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 (
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.

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.
is
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.
