This prevents prolonged (unintentional) transmissions. About 10 seconds be-
fore automatic transmitter shutdown, a warning beep sounds from the speaker.
The transceiver automatically switches to the receiving mode, even if the PTT
switch is held down. Before transmitting again, the PTT switch must first be
released, then wait 10 seconds and then pressed again. This Time-Out-Timer
(TOT) prevents a continuous transmission that would result from an acciden-
tally stuck PTT switch.
