WARNING
Please install the antenna (connect to the location (B) in the back panel of the radio) and
set the SWR (Standing Wave Ratio) before transmitting. Otherwise it may result in des truc -
tion of the power amplifier, which is not covered by the guarantee.

INSTALLATION
Where An How To Mount Your Mobile CB Ra io
A) You should choose the most appropriate setting from a simple and practical point of
view.
B) Your CB radio should not interfere with the driver or the passengers.
C) Remember to provide different wires for the passing and protection (e.g.: power,
antenna, accessory cabling) so that they do not in any way interfere with the driving of
vehicles.
A) To install your equipment, use the cradle (H) and the self-tapping screws (E) provided
(drilling diameter 4 mm). Take care not to damage the vehicle’s electrical system while
drilling the dash board.
E) Do not forget to insert the rubber joints (G) between the CB and its support as these
have a shock-absorbing effect which permits gentle orientation and tightening of the
set.
F) Choose where to place the microphone support and remember that the microphone
cord must stretch to the driver without interfering with the controls of the vehicle.
G) As the transceiver has a frontal microphone socket, it can be set into the dash board.
You will need to add external loud speaker to improve the sound quality of communi -
cations(connector ext. SP situated on the back panel (D).
Ask your dealer for advice on mounting your CB radio.

Antenna Installation
a) Choosing antenna:
– or CB radios, the longer the antenna, the better its results. Your dealer will help you
with your choice of antenna.
b) Mobile antenna:
– Must be fixed to the vehicle where there is a maximum of metallic surface (ground
plane), away from windscreen mountings.
– If you already have a radio-telephone antenna installed, the CB antenna should be
higher than this.
– There are two types of antenna: Pre-regulated antenna which should be used on a good
ground plane (e.g. car roof or lid of the boot), and adjustable antenna which offer a much
larger frequency range and can be used on a smaller ground plane.
– or an antenna which must be fixed by drilling, you will need a good contact between
the antenna and the ground plane. To obtain this, you should lightly scratch the surface
where the screw and tightening star are to be placed.
– Be careful not to pinch or flatten the coaxial cable (as this runs the risk of break down
and/or short circuiting).
– Connect the antenna to location (B).
c) Fixed antenna:
A fixed antenna should be installed in a space as spacious as possible. If it is necessary
for you to fix the antenna to a mast, you need to keep it as per the requirements of the
laws in force (please turn to professional advice).

Power Connection
This is protected against an inversion of polarities. However, before switching it on, you
are advised to check all the connections. Your equipment must be supplied with a con ti -
nued current of . 2 volts (A). Today, most cars and lorries are negative earth. You can
check this by making sure that the negative terminal of the battery is connected either to
the engine block or to the chassis. If this is not the case, you should consult your dealer.
WARNING: Lorries generally have two batteries to supply a voltage of 24 volts, in which
case it will be necessary to insert a 24/. 2 volt converter into the electrical circuit. The
following connection steps should be carried out with the power cable disconnected
from the set
a) Check whether the battery is of . 2 volts.
b) Locate the positive and negative terminals of the battery (+ is red and – is black).
Should it be necessary to lengthen the power cable, please use the same or a superior
type of cable.
c) It is necessary to connect your CB to a permanent (+) and (–). We advise you to connect
the power cable directly to the battery (as the connection of the CB cable to the wiring
of the car-radio or other parts of the electrical circuit may, in some cases, increase the
possibilities of interference).
d) Connect the red wire (+) to the positive terminal of the battery and the black (–) wire to
the negative terminal of the battery.
e) Connect the power cable to your CB radio.
WARNING: Never replace the original fuse (5A) by one of a different value.
Basic Operations
a) Connect the microphone.
b) Check the antenna connections.
c) Turn the set on by turning the volume knob clockwise.
d) Turn the squelch knob to minimum ( ull-anti clockwise).
e) Adjust the volume to a comfortable level.
f) Go to channel 20@EC by using either the [∫] or [√] key.
