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 41.
7) UP AND DOWN KEYS
Both keys allow to go up and down the channels by a brief pressure. A con-
tinuous pressure 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.
FREQUENCY BAND SELECTION
(configuration: E; d; EU;EC; U; PL)
The frequency bands have to be chosen according to the country of use.
Don't use any other configuration. Some countries need a user's licence.
See table on page 43.
Proceeding
a) Switch off the CB radio.
b) Press and hold the PTT button of the microphone and then switch on CB radio.
The letter corresponding to configuration is blinking.
c) To choose the configuration turn the channel selector rotary knob or use
buttons UP/DN of the microphone.
d) Press the PTT button of the microphone one second until the letter correspond-
ing to configuration stop blinking to confirm the configuration.
e) Switch the CB radio off in order to save.
See the configurations/ frequency bands table at pages 39 ~ 42.
A) DC-POWER TERMINAL (13.2 V)
B) ANTENNA CONNECTOR (SO-239)
C) EXTERNAL SPEAKER JACK (8 Ω, Ø 3.5 mm)
