AUTOMATIC POWER OFF (APO)

Automatic Power Off is a background function that monitors whether any keys have been pressed, or whether any control has been turned. After the predetermined time passes with no operations, APO turns OFF the power. However, 1 minute before the power turns OFF, “APO” blinks and a series of warning tones sound.

Access Menu 1–2–2 (APO) and select 30 minutes (default), 60 minutes, or OFF.

Note:

If a signal is received while APO is ON, the timer begins counting again from 0.

The APO timer does not operate while Tone Alert or any scan is being used.

BATTERY SAVER

Battery Saver repeats switching the receive circuit ON and OFF at a certain interval when no signal is present and no key is pressed for approximately 10 seconds.

This function becomes passive whenever a signal is received or any key is pressed.

Access Menu 1–2–1 (BAT SAVER) to select the desired interval (power OFF duration). The default is 1.0 second.

The selectable intervals are 0.2, 0.4, 0.6, 0.8, 1.0, 2.0, 3.0, 4.0, and 5.0 seconds plus OFF; selecting OFF switches the function OFF.
