Operation Manual

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
§ 4, 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 to the adapter.
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 de-
signed to give maximum efficiency
to each CB radio within the range.
3) BASIC OPERATIONS TO BE CARRIED OUT BEFORE USING
YOUR SET FOR THE FIRST TIME (without transmitting and
without using the «push-to-talk» switch)
a) Check the antenna connections.
b) Turn the set on by turning the Power knob (12) clockwise.
c) Turn the squelch SQ knob (4) OFF.
d) Adjust the volume to a comfortable level.
e) Go to channel 20 by using the channel selectors (5 & 8).
4) ADJUSTMENT OF SWR (Standing wave ratio)
WARNING: This must be carried out when you use your CB 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 external SWR-meter (e.g. TOS-1 PRESIDENT)
a) To connect the SWR meter:
- Connect the SWR meter between the CB radio and the antenna as close as
possible to the CB (use a maximum of 40 cm cable, type President CA 2C).
b) To adjust the SWR meter:
- Set the CB to channel 20.
- Put the switch on the SWR-meter to position CAL (calibration).
