10.3 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.
When a transmission was shut down by the TOT, the GX1100S can not
transmit afterwards for 10 seconds.
