 (ToT)
The Time-out Timer is used to prevent any caller from using a channel for an 
extended period of time.
If you continuously transmit for a period of time that exceeds the programmed 
time, the transceiver will stop transmitting and an alert tone will sound.  To stop 
the tone, release the microphone 
PTT switch. Your dealer can program the TOT 
time in the range of 5 seconds to 20 minutes.
If programmed by your dealer, a pre-alert tone will sound before the timer expires.  
Also, if programmed by your dealer, you may have to wait for a short duration 
before you can continue to transmit.  If you press the microphone 
PTT switch 
before the timer has been reset, an alert tone will sound and the transceiver will 
not enter transmit mode.

The compander can be programmed only for specific FM channels.  If it has been 
programmed by your dealer, transmitted signals are compressed before being 
sent and received signals are expanded when they arrive.
•  Your dealer must set the compander for both the transmit side and the receive side in 
order for the compander to operate.
This background feature allows higher clarity of signals, avoiding excessive noise.  
This feature is not used on digital channels, as they are not susceptible to noise 
and interference.
