Time-out Timer 
Time-out Timer is used to prevent one from using the same channel for a long time and to 
prevent the radio from damage due to continuous transmission. 
If the transmission exceeds preset time (it’s set by your dealer), transmission will be 
stopped and a beep will sound. To stop the beep tone, release PTT. Press PTT again to 
transmit. 

TOT (Time-out Timer) Reset Time 

When this feature is disabled, TOT is immediately reset after transmission stops. When 
enabled, TOT won’t reset until preset time (it’s set by your dealer) elapses, even if 
transmission has stopped. 

TOT Rekey Time 

The feature is used to set the duration until transmission is allowed after returning to 
receive by TOT. When enabled, transmission will be prohibited until preset time elapses 
(it’s set by your dealer).   

TOT Alert Time 

This timer can be set by your dealer from 1 to 255 seconds in 1 second step. When this 
feature is enabled, the radio will call an alert at the set time. Transmission will be 
prohibited by TOT after this time. 

Battery Save 
When there is no activity on the channel and no operation is performed for 10 seconds, 
Battery Save feature is turned ON.  When a signal is received or an operation is 
performed, Battery Save feature is turned OFF automatically. 
 
Low Battery Alert 
Low Battery Alert alerts you to recharge or replace the battery. 
During transmission, when the battery voltage goes below a preset value, the light will 
flash red. When the alert tone sounds, the radio stops transmitting. Please recharge or 
replace the battery. 

Monitor 
Press and hold Monitor key to monitor activities on the current channel. This operation is 
especially useful for adjusting volume level or receiving a weak signal. 
The light will glow green while the Monitor key is held down.
