(TOT)
The purpose of the Time-out Timer is 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 PTT switch.
Your dealer can program the TOT time in the range of
15 seconds to 10 minutes.
