When the TOT (Timeout Timer) function is switched on, the radio will automatically return 
to the reception mode after a prescribed time has passed in the transmission mode. A 
notification beep will sound about 10 seconds before the radio returns to the reception 
mode. This can help to prevent unintended radio waves from being sent out by mistake 
and the battery from being used up.
