OUTPUT RADIUS PATTERN
2) ANTENNA INSTALLATION:
a) Choosing your antenna:
-
For CB radios, the longer the antenna, the better its results. Your dealer will be
able to help you with your choice of antenna.
b) Mobile antenna:
-
Must be fixed to the vehicle where there is a maximum of metallic surface (ground
plane), away from windscreen mountings.
-
If you already have a radio-telephone antenna installed, the CB antenna should be
higher than this.
-
There are two types of antenna: pre-regulated
which should be used on a good
ground plane (e.g. car roof or lid of the boot),
and
.
adjustable
which offer a much larger range and can be used on a smaller ground
plane (see p 31 § 5, Adjustment of SWR).
-
For an antenna which must be fixed by drilling, you will need a good contact
between the antenna and the ground plane. To obtain this, you should lightly scratch
the surface where the screw and tightening star are to be placed.
-
Be careful not to pinch or flatten the coaxial cable (as this runs the risk of break down
and/or short circuiting).
-
Connect the antenna (

).
c) Fixed antenna:
-
A fixed antenna should be installed in a clear a space as possible. If it is fixed to a mast,
it will perhaps be necessary to stay it, according to the laws in force (you should seek
professional advice). All PRESIDENT an-
tennas and accessories are designed to
give maximum efficiency to each CB ra-
dio within the range.
3) POWER CONNECTION:
Your PRESIDENT HARRY II Classic 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 (
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 and an electrical installation of 24
volts, in which case it will be necessary to insert a 24/12 volt converter (type CV 24/
12 PRESIDENT) into the electrical circuit. The following connection steps should be
carried out with the power cable disconnected from the set.
a)
Check that 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, you should use the same or a
superior type of cable.
c)
It is necessary to connect your CB to a permanent (
+
) and (
-
). We advise you to
connect the power cable directly to the battery (as the connection of the CB cable
to the wiring of the car-radio or other parts of the electrical circuit may, in somecases,
increase the likelihood 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
CB radio.
WARNING:
Never replace the
original fuse (2 A) by one of a
different value.
