11) Transmitter Time-Out Timer (TOT---MENU 11)
Functions: the TOT feature provides a safety switch which limits transmission to a
pre-programmed value. This will promote battery conservation by not
allowing you to make excessively-long transmissions, and in the event of
a stuck PTT switch it can prevent interference to other users as well as
battery depletion.
Enter Menu 11
12) Busy Channel Lock-Out (BCLO---MENU 12)
Functions: the BCLO feature prevents the radio's transmitter from being activated if a
signal strong enough to break through the "noise" squelch is present. On a
frequency where stations using different CTCSS or DCS codes may be
active, BCLO prevents you from disrupting their communications
accidentally (because your radio may be muted by its own tone decoder).
Enter Menu 12
OFF: Disable BCLO feature.
WAVE: the radio's PTT will be prevented only if the frequency is busy used.
CALL: the radio's PTT will be prevented only the frequency and tone coder is the same.
13) Transmit Over Beeper (ROGER---MENU 14)
Functions: sending a beeper to inform the receiver TX is over.
