Using the Time-Out Timer
When and where to use: This feature turns off the transmitter of your radio. You cannot transmit longer than
the preset timer setting.
If you attempt to do so, the radio automatically stops your transmission, and you hear a talk-prohibit tone.
The timer is defaulted at 60 seconds, but it can be preprogrammed from 15 to 465 seconds, in 15-second
intervals, or it can be disabled entirely for each radio mode, by a qualified radio technician.
NOTE: You hear a brief, low-pitched, warning tone four seconds before the transmission times out.
Procedure:
1. Hold down the PTT button longer than the preprogrammed time.
You hear a continuous talk prohibit tone. The transmission is cut off and the LED goes out.
2. Release the PTT button.
The timer resets.
3. To re-transmit, press the PTT button.
The time-out timer restarts and the LED lights up solid red.
