PRESIDENT HARRY Manuel D'utilisation page 26

a) Choosing your antenna:
- For CB radios, the longer the antenna, the better its results. Your
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 27 § 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 (B).
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 antennas and accessories are designed to
give maximum efficiency to each CB radio within the range.
3) POWER CONNECTION:
OUTPUT RADIUS PATTERNS
Your PRESIDENT HARRY ASC is protected against an inversion of polarities. However, before
dealer will 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.
