7.4 TRANSMIT TIME-OUT TIMER (TOT)
When the
PTT
button 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
button is continually held down. Before transmitting again, the
PTT
button
must first be released and then pressed again.
NOTE
Once the transmitter is shut down by the TOT, transmission to the last
channel is only allowed 10 seconds after the shutdown.
