Note: In general, the radio transmit and receive time  
(operating cycle time) is determined by the communica-  
tion system. On overload, respectively on extensive use  
beyond the systems specifications at high ambient tem-  
peratures, the radio is protected by its thermal control,  
which cuts down the RF output power, thus reducing  
the radio coverage range.

Charging the Battery  
Motorola approved chargers provide optimum performance.  
Other chargers may not fully charge your Motorola Lithium-  
Ion battery or may reduce the life of the battery.  
The MTH800 can be either On or Off during charging.  
1. Insert the connector on the charger into the socket at the base  
of the MTH800. Select the required plug adapter (UK or Euro-  
pean type) and connect to the charger. Then plug the charger  
into a suitable mains socket.  
2. The MTH800 displays the Charger Connected message only  
if the MTH800 is On when connecting the charger. If the  
MTH800 is Off, the display shows an icon of the battery in  
charging.  
The Battery icon shows the charging status (see below).

Battery Maintenance  
The performance of the rechargeable battery delivered with  
your terminal depends on the way the battery is treated.  
Therefore, to comply with the Motorola warranty for batteries  
and to assure high performance and a long life cycle of your  
Motorola rechargeable battery, please read and follow the  
maintenance rules stated below.  
Storage  
Do not store your battery where the temperatures will exceed  
65 °C or fall below -20 °C.  
New Lithium-Ion batteries (i.e.batteries that have never been  
charged before) may be stored for up to 2 years (with up to  
50% of maximum charge) in well ventilated, cool and dry  
areas with some capacity loss in life cycle.  
Batteries, which have already been charged and then stored  
for more than 2 months should be recharged overnight (14-  
16 hours) before use.

Extending Battery Life  
A battery is an expendable part and may need replacing  
during the life of the terminal.To ensure maximum service life  
of your handset, always replace the battery with a genuine  
Motorola replacement.  
In order to ensure maximum life from your battery, do not  
place the handset and/or battery in the charger, unless you  
really want to charge the battery.  
Battery Charging Temperature  
Your charger will only charge your battery when it is at  
temperature range of 1 °C to 37°C.  
This is due to the fact that the internal battery cell can be  
charged in the temperature range of 0 °C to 45 °C.  
As the temperature gets colder (close to 0 °C) less capacity  
is stored in the battery.  
If, during charging, the temperature is out of range, the  
battery might not be fully charged since the charging is  
temporarily stopped until the temperature becomes suitable.  
The range of battery operation is from 0 °C to +45 °C in  
charger mode and from -10 °C to +60 °C in discharge  
(application) mode.  
First Time Battery Charging  
Always charge your new battery/(whichever type) overnight  
(14-16 hours) before using it.This is referred to as Initialising  
and will ensure maximum battery start capacity.  
Battery Charging Rules  
Generally, to reduce the number of charge cycles as much  
as you can wait for Low Battery message to charge as this  
will ensure maximum battery life.  
Do not use your charger as a terminal stand or leave your  
terminal and fully charged battery connected to the charger  
whilst not charging. Continuous charging will shorten the  
battery life.

Selecting Your Network  
Before you start operating your MTH800, you can select the  
network you want your MTH800 to be registered to. For  
detailed information, see “Networks” on page 101.  
How to Hold Your MTH800  
The terminal has two microphones: a top microphone for  
half-duplex dispatcher calls and a bottom microphone for full-  
duplex telephone-like calls.  
A call can be placed in high or low audio. To activate low or  
high audio, see page 21.  
In high audio the user transmits via the top microphone and  
listens via the internal speaker.  
In low audio the user speaks into the bottom microphone and  
listens via the earpiece.  
Group and Private Calls are half-duplex calls and can be  
placed in high or low audio.  
Phone, PABX, and full-duplex Private Calls are placed in low  
audio. The speakerphone feature allows to hold Phone,  
PABX, and full-duplex Private Calls via the MTH800 internal  
speaker.  
13  
                 
