11) LOCK
Allows to lock all the keys on the front panel and the rotary knob. An error beep
sounds when a key is used and the LOCK function is activated. A short press on
LOCK activates/deactivates the LOCK function.
the function is activated.
Transmission (microphone or vox) and reception remain active.
12) 6 PIN MICROPHONE PLUG
The plug is located on the front panel of the transceiver and makes the setting of
the equipment into the dashboard easier.
See cabling diagram page 52.
13) PTT
Transmission key, press to transmit a message,
to an incoming communication.
TOT (Time Out Timer)
If the PTT key is pressed for more than 5 minutes, CHANNEL and
the transmission ends.
The TX time out tone will sound until the PTT key is released.
