Miscellaneous Settings

Time-Out Timer

The "Time-Out Timer" (TOT) feature is designed to force the transceiver into the
"receive" mode after a pre-set time period of continuous transmission (the default
is 6 minutes). This feature prevents your transceiver from transmitting a "dead
carrier" for a long period of time in the event that the microphone PTT switch is
accidentally locked in the "TX" condition.
The Time-Out Timer's "switch-to-receive" time may be adjusted, in one minute
increments, for any period between 1 and 60 minutes.
To change the default (6 minute) time setting:
1. Press and hold in the
knob to select "3 5 T O T ."
2. Press either the
tween 1 and 6 0 minutes, or O F F ).
3. Press and hold in the
exit to normal operation.

Automatic Power-Off

The "Automatic Power-Off" (APO) feature will turn the radio completely off after
a user-defined period of PTT or key/button inactivity. If you do not press any
front panel keys or buttons, do not rotate the M
microphone's keys and buttons, do not transmit, and so long as the transceiver is
not scanning or engaged in priority monitoring, the radio will shut itself off after
the specified time period. This feature is useful in minimizing battery drain in a
mobile installation if you forget to turn the transceiver off when you leave your
vehicle.
To activate the APO feature:
1. Press and hold in the
knob to select "0 3 A P O ."
2. Press either the
(between 1 and 1 2 hours, or O F F ).
3. Press and hold in the
exit to normal operation.