Use in Low Audio (Phone, PABX, and Full-duplex Private  
Calls)  
When placing or receiving a call and while speaking, hold  
your MTH800 as you would a telephone. Speak into the  
bottom microphone. Listen via the earpiece.  
Keep antenna at least 2.5 centimetres from your head and  
body.  
Use in High Audio (Group and Private Calls)  
Hold MTH800 in a vertical position with its top microphone  
5.0 to 10 centimetres away from your mouth. Speak into the  
top microphone. Listen via the terminal's internal speaker.  
Keep antenna at least 2.5 centimetres from your head and  
body.  
Lapel/Shoulder Use  
For Group and Private Calls turn your head towards your  
shoulder/lapel, and speak directly into the top microphone.  
Listen via the terminal's internal speaker.  
Speakerphone Use  
Place the MTH800 30 to 60 centimetres away from you. In a  
noisy environment, you may want to move the MTH800 closer  
to you for better transmission.  
Looking after your MTH800  
Never leave your MTH800 or battery in extreme  
temperatures (over 60 °C)—for example, behind windscreen  
in very hot, direct sunlight. Do not immerse your MTH800 in  
water.  
To clean your MTH800, use a moistened or antistatic cloth.  
DO NOT use a dry or electrostatically charged cloth.

Terminal Disable/Enable  
Your MTH800 is provided with a feature that allows your  
Service Provider to disable it temporarily in case it is  
stolen.When your MTH800 is disabled, no calls can be  
initiated or received.  
While your MTH800 is disabled, it will look and act like it is  
turned Off.  
If you try to turn your MTH800 On, when it is disabled, it will  
operate as described above.  
If your MTH800 is found, your Service Provider can re-  
enable it. After your MTH800 is re-enabled, you may resume  
normal operation.  
Selecting TMO or DMO Operation  
General  
In Trunked Mode Operation (TMO) the MTH800 is used with  
the infrastructure services within system coverage.  
In Direct Mode Operation (DMO) the MTH800 is used without  
infrastructure services required.  
While operating in DMO the propagation travels directly from the transmit-  
ting terminal antenna to the receiving terminal antenna, with no assistance  
from any base station or tower. Therefore, the range is critically dependent  
on the position of the user and the antenna. To achieve best results, hold  
the terminal in the hand as high as comfortably possible, and be sure not to  
obstruct the antenna in any way. Be sure that the antenna is clear from the  
body, cables, or other obstructions. As there is no tower-mounted base sta-  
tion to assist, and the two users are usually standing at ground level, the  
range is usually shorter than that can be achieved towards a tower or hilltop.  
Any obstructions (hills, buildings, etc.) between the users will further  
decrease the range. Conversely, raising the terminal higher or moving to a  
higher location may improve the range.  
23  
           
A MTH800 in DMO can communicate with the trunked  
system (and vice-versa) through a gateway device. To use  
that feature, please enable the gateway option in your  
MTH800 (see “Making a DMO Group Call via Gateway” on  
page 43).  
In DMO it is only possible to place Group calls and Emergency Group Calls.  
Entering TMO or DMO  
Enter TMO or DMO in one of the following ways:  
• From the Home display press Optns and select Direct Mode  
if the MTH800 is in TMO.  
• From the Home display press Optns and select Trunked  
Mode if the MTH800 is in DMO.  
• Press  
and select More...> Networks > Trunked  
Mode if the MTH800 is in DMO.  
• Press  
and select More...> Networks > Direct Mode  
if the MTH800 is in TMO.  
• Press the TMO/DMO one-touch button (if programmed by  
your Service Provider).  
Your terminal can alert you of an incoming call. Select the alert settings in  
the Vibrate menu and Tones menu items.  
TMO Calls  
You can make and receive the following types of calls when the  
MTH800 operates in Trunked Mode:  
• Group Calls  
• Private Calls  
• Phone Calls  
• PABX Calls—local (office) extension calls  
• Emergency Calls  
24  
   
