ONLY.

MICROPHONE

The mobile radio uses a dynamic microphone with a

built-in transistorized pre-amplifier. The microphone is

housed in a sturdy case and the extendable coiled cord plugs

into a jack provided at the back of the radio. The

microphone is secured to the radio by means of a strain

relief hook on the microphone cable.

HOOKSWITCH

A hookswitch is provided with the radio to hold the

microphone. Removing the microphone from the hookswitch

disables the Channel Guard, enabling the operator to

monitor the channel before sending a message. Removing

the microphone while in the SCAN mode, will also disable

SCAN until the microphone is placed back into the

hookswitch.

CHANNEL GUARD

Channel Guard provides a means of restricting calls to

specific radios through the use of a continuous tone or

digitally coded squelch system (CTCSS or DCG). Tone

frequencies range from 67.0 Hz to 210.7 Hz. 33 standard

tones and 104 unique digital codes are available.

CARRIER CONTROL TIMER

The Carrier Control Timer turns off the transmitter after

the microphone push-to-talk switch has been keyed for a

pre-programmed time period. The timer can be

programmed to time out and sound an alert tone in 30-

second increments up to 7.5 minutes.

EXTERNAL SPEAKER (OPTIONAL)

An optional 4-Watt, 4-ohm external speaker is available

for use with the radio. The speaker is supplied with a

mounting bracket and mounting hardware. The speaker

leads connect through connector J701 on the back of the

radio (refer to applicable Installation Manual).

PROGRAMMING

The EEPROM allows the radio to be programmed or

reprogrammed as needed to adapt to changing system

requirements. RF frequencies, Channel Guard tones, digital

codes, and CCT can be reprogrammed. The EEPROM is

programmed through the radio MIC connector (J701) using

an IBM compatible PC and special cable. Programming

instructions are provided in the respective programming

manual.

OPERATION

This section provides a description of the Control and

Indicator functions as well as the basic procedures for

transmitting and receiving messages. Complete operating

instructions for the radio are provided in the respective

Operator’s Manual.

CONTROLS

The radio control panel contains the VOLUME control,

the POWER on/off switch, the MONITOR switch and the

CHANNEL select switch. The switch functions are as

follows:

POWER

A momentary type switch to turn the

radio on or off. Press once to turn the

radio on; press again to turn the radio

off. Power ON is indicated by an

illuminated channel number on the

system module.

VOLUME

Two momentary type switches to adjust

the volume. Press and hold the MAX (up

arrow) to increase the volume. Press and

hold the MIN (down arrow) to decrease

the volume.

MONITOR

A momentary type switch to allow you to

monitor the selected channel before

transmitting a message. It disables

Channel Guard and squelch and will

allow you to hear noise if the channel is

not busy. This may be convenient when

setting the volume to the desired

listening level.
