5.3 TRANSMIT TIME - OUT TIMER (TOT)

When the PTT switch on the microphone is held down, transmit time is
limited to 5 minutes. This prevents unintentional transmissions. About 10
seconds before automatic transmitter shutdown, a warning beep will be
heard from the speaker(s). The transceiver will automatically go to receive
mode, even if the PTT switch is continually held down. Before transmitting
again, the PTT switch must first be released and then pressed again.
