Transmitter Time-Out Timer ( TOT )
The TOT feature provides a safety switch which limits
transmission to a pre-programmed value. This will pro-
mote battery conservation by not allowing you to make
excessively-long transmissions, and in the event of a stuck
PTT switch (perhaps if the radio or a Speaker/Mic is
wedged between aircraft's seats) it can prevent interfer-
ence to other users as well as battery depletion. As config-
ured at the factory the TOT feature is set to OFF, and here
is the procedure for activating it:
Press the key, then press the
the Menu ("SET") mode.