DMO Calls  
You can make and receive Group Calls when the MTH800  
operates in Direct Mode (DMO). This includes Emergency Group  
Calls.  
The MTH800 returns to the Home display when there is no activity  
for a few seconds.  
Making Calls  
See the relevant sections in the user guide.  
Modifying the Type of Call  
The infrastructure can modify the type of call you started.  
For example, you might start a a half-duplex Private Call, and  
the infrastructure could modify the call to a Group Call.  
The terminal will alert you of the modification and will display  
the following messages, depending on the type of call:  
Call Modified (to full-duplex)  
Call Modified Use PTT (modified to half-duplex)  
Continue the modified call depending on the type of call.  
• Half-duplex Private Call modified from direct setup to hook setup:  
a ringing tone will alert of the change.  
• Half-duplex Private Call modified from hook setup to direct setup:  
there will be no indication of the change.  
Receiving Calls  
The MTH800 will automatically receive the incoming call.  
Additionally, if Inactivity Revert Mode is enabled, the  
MTH800 returns automatically to the Home display, after  
that call ends.  
Inactivity Revert Mode will occur if configured by your Service Provider.  
25  
             
Your MTH800 will alert you of an incoming call depending on  
the setting you selected in the Vibrate menu option (see  
page 81) and the Tones menu option (see page 85).  
During message editing, you will be alerted of an incoming  
Group/Emergency/Broadcast Group Call if configured by  
your Service Provider.  
Preemptive Calling  
Preemptive calling is particularly useful when you need to  
speak urgently with a user whose terminal is busy in a non-  
emergency voice call.  
A preemptive priority call (PPC) is either an Emergency  
Group Call or a Private PPC (half-duplex or full-duplex call).  
The feature allows to disconnect the on-going lower priority  
call and to connect to the incoming higher priority call.  
To place a PPC, see the Emergency Operation and Private  
Call sections in the user guide.  
The MTH800 will receive the call via speaker or earpiece,  
according to the setting used when the PPC is received.  
For call alert, see settings in the Vibrate menu option (page 81) and the  
Tones menu option (page 85).  
Receiving a PPC is explained in the following paragraphs.  
In the screens, <Any> in Use refers to any of the non-  
emergency voice calls: Group, Private, Phone, or PABX.

Ambience Listening (AL)  
This feature, if enabled by your Service Provider, allows a  
console operator (or dispatcher) to establish a special call  
with a specific terminal to monitor voice activity in the local  
vicinity. The call is setup without any indication to the  
affected terminal, and any lower priority ongoing voice call or  
packet data transfer may be pre-empted.  
After accepting the call, the terminal transmits in a half-  
duplex Private Call without any action from or indication to  
the user. The Ambience Listening call shall automatically end  
when the user initiates any voice call and uses the terminal  
normally.

Local Area Service  
This mode, also called Fallback Mode, allows more than one  
terminal from the same site to communicate when the link  
between the site and network central controller fails. Entering  
and exiting Local Area Service (that is, returning to System  
Wide Services) is done automatically.

TMO Group Call  
General  
A Group Call is an instant communication between you and  
others in a talkgroup that you select. Participants may join  
(late entry) and leave an on-going Group Call. A talkgroup is  
a pre-defined set of subscribers enabled to participate in and/  
or invoke a Group Call, that is set up by your Service  
Provider.  
Talkgroups appear on your display as names or numbers (for  
example: Sales, Service, Electricians, Talkgrp10).  
Talkgroups are divided into folders. Each folder may contain  
several talkgroups.  
For ease of use, your MTH800 also provides the ability to:  
• Perform an alphabetical search of the talkgroup aliases.  
Scroll through the entire talkgroup list.  
• Organise your favourite groups into one folder called My  
Groups (set up by your Service Provider).  
Your talkgroups may be organized into scan lists (set up by  
your Service Provider, or by yourself through the Menu).  
When you activate one of these scan lists, your MTH800 will  
continuously monitor the activities of the selected talkgroups.  
By assigning priorities to the talkgroups defined in the scan  
list, you will be capable of accepting calls that have higher  
priority than the on-going call.  
You can start talkgroup, folder, or scanning selection when  
the terminal is idle or receiving a call.  
When receiving a call, choose one of the following:  
• Exit selection screen to join the call.  
• Join the call from the selection screen by pressing PTT.  
• Continue selection.  
32  
               
