General Information
General Information
This user guide covers the operation of the GP600
Series portable radios used on MPT1327 Trunked
Radio Systems. Please note that not all types of call
may be possible on your system, please contact
your network manager for further information on the
calls available on your particular system.
This user guide describes the operation of radios
with and without a keypad/display. On radios
without a keypad/display the different types of call
described can only be selected via the Shortform
Dial Position Selector or the Base Call Button.

Radio Care
Avoid any physical abuse of the radio such as
carrying the radio by its antenna.
Wipe the battery contacts with a lint free cloth to
remove dirt, grease or any other material which may
prevent a good electrical contact of the battery
terminals to the radio.
The accessory connector is fitted with a protective
cap which should be left in place when the
connector is not in use.
If cleaning is required, the radio housing should be
cleaned with a cloth dampened with clean water and
a mild liquid soap solution.

English

Caution:

The use of chemicals such as detergents, alcohol,

aerosol sprays, and petroleum products may be
harmful and damage the radio housing.

Safety Information
During normal use, this radio will subject you to
radio energy substantially below the level where any
kind of harm is reported.
DO NOT however hold the radio
with the antenna very close to, or
touching exposed parts of the
body, especially the face or eyes,
while transmitting. The radio will
perform best if the microphone is 5 to 10cm

Getting Started
Getting Started
Turning the Radio On/Off

The Display
The display, showing icon locations, is as follows:
LO

Turn the radio on by rotating the combined ON/OFF/

VOLUME control clockwise. The radio then enters a
self test routine. During the test the display will be
activated, the self test tone will sound, and the LED
will light green. If the radio fails the self test a
continuous low tone will sound and the LED will
flash red or yellow. The radio is turned off by rotating
the volume control anticlockwise past the click stop.
Note: If the radio fails the self test routine, consult
your dealer.
When the self-test is complete the radio displays its
identity number (keypad/display radio only).
After this the radio will scan for a radio system with
the LED on the top of the radio flashing and the
scanning icon
lit.
When the radio is registered on a system, the green
LED is extinguished and the scanning icon is
replaced by the registered icon
. The display
shows the radio identity number on the right of the
display. This is known as the IDLE state.

In the IDLE state the display shows the radio identity

number. When making a call, the display will show
the called number on the left and the transmit timer
on the right, see Outgoing calls:

The display is similar when using DTMF dialling

except that the digits scroll to the left leaving the last
four digits displayed:

When a call is received the display shows the calling

number on the right, and possibly a status number.
When interrogating the call in absence stack the
display also shows the position in stack on the left:

When entering a # , a or S (for status) the

display shows them as, respectively:

The radio must be in this state before you can make

or receive a call.

Outgoing Calls
Outgoing Calls

Dedicated Calls

The radio is capable of making a variety of calls

including calls to individual radios or group of radios.
The radio can make calls by Shortform Dialling or
Dedicated Calls. Keypad radios can also make
calls using Manual Dialling.

Hold the Base Call Button down for short period to

make a call to a preprogrammed number. The
number will then be displayed and the call initiated
to the requested number.

When making a call note that the radio has a

maximum transmit timer. This appears on the right
of the display, replacing the radio identity number.
This prevents excessive use on the speech channel
by returning the radio to the IDLE state, (effectively
cancelling the call). Ten seconds before the radio
returns to the IDLE state the keyclick tone sounds.

Manual Dialling (Keypad Radios only)

Shortform Dialling
When the radio is in the IDLE state shortform
dialling may be used. This allows quick access to up
to 16 preprogrammed numbers, using the shortform
dial position selector. When the required number is
selected the call is sent by either pressing the PTT
button or # key.
If the shortform dial selector is moved, but no call
request is sent, the display is held until the tone H
sounds. The radio then reverts to the IDLE state.
Note: When using the keypad radio, if the shortform
dial number is displayed, it may be edited as
described in the Keypad Edit section.

English

Outgoing Calls

To make a call enter the telephone number, the

identity of the radio or group of radios via the
keypad, e.g. 210 followed by # or PTT.
Keypad Edit (Keypad Radios only)
Any numbers shown in the display may be changed
before a call is initiated. Enter this mode by pressing
. Shortform or dedicated calls may then be
altered. Press
again to delete the last digit and
enter a different number. If
is pressed during a
call, the call will end. If
is pressed from the IDLE
state tone H sounds.
Last Number Redial
The last number called from the radio is stored in
the memory of the radio. For status calls, only the
called number will be stored, not the status
message.

