them for control channel operation only.  
Remember that this feature only applies to Motorola 800  
systems, that you do have to set the proper system type  
(800 MHz of Type 1 or Type 2) and you do have to program  
the control channel frequency into memory and identify the  
frequency as trunked in the trunk programming mode.  
disconnect tone detect option (end code)  
When this function is disabled, the radio looks for squelch  
before returning to the control channel instead of waiting for  
the disconnect tone. Only in rare instances will you need to  
adjust the default settings. The condition to return to control  
channels depends on whether the signal is present or not.

cloning your scanner  
You can clone all the frequencies, trunking talk groups, and  
fleet maps programmed in your PRO-2051 to another  
PRO-2051 using an optional interface cable and software  
(available at your local RadioShack or www.radioshack.com).  
1. Make sure the scanners are turned off and then plug the  
cable into each scanner’s PC/IF jack.  
2. While you press and hold E on both scanners, turn on  
both scanners.  
3. Determine the scanner which has the frequency data that  
you want to transfer. This one must be set up as the “First  
Unit”, and the other must be set as the “Clone Unit”.  
4. On the scanner that is the “Clone Unit”, press e or d to  
select CLONE, then press HOLD/RESUME.  
5. On the scanner that is the “First Unit”, press e or d to  
select FirSt, then press HOLD/RESUME. The data transfer  
begins from the First Unit to the Clone Unit.  
During data transfer, SNDFirSt appears when a scanner is  
sending data and REC CLONE appears when a scanner is  
receiving data. When the data transfer is complete, donE  
appears. If the data transfer is not successful, Error appears.

frequently asked questions (FAQs)  
Q: I drive by patrol cars but do not hear alarms?  
A: Make sure you are scanning in Highway Mode. Check your  
antenna connections. In some cases, the alarm might not  
go off depending on the proximity of the patrol car to your  
vehicle. Also, terrain or other factors might be involved.  
Police officers can turn off the mobile extender when off duty  
or when going to court; however, they normally leave them  
on when on traffic duty. If you monitor user-programmed  
frequencies, switch to one of the preprogrammed frequency  
banks. Make sure MUTE and FLASH are both turned off. Some  
priority frequencies may be locked out.  
Q: My scanner is on but won’t scan or reception is weak. How  
do I get it to scan?  
A: Make sure the AC adapter is securely connected. If you are  
using an AC adapter and the wall socket it is plugged into is  
controlled by a wall switch, make sure the wall switch is turned  
on. If reception is poor, check the antenna connection or  
move the scanner. You might be in a remote area which could  
require an optional multi-band antenna. Check with your local  
RadioShack store.  
Q: My scanner is not receiving weather channels. How do I set  
it so I can receive weather channels?  
A: The scanner might be set to weather alert mode. If this  
happens, it cannot receive weather channels until it receives  
a weather alert. To hear a weather channel at any time, make  
sure weather alert is turned off. See “NWR SAME” for more  
information.

Q: Error appears on the display. What does it mean?  
A: If you were trying to enter a frequency, you might have made a  
programming error. Re-enter the frequency correctly, including  
the decimal point.  
Q: My scanner does not track EDACS systems properly. What’s  
wrong?  
A: The logical channel numbers (frequencies) for the system  
might not be programmed in the correct order, or all the  
frequencies might not be programmed. Check the frequencies  
and reprogram them.  
Q: I do not hear all the replies to conversations. What’s wrong?  
A: Change to a Type 1 scanner setup. See “Fleet Map  
Programming” for more information. Try another preset fleet  
map or program your own fleet map. Check to see that all the  
system’s frequencies have been entered.  
Q: The scanner does not acquire the data channel. What’s  
wrong?  
A: Adjust the squelch for trunking mode. See “Setting the  
Squelch”. Also, the frequency used for the data channel might  
not have been programmed into the scanner.
