WARNING: 

Never replace the original fuse (10A) by one of a different 

value.

BASIC OPERATIONS TO BE CARRIED OUT BEFORE USING 

41 

YOUR SET FOR THE FIRST TIME 

(without transmitting or using 

the <<Push-To-Talk>> switch on the microphone)

ADJUSTMENT OF SWR(standing wave ratio)

51 

 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 

5

0cm 

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 ▼ 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.

 

 

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.

Your RADIO is protected against 

a reversal

 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 

radio

 to a permanent (+) and (-). We 

advise you to connect the power cable directly to the battery (as 

the connection of the 

radio

 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.
