TIME-OUT TIMER
The Time-out Timer limits the time of each transmission
to a maximum of 3, 5, or 10 (default) minutes. Just
before the transceiver stops the transmission, a warning
beep sounds. This function is necessary to protect the
transceiver from thermal damage and can therefore not
be turned OFF.
