BASIC OPERATIONS TO BE CARRIED OUT BEFORE USING
YOUR SET FOR THE FIRST TIME (without transmitting or using
the <<Push-To-Talk>> switch on the microphone)
a) Connect the microphone
WARNING: This process 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 at the D bank in FM.
- Slide the switch on the SWR meter to position CAL or FWD.
-Press the <<Push-To-Talk>> switch on the microphone to
transmit.
- Adjust the index needle over ▼ sign by rotating the calibration knob .
-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.

HOW TO USE AN ESTERNAL SWR METER
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) Tune to channel 20 at the D bank by using either the UP or DN
key on the microphone or the rotary knob.

ADJUSTMENT OF SWR(standing wave ratio)
before switching it on, you are requested to check all the connections.
Your equipment must be supplied with a voltage of 12 volts DC(Direct
Current ). Today, most cars and trucks 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: trucks generally have two batteries to supply a voltage
of 24 volts, in which case it will be necessary to insert a 24/12 volt
inverter 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.
WARNING: Never replace the original fuse (10A) by one of a different
Your RADIO is protected against an inversion of polarities. However,