Each talkgroup may have one associated Announcement  
Talkgroup (ATG) that it monitors (if set up by your Service  
Provider).  
An ATG is a special group which is linked to a number of  
talkgroups and has the highest priority level, thus enabling  
broadcast of the call to all these talkgroups.  
When an ATG is selected, the scanning icon is not displayed.  
The MTH800 monitors the ATG scan list instead of the  
selected scan list. The ATG scan list contains all the  
talkgroups associated with a selected ATG. Your Service  
Provider should advise what talkgroups are associated with  
which Announcement Talkgroup.  
Your MTH800 will always monitor the Group Calls in the ATG  
scan list. To place an Announcement Call, you must first  
select the specified Announcement Talkgroup as advised by  
your Service Provider, otherwise you will only be able to  
participate when an Announcement Talkgroup is received.  
Activation and deactivation of talkgroup scanning has no  
effect on the ATG scan list.  
Dual Microphone Feature  
See “How to Hold Your MTH800” on page 13.  
Selecting a Group  
You can select a talkgroup in one of the following ways, by  
using the:  
• Rotary knob  
• navigation key  
• alphabetical search feature  
• folder search  
For group scrolling configuration, see page 35.  
When you navigate in the “My Groups” folder and select a DMO group, your

has Group21 and Group22. Group11, Group12, Group21,  
Group22 will appear during scrolling.  
OR  
35  
                   
• Stay in folder—when the folder end is reached during  
group scrolling, further scrolling restarts the folder group  
list. To move to the next Folder, you should select it.  
For example: Folder 1 has Group11 and Group12. Folder  
2 has Group21 and Group22. Select Folder 1: Group11,  
Group12, Group11,Group12 will appear during scrolling.  
Change to Folder 2: Group 21, Group 22, Group 21, and

Any incoming Group call is ALWAYS received through the main speaker. If  
configured by your Service Provider, the Group Audio menu item allows to  
setup the audio of the incoming Group Call.  
If the setup is Speaker Control, you can direct the audio of an active group  
to the earpiece (low audio) or the main speaker (high audio). In low audio  
speak into the bottom microphone and listen via the earpiece. In high audio  
speak into the top microphone and listen via the speaker.  
At the end of a call which has been directed to the earpiece, an audio hang  
timer is activated, if it is enabled by your Service Provider. Within the  
preprogrammed hang time, any incoming call is still received through the  
earpiece. When the timer expires, a low pitch tone is emitted alerting you  
that the next incoming Group call will be received through the speaker.  
Upon hearing this alert, you are advised to hold the terminal at a  
comfortable distance away from the speaker.

Transmit Inhibit  
You can activate the Transmit Inhibit (TXI) Mode before  
entering RF sensitive areas, e.g. in hospitals or in potentially  
explosive areas, where safety can be jeopardized due to  
MTH800 transmission radiation.  
Radiation of the MTH800 is only suppressed if the TXI Mode is acti-  
vated or the MTH800 is separated from power supply.  
In TXI Mode the MTH800 will not transmit under any circum-  
stances, except for the Emergency Call, which can be initi-  
ated even if the MTH800 is in TXI Mode.  
All MTH800 functions and keys which cause transmission,  
e.g. registration to the network, change of talkgroup or folder,  
sending messages, pressing PTT, etc. are disabled. In this  
case the display shows “Not Allowed In TXI Mode” and the  
MTH800 sounds the “Transmit Inhibit” tone.  
39  
               
When no danger to safety exists anymore (for instance if you  
leave the RF sensitive area), the TXI Mode can be deacti-  
vated and the MTH800 returns to standard operation.  
Setting the TXI Mode is described in “Setting Transmit Inhibit  
(TXI) Mode” on page 102.

