a) )Choosing antenna:
- For 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.
- For 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).
INSTALLATION
WHERE AND HOW TO MOUNT YOUR MOBILE CB RADIO
1.
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.
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 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 communications(connector ext.
SP situated on the back panel: D). Ask your dealer for advice on
mounting your CB radio.
ANTENNA INSTALLATION
2.
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
1.
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.
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
2.
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 (Full-anti clockwise)
e) Adjust the volume to a comfortable level
f ) Go to channel 20 E by using either the [
] or [
] key.
ADJUSTMENT OF SWR(standing wave ratio)
3.
WARNING:
This must be carried out when you use your CB radio
for the first time (and whenever you re-position your antenna). The
adjustment must be carried out in an obstacle-free area.
＊
Adjustment should be operated with external SWR meter.
a)To connect the SWR meter
Connect the SWR meter between the CB radio and the antenna
as close as possible to the CB radio (use a maximum of 40cm
cable)
b) To adjust the SWR meter
-Set the CB to channel 20 E band in FM
-put the switch on the SWR meter to position CAL or FWD
-Press the <<Push-To-Talk>> switch on the microphone to
transmit
-Bring the index needle to ▼ by using the calibration key
- Change the switch to position SWR (reading of the SWR level)
The reading on the meter should be as near as possible to 1. If
this is not the case, re-adjust your antenna to obtain a reading
as close as possible to 1.( An SWR reading between 1 and 1.8
is acceptable).
- It will be necessary to re-calibrate the SWR meter after each
adjustment of the antenna.
Your CB is now ready for use.
