Operation

All GP300 radio models have an internal

squelch setting which is adjusted at the factory.

The squelch level setting is not a user-operated

control; however, it may be reprogrammed

through the Radio Service Software available at

your local Motorola dealer.

To Transmit

Set the channel selector to the desired channel position.

2. Do not interrupt another user. Listen for activity on your

channel. If the channel on which you are transmitting is

programmed to receive PL/DPL, momentarily depress

the monitor button to listen for channel activity. The

channel must be clear before transmitting.

3. While holding the radio in a vertical position with the

speaker-microphone grille two to three inches from

your mouth, press the PTT button on the side of the

radio and speak slowly and clearly into the grille area.

When ﬁnished transmitting, release the PTT button to

receive. When the PTT button is depressed the LED

glows red and remains on for the entire length of the

transmission, and turns off when the PTT button is

released.

When the PTT button is depressed (and as long

as the PTT button remains depressed), the bat-

tery voltage is automatically monitored and if

the voltage is low, the LED ﬂashes red to alert

you of the low battery condition. In addition, a

double alert tone is sounded when the PTT is

released.

The power to the radio should be turned OFF

when an audio accessory with a microphone is

to be connected to the radio. Such items

include Headsets w/mics, Speaker-Micro-

phones and Surveillance Microphones. Follow-

ing this procedure ensures proper operation of

the PTT button and other controls.
