Using the Time-Out Timer
This feature turns off your radio’s transmitter. You cannot
transmit longer than the preset timer setting.
If you attempt to do so, your 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 3 to 120 seconds, in 15-second intervals,
or it can be disabled entirely for each radio mode, by a qualified
radio technician.
Note:
You will 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 short, low-pitched warning tone, the
transmission is cut-off, and the LED goes out until you
release the
PTT
button.
2
Release the
PTT
button. The timer resets.
3
Press the
PTT
button to re-transmit. The time-out timer
restarts and the LED lights up solid red.