Dynamic Group Number Assignment (DGNA)  
DGNA provides the ability for a network operator or  
authorised user to dynamically allocate new, or update  
existing talkgroups to selected terminals over the air  
interface. Using supplementary services messages (SS-  
DGNA), the network operator can command your terminal to  
add talkgroups or to update the existing talkgroups, or to  
delete talkgroups from the list. This operation is performed by  
transmitting the data into your MTH800.  
Your Service Provider can gather some Talkgroups under one Super-  
group and transmit it to your MTH800 as a DGNA. In such a case, you  
will be able to participate in calls to/from all the groups in the Super-  
group.  
DGNA Reception with Notification Message  
When a DGNA message is received and  
DGNA notification was configured by your  
Service Provider, you will get a tone

DMO Group Call  
General  
In DMO, the MTH800 can be used without your Service  
Provider’s infrastructure.  
Direct Mode allows communication with other terminals also  
operating in Direct Mode, which are on the same frequency  
and talkgroup as your MTH800.  
In DMO it is only possible to place Group Calls and Emergency Group  
Calls.  
You can receive a call:  
• From the selected talkgroup  
• From other users within talkback range (if configured by  
your Service Provider). This is called an InterMNI (Mobile  
Network identity) call.  
• From an open group. (An open group is a super-group to  
which all DMO groups belong.)  
When you start a call, the members of the selected talkgroup  
who have their units turned on, and are within the group  
subscriber identity (as configured by the Service Provider),  
will receive the transmission.  
In DMO the MTH800 can communicate with the trunking  
system (and vice-versa) if the Gateway option is enabled in  
the MTH800.

Private Call  
General  
A Private Call, also called Point-to-Point or individual call, is a  
call between two individuals. No other terminal can hear the  
conversation. This call can be a full-duplex call (if the system  
allows) instead of the standard half-duplex call. In a full-  
duplex call, both participants can speak at the same time,  
while in a half-duplex call, only one person can speak at a  
time.  
For operating the MTH800 in RF sensitive areas, see “Trans-  
mit Inhibit” on page 39.  
While Transmit Inhibit is activated, an incoming Private Call is indi-  
cated, but it is not possible to answer the call.

configured).  
The Emergency Alarm is a special Status message sent to  
the infrastructure before the Emergency Group Call starts.  
The terminal may wait for infrastructure acknowledge for this  
Alarm and attempt retries. Each time you press the  
Emergency button, the terminal will send an Emergency  
Alarm.  
Hot Mic (Hot Microphone) allows you to talk without pressing  
the PTT. Pressing PTT during Hot Mic ends Hot Mic  
transmission. Pressing the End soft key ends Hot Mic  
activity. If Hot Mic is disabled, then use PTT to talk.  
• Emergency Private Call (half-duplex or full-duplex)  
The terminal will start an Emergency Private Call to a pre-  
defined ID when you press and hold the Emergency button.  
If an Emergency Private Call gets modified to an Emergency  
Group Call, the terminal will enter Emergency Mode and will  
leave the Emergency Mode when the call ends.  
Changing Folder or Group  
See Group Call section on page 32.  
Entering or Exiting Emergency Mode  
Upon entry into Emergency Mode any existing call or service  
other than packet data service will be aborted or cleared  
down.  
In Emergency Mode, the terminal will automatically reject  
Phone, PABX and Private Calls, and will not monitor the  
groups in the user selected scan list. If an ATG is the  
selected group, however, the terminal will monitor the sub-  
55  
     
groups associated with the ATG. The terminal will remain in  
Emergency Mode until you exist it.  
Press and hold the Emergency button to enter  
Emergency Mode.

