5) MODE:
Use this key to select AM or FM. The modulation mode must correspond with
that of the person with whom you communicate.
A/ Amplitude Modulation (AM) is for communications in areas where there
are obstacles and over medium distances.
B/ Frequency Modulation (FM) is for nearby communications in flat, open
areas. It gives better quality of communication (squelch adjustment needs
more finesse).
6) 6-PIN MICROPHONE PLUG:
This plug is situated on the front panel, thereby making it easier to set the
equipment into the dashboard. See the cabling diagram on page 43.
7) UP AND DOWN KEYS:
Both keys allow to go up and down the channels by a brief pression. A
continuous pression allows to ascend five channels per second.
8) PTT (push to talk):
Depress this knob to transmit a message and release to listen to an incoming
communication.
A) DC-POWER TERMINAL (13,2 V)
B) ANTENNA CONNECTOR (SO-239)
C) EXTERNAL SPEAKER JACK (8 W, Ø 3,5 mm)
