9.5 TRANSMIT TIME-OUT TIMER (TOT)
When the PTT switch on the microphone is held down, transmit time is limited
to 5 minutes. This limits unintentional transmissions due to a stuck microphone.
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.
NOTE
Once the transmitter is shut down by the TOT, transmission on the channel
is only allowed 10 seconds after the shutdown.