Making an Emergency Group Call  
While in an Emergency Group Call, you can still perform group operations  
(such as changing group/folder, searching for a group, or entering the My  
Groups folder).  
To initiate or answer a call while in Emergency Mode:  
• Press and hold PTT.  
• Wait for the talk permit tone (if configured) and talk.  
• Release PTT to listen.  
For the delivery reports, see “Sending an Emergency Alarm”  
above.  
You can also participate in an Emergency Group Call  
(initiated by others) in Emergency Mode or in a standard  
Group Call.  
Hot Microphone Feature  
If the Hot Microphone feature was programmed into your  
MTH800 by your Service Provider, you can make an  
Emergency Group Call without the need to press and hold  
the PTT.  
The following will happen upon entering Emergency Mode:  
1. The MTH800 will automatically send an Emergency  
Alarm to the dispatcher (if configured by your Service  
Provider).  
2. A Talk permit tone will be heard.  
3. The following typical display will appear:  
The microphone will stay open for a time  
period determined and programmed by  
Hot Mic On  
your Service Provider.

During this pending time the MTH800 microphone is not active until the  
Emgcy Mic On message is displayed again.  
Receiving an Emergency Group Call  
A terminal in TMO receives an Emergency Group Call to the  
selected group, associated ATG (Announcement Talkgroup),  
or scanned group. If the ATG is the currently selected group,  
the terminal will receive the Emergency Group Call to the  
group associated with this ATG. (For information on the ATG,  
see page 32.)  
When the MTH800 receives the call, the display will show  
Emgcy In Use and the caller’s identity.  
If upon entering Emergency Mode, your MTH800 receives an  
Emergency call, and Hot Microphone was enabled by your  
Service Provider, the Wait For Mic message will be  
displayed. Your MTH800 will attempt to get a talk permit.  
The caller’s voice will always sound via the speaker (unless  
an external earpiece is connected to the terminal.  
If configured by your Service Provider, the screen  
background will be red.  
Making an Emergency Private Call  
• Press and hold the Emergency button.  
• The terminal will start the call as a half-duplex or full-  
duplex call (as programmed). The Emergency ID is pre-  
defined and is not displayed.  
• Continue the call as you would do in a half-duplex or full-  
duplex call.  
58  
     
Receiving an Emergency Private Call  
• The tallker’s identity is displayed when the terminal  
receives the half-duplex call.  
• When the terminal receives the call, the display will show  
Emergency Prvt In Use and the caller’s identity.  
• If configured by your Service Provider, the screen back-  
ground will be red.  
• Continue the call as you would do in a half-duplex or full-  
duplex call.  
Modifying the Type of Call  
The infrastructure can modify on-going calls as follows:  
• Emergency Group Call to Emergency Private Call, and  
vice versa.  
• Anyone of the above to a Phone Call.  
If Hot Mic is interrupted when the modification occurs, the  
display will show the Hot Mic Ended message.  
Continue the modified call depending on the type of call.  
Emergency in DMO  
General  
You can initiate an Emergency Group Call to a group.  
You can receive an Emergency Group Call:  
• From the selected talkgroup  
• From other users within talkback range (if configured by  
your Service Provider). This is called an InterMNI call.  
• From an open group. (An open group is a super-group to  
which all DMO groups belong.)  
Emergency calls can be placed via gateway. For gateway  
settings, see the DMO section, page 43.

GPS Location Services  
Your terminal’s GPS Location feature uses information from  
Global Positioning System (GPS) satellites orbiting the Earth  
to determine the approximate geographical location of your  
terminal. The availability and accuracy of this location  
information (and the amount of time that it takes to calculate  
it) will vary depending on the environment in which you are  
using the terminal.  
For example, GPS location fixes are often difficult to obtain  
indoors, in covered locations, between high buildings, or in  
other situations where you have not established a clear  
broad view of the sky.  
SEE: IMPORTANT: Things to Keep in Mind.  
The GPS location Service can assist your Dispatcher or  
Colleagues in many ways such as more efficient deployment  
of resources or locating your terminal if you trigger your  
emergency service.  
The terminal can be configured to display location  
information on the terminal’s display or to send it over the air  
to your dispatcher where it can be displayed in control center  
(Please check with your Service Provider on the  
configuration of your terminal).  
IMPORTANT: Things to Keep in Mind  
Where adequate signals from multiple satellites are not  
available (usually because your terminal cannot establish a  
view of a wide area of open sky), the GPS feature of your  
terminal WILL NOT WORK. Such situations include but are  
not limited to:  
• In underground locations  
• Inside of buildings, trains, or other covered vehicles  
• Under any other metal or concrete roof or structure  
• Near a powerful radio or television tower  
61  
     
