3. POWER CONNECTION
Your RADIO 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. 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 radio to a permanent (+) and (-).
We advise you to connect the power cable directly to the battery (as the
connection of the 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 radio.

4. BASIC OPERATIONS TO BE CARRIED OUT BEFORE USING YOUR
SET FOR FIRST TIME (without transmitting or using the <<Push-To-
Talk>> switch on the microphone)
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
e) Adjust the volume to a comfortable level
f) Go to channel 20@D band by using either the UP or DN key on the
microphone or the rotary knob.
5. ADJUSTMENT OF SWR (Standing Wave Radio)
WARNING: This must be carried out when you use your radio for the first
time (and whenever you re-position your antenna). The adjustment must be
carried out in an obstacle-free area.
Adjustment with a built-in SWR meter or external SWR meter
a) To connect the SWR meter
Connect the SWR meter between the radio and the antenna as close as
possible to the radio (use a maximum of 40cm cable).
b) To adjust the SWR meter
- Set the radio to channel 20@D 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
- 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.

by using the calibration key.
