PRESIDENT JIMMY III Manuel D'utilisation page 24

- 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
§ HOW TO ADJUST SWR, below).
- 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).
OUTPUT RADIUS PATTERN
c) Fixed antenna
- A fixed antenna should be installed in as clear 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
Your PRESIDENT JIMMY III is protected against an inversion of polarities.
However, before switching it on, you are advised to check all the connec-
tions. 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.
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 some cases, 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 by one of a dif-
ferent value.
4) BASIC OPERATIONS TO BE CARRIED OUT BEFORE USING YOUR
SET FOR THE FIRST TIME (without transmitting and without
using the "push-to-talk" switch on the microphone)
a) Connect the microphone.
b) Check the antenna connections.
c) Turn the set on by turning the VOL knob (1) clockwise.
d) Turn the squelch SQ knob (2) to minimum M.
e) Adjust the volume to a comfortable level.
f) Go to channel 20 by using the / keys (4) on the transceiver.
5) HOW TO ADJUST SWR (Standing Wave Ratio)
Warning: This must be carried out when you use your radio for the first time
and whenever you re-position your antenna. This adjustment must be car-
ried 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 on channel 20 in AM.
Put the switch on the SWR-meter to position FWD (calibration).
-
- Press the PTT "push-to-talk" switch (7) on the microphone to transmit.
- Bring the index needle to  by using the calibration key.
