The “Time-Out Timer” (TOT) feature is designed to force the transceiver into the “receive”
mode after a preset 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 30 minutes.
To change the default (6 minute) time setting, use the following procedure:
1. Press and hold in the [
BAND ( SET )] key for 1/2 second to enter the Set mode.
2. Rotate the DIAL knob to select Menu #45 (
TOT
).
3. Press the [
BAND ( SET )] key momentarily, then rotate
the DIAL knob to select the desired interval (between 1
and 30 minutes), or OFF. You will hear a beep, while
rotating the
DIAL knob, as you pass the default six-
minute selection.
4. Press the [ BAND
(
SET
)] key momentarily to save the new setting, then press and hold in
the [
BAND ( SET )] key for 1/2 second to exit to normal operation.
When the TOT Timer reaches 10 seconds before the TOT shut-down time, a ringer sounds
to alert you to the impending shut-down.

The “Automatic Power-Off” (APO) feature will turn the radio completely off after a user-
defined period of
PTT switch or key/button inactivity. If you do not press any front panel
keys or buttons, rotate the DIAL knobs or use the microphone’s keys and buttons, or 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, use the following procedure:
1. Press and hold in the [
BAND
(
SET
)] key for 1/2 second to enter the Set mode.
2. Rotate the DIAL knob to select Menu #1 (
APO
).
3. Press the [ BAND
(
SET
)] key momentarily, then rotate
the DIAL knob to set the desired “switch-off” time (be-
tween 0.5 and 12 hours in 0.5 hours increments), or OFF
(the default selection).
4. Press the [ BAND
(
SET
)] key momentarily to save the
new setting, then press and hold in the [ BAND
(
SET
)] key for 1/2 second to exit to
normal operation.