Incoming Calls
Incoming Calls
There are two types of systems that the radio may
be used on, Off Air Call Set Up (OACSU) and Full
Off Air Call Set Up (FOACSU).
If you are in any doubt about which system you are
operating on, consult your network manager.

Receiving a call on an OACSU system When the radio is called tone D will sound and the
LED and display flashes. This will then be followed
by tone B.
Receiving a call on an FOACSU system When the radio is called tone E will sound and the
LED and display flashes.
Press either the PTT or # key to accept the call.
Tone D will sound until a speech channel is
allocated, then tone B sounds.
Note: The system may have a limited call time and
the call may be terminated automatically if this call
time is exceeded.
Call In Absence
Call in Absence is only available for keypad/display
radios. If a call is not answered within a set amount
of time, the call is stored by the radio. It is not
possible to store group calls.

Up to 5 calls can be stored. If the same radio calls

more than once, the call is only stored once. When 5
calls have been stored by the radio the sixth call
received overwrites the first.
When a call has been stored by the radio, tone G
sounds every ten seconds. The call in absence icon
will be lit to indicate there is a call in the stack.
To view/interrogate the calls in the stack press the
up or down scroll key
or
and then use these
keys to view the numbers in the stack.
The most recent call stored by the radio is displayed
first. Select the up/down scroll keys to display calls
in the stack. If the stack is empty tone H sounds.
To exit the call in absence interrogate mode press
the keypad edit button
.
Press either the PTT or # key to make a call. On
a successful call set-up, the entry is automatically
deleted from the stack. Unanswered calls may be
deleted from the stack at any time by pressing the
Clear Button.
Note: The calls in the stack are deleted when the
radio is turned off. It is not possible to call back
status calls.

DTMF Operation
Emergency Calls

DTMF Operation

An emergency call allows you the highest form of

priority calling and normally takes precedence over
all other calls. An emergency call is indicated either
by pressing the Base Call Button or by dialling the
number, prefixing the required number by 9 .
The call is then initiated as previously described.

DTMF means Dual Tone Multi Frequency (the same

tones as a telephone) and is used when the radio is
required to operate in a radio system with an
interface to telephone systems. DTMF dialling is
only available on keypad radios.

Priority Calls
A priority call allows you to gain priority over other
users of the system when requesting a call. A
priority call is indicated by pressing the Base Call
Button or by prefixing the required number by
8 . The call is then initiated as previously
described.
Broadcast Calls
A broadcast call allows you to make calls to groups
of radios. There is, however, no indication that any
units have received the call.
A broadcast call is indicated by pressing the Base
Call Button or by prefixing the required group
number by 1 1 . The call is then initiated
as previously described.

Battery Tips

Do not force discharge nickel cadmium batteries

Do initialize new batteries that have been stored for

beyond one volt per cell. Excessive deep discharge

can significantly reduce battery life.
Do not use chemical cleaners to clean batteries.
Clean batteries only with a mild soap and dry
thoroughly with a cloth.

prolonged periods by charging overnight (16 hours).

Do charge batteries every 6 months during prolonged

storage.

Do use a battery for at least 4 hours prior to

recharging. Remember, each time the battery is

charged, one cycle of life is used, and a battery has a
limited number of life cycles.
Do allow the battery to reach room temperature (at
least 1 hour) before placing it in the charger. Charge
Temperature Range: +5C to +50C.
Do take batteries out of a charger when they are fully
charged. Batteries allowed to remain in the charger for
extended periods lose valuable cycle life.
Do choose the right battery for every application.
Motorola offers a variety of batteries with different
sizes, capacities, and environmental use conditions.
Do dispose of used batteries properly and never
dispose of them in fire.
Do not charge a hot battery; if a battery is hot at the
beginning of charge, charge efficiency will be greatly
reduced. Nickel cadmium batteries are most efficiently
charged at room temperature (25C).
Do not fast charge a cold battery. Charging a cold
battery can cause excessive internal pressures, cell
leakage, and catastrophic failure.

Remember......Conserve Battery Life Cycles!

Any secondary battery has a limited number of cycles;
each time the battery is charged and discharged,
one cycle of battery life is used.
