Time-Out Timer (Tot); Automatic Power-Off (Apo) - Yaesu FT-2980R Operating Manual

Miscellaneous Settings

Time-Out Timer (TOT)

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 3 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 to 1/3/5/10 minutes, or
Off.
To change the default (3 minutes) time setting:
1. Press and hold in the [ MHz ( SET )] key for one second,
then rotate the DIAL knob to select "53 TOT".
2. Press the [ MHz ( SET )] key, then rotate the DIAL knob to
select the desired interval (1/3/5/10 minutes), or OFF.
3. Press and hold in the [ MHz ( SET )] key for one second to
save the new setting and exit to normal operation.
When your transmission time is within 10 seconds of the Time-Out Timer ex-
piration, an Alert bell will provide an audible warning from the speaker.

Automatic Power-Off (APO)

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, rotate the DIAL knob, 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. The available selections for the time before
power-off are 0.5/1/3/5/8 hours, as well as APO Off. 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 [ MHz ( SET )] key for one second,
then rotate the DIAL knob to select "1 APO".
2. Press the [ MHz ( SET )] key, then rotate the DIAL knob to
select the desired "switch-off" time or OFF.
3. Press and hold in the [ MHz ( SET )] key for one second to
save the new setting and exit to normal operation.
If there is no action by you within the time interval
programmed, an Alert bell will provide an audible warning from the speaker within 1
minute of the APO Timer expiration, then the microprocessor will shut down the radio
automatically.
