•COLOR
(•F + short press)
Press one time •F key and short press •COLOR key to alternate between 3 colors :
Orange -> Green -> Blue
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 transmission (using the PTT key or VOX) is more than 5 minutes, CHANNEL and
starts blinking, the transmission ends.
The TX time out tone will sound until the PTT key is released.
ANL FILTER (Automatic Noise Limiter)
The transceiver is equipped with an automatic filter which reduces back ground
noises and some reception interferences in AM.
A) DC-POWER TERMINAL (13,8 V / 27,6 V)
B) ANTENNA CONNECTOR (SO-239)
C) EXTERNAL SPEAKER JACK (8 Ω, Ø 3,5 mm)
D) PA SPEAKER JACK (8 Ω, Ø 3,5 mm)
E) JACK FOR OPTIONAL VOX MIKE (Ø 2.5 mm)
is displayed and release to listen
