Air Call Set Up (FOACSU). If you are in doubt about
which system you are operating on, please consult
your dealer.

LED flashes. This will then be followed by tone B.

and the LED flashes.
Press the PTT to accept the call. Tone D will sound
until a speech channel is allocated, then tone B

the call may be terminated automatically if this
call time is exceeded.
