Your RADIO is protected against an inversion of polarities. However,
before switching it on, you are
Your equipment must be supplied with a
Current). Today, most cars and
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
3
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
value.

d) Turn the squelch knob to minimum
e) Adjust the volume to a comfortable level

5. ADJUSTMENT OF SWR(standing wave ratio)
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
-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
-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.
