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 destruction of the power amplier, which is not covered by
the guarantee

INSTALLATION
1.
WHERE AND HOW TO MOUNT YOUR MOBILE RADIO
a) You should choose the most appropriate setting from a simple and
practical point of view
b) Your 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.
d) 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 radio 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 communications (connector ext. SP
situated on the back panel [D].
Ask your dealer for advice on mounting your radio.

ANTENNA INSTALLATION
a) Choosing antenna:
-For mobile radios, the longer the antenna, the better its results.
Your dealer will help you with your choice of antenna.
b) Mobile antenna:
-Must be xed 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.
-For an antenna which must be xed 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 atten 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 x 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 continued current of 12 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 24/12 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 12 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.
