ISCELLANEOUS
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 the [ SET ] key momentarily to enter the Set mode.
2. Rotate the "Main" band DIAL knob to select Menu #42 (TOT).
3. Press the "Main" band DIAL knob momentarily, then rotate the "Main" band DIAL knob
to select the desired interval (between 1 and 30 minutes), or OFF.
4. Press and hold in the "Main" band DIAL knob for 1/2 second to save the new setting and
exit to normal operation.
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 trans-
mit, 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 the [ SET ] key momentarily to enter the Set mode.
2. Rotate the "Main" band DIAL knob to select Menu #1 (APO).
3. Press the "Main" band DIAL knob momentarily, then rotate the "Main" band DIAL knob
to set the desired "switch-off" time (between 1 and 12 hours in 0.5 hours increments), or
OFF.
4. Press and hold in the "Main" band DIAL knob for 1/2 second to save the new setting and
exit to normal operation.
