FM modulation to work always with a constant transmitting power
when measuring.
In any case, a value of 1:1.5 should be achieved. For mobile
operation,it does not make much sense to adjust a value of 1:1
by all means, since this value can always be modified again due
to different environments, cable modifications etc. However, we
recommend you to check the adjustment regularly, because an
unfavourable value points to connector and cable problems.
Power supply
A direct voltage of 13.2 volts is supplied to your radio set which
is equipped with a reverse voltage protection.
However, before switching it on, check the device for correct
polarity! A polarity reversal would result in a destruction of
your CB radio set.
The nominal supply voltage amounts to 13.2 V and must not exceed
15 V in any case. When transmitting, an electric current of approx.
1.3 A flows, up to 0.8 A at maximum volume and approx. 0.3 A
with activated squelch.
The negative pole is connected to ground (= chassis) as for almost
all modern cars.
Prior to connecting the radio set, check polarity and voltage: If the
vehicle is older, the positive pole can also be connected to ground.
Some commercial vehicles are supplied with a voltage of 24 V
instead of 12 V. When in doubt, contact your specialized car dealer!
After having checked the voltage and polarity, proceed as follows:
a) Your radio set is provided with a power supply cable (A) into
which a 2 A fuse is connected. Connect the cable directly to the
battery using the corresponding terminals:
Red
= positive pole,
black
= negative pole (ground).
b) Connect the cable directly to the storage battery of the vehicle.
When connecting the radio set to the cigarette lighter, for example,
the radio set is not supplied anymore with the necessary back-up
voltage after having switched off the ignition system of the vehicle.
c) Lay the power supply cable in the car such that the interferences
resulting from the ignition system are as small as possible.
ATTENTION:
If the fuse in the power supply cable is blown, proceed
as follows: a) Find and eliminate the cause, b) replace the blown
fuse by a new 2 A fuse!
Always switch the radio set off before leaving the vehicle in order
to avoid that the battery is run down.