• When your GPS antenna is covered (for example, by your  
hand or other object) or facing the ground  
Ιn temperature extremes outside the operating limits of  
your terminal  
Even where location information can be calculated in such  
situations, it may take longer to do so. Therefore, in any  
emergency situation, always report your location to your  
dispatcher.  
Furthermore, please note that even where adequate signals  
from multiple satellites are available, your GPS feature will  
only provide an approximate location, often within 20 - 100  
meters from your actual location.  
Enhancing GPS Performance  
Sometimes the GPS feature of your terminal may be unable  
to complete a location calculation successfully. You will then  
see a message indicating that your terminal cannot see  
enough visible satellites.  
To maximize the ability of your terminal to determine a  
location fix please note the following guidelines:  
• Stay in the open. The GPS feature works best where there  
is nothing between your terminal and a large amount of  
open sky. If possible, go outside, away from tall buildings  
and foliage. While performance in a building is improved  
by moving closer to windows, glass with certain sun  
shielding films may block satellite signals.  
• Position your terminal to enhance reception. Signals from  
GPS satellites are transmitted to your GPS antenna, which  
is in your terminal antenna. Hold your terminal away from  
your body, giving the antenna clear access to satellite sig-  
nals. Do not cover the antenna area with your fingers or  
anything else.  
62  
   
• Stand still. If possible, stand still until your terminal is fin-  
ished determining your location. Moving your terminal at a  
walking pace while your terminal is calculating your  
approximate location may substantially decrease GPS  
performance.  
• In a car. When using the GPS feature in a car, position  
your terminal so that the GPS antenna has good access to  
GPS signals. Typically, the GPS antenna has best access  
to GPS signals in a car when placed near a window.  
GPS Icon  
When your terminal is receiving valid GPS location data, a  
GPS icon will be shown in the display:  
Please note, that during emergency mode, your terminal will  
not display the GPS icon even when receiving GPS location  
data. If valid GPS location data is available when you leave  
emergency mode the GPS icon will be displayed again.

terminal and remains there even when your terminal is  
powered off. You will see this information the next time you  
view the Position screen.  
If you received a terminal call or alert while attempting to  
determine your location, the Position screen will disappear,  
but your terminal will continue attempting to determine its  
location. If it is successful, the new location information will  
be displayed the next time you view the Position screen.  
GPS Testpage  
Satellite Almanac Data  
Government officials maintains an almanac of data about  
where GPS satellites are as they orbit the Earth. This  
information is available to your terminal. Keeping your  
satellite almanac up to date helps your terminal determine  
your location more quickly.  
The almanac contains information about the location of  
satellites, their operational status, and other satellite  
information.  
65  
 
In most cases, your terminal will be able to get a fix in strong  
satellite signal conditions with outdated almanac data, but it  
may take longer.  
When you make an Emergency Call, your terminal does not rely upon the  
almanac to determine your location.

Contacts  
General  
Contacts stores Private, Phone, and PABX numbers. Each  
Contacts entry can store several numbers. A Contacts entry  
contains:  
• A name—A name is required if you are storing more than  
one number to the entry; otherwise, it is optional. Typically,  
this is the name of the person whose contact information is  
stored in the entry.  
• A Contacts type—Each number stored must be assigned a  
Contacts type.  
• A number—Each Contacts entry must contain a number.  
This may be any type of phone number and Private ID.  
• A Speed Dial number — When you store a phone number,  
it is assigned a Speed Dial number. You can accept the  
default Speed Dial number or change it.
