Using the Time-Out Timer
UTILITIES
This feature turns off your radio’s transmitter. 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 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.
