Welcome to the world of the new generation of CB
radios. The new PRESIDENT range gives you access to
top performance CB equipment. With the use of up-to­date technology, which guarantees unprecedented
quality, your PRESIDENT JACKSON II ASC is a new step in
personal communication and is the surest choice for the
most demanding of professional CB radio users. To en­sure that you make the most of all its capacities, we
advise you to read carefully this manual before installing
and using your PRESIDENT JACKSON II ASC.

A) INSTALLATION

1) WHERE AND HOW TO MOUNT YOUR MOBILE CB RADIO

a) You should choose the most appropriate setting from a simple and practical

point of view.

b) Your CB radio should not interfere with the driver or the passengers.

MOUNTING DIAGRAM

c) Remember to provide for the passing and protection of different wires (e.g.

power, antenna, accessory cabling) so that they do not in any way interfere
with the driving of the vehicle.

d) To install your equipment, use the cradle (1) and the self-tapping screws [2]

provided (drilling diameter 3.2 mm). Take care not to damage the vehicle’s
electrical system while drilling the dash board.

e) Do not forget to insert the rubber joints [3] between the CB and its support as

these have a shock-absorbing effect which permits gentle orientation and
tightening of the set.

f) Choose where to place the microphone support and remember that the

microphone cord must stretch to the driver without interfering with the controls
of the vehicle.

- N.B. : As the transceiver has a frontal microphone socket, it can be set into the

dash board. In this case, you will need to add an external loud speaker to
improve the sound quality of communications (connector EXT.SP situated on
the back panel: C). Ask your dealer for advice on mounting your CB radio.

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 (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 accesso-

English

ries are designed to give maximum efficiency to each CB radio within the
range.

3) POWER CONNECTION

Your PRESIDENT JACKSON II ASC 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 (6 A) by one of a different 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 volume knob (1) clockwise.
d) Turn the squelch knob (2) to minimum (M position).
e) Adjust the volume to a comfortable level.
f) Go to Channel 20 using either the «UP» «DN» key on the microphone or the

rotary knob.

5) 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 a built-in SWR meter or external SWR meter (e.g. TOS-1 or

TOS-2 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 in FM.

- Put the switch on the SWR meter to position CAL or FWD.

- Press the «push-to-talk» switch on the microphone to transmit.

- Bring the index needle to  by using the calibration key.

- Change the switch to position SWR (reading of the SWR level). The reading on
the Meter should be as near as possible to 1. If this is not the case, re-adjust your
antenna to obtain a reading as close as possible to 1. (An SWR reading
between 1 and 1.8 is acceptable).

- It will be necessary to re-calibrate the SWR meter after each adjustment of the
antenna.

WARNING: In order to avoid any losses and attenuations in cables used for
connection between the radio and its accessories, PRESIDENT recommends
to use a cable with a length inferior to 3m.

Your CB is now ready for use.

B) HOW TO USE YOUR CB

1) ON/OFF - VOLUME ~ RF POWER
ON/OFF - VOLUME

a) To turn the set on, turn the knob (1) clockwise.
b) To increase the sound level, turn the same knob further clockwise.

RF POWER

Adjustment of the output power in AM and FM mode only. Allows reducing the
power in case of a nearby communication with a person who has no RF GAIN.

The normal position of this function is set to maximum, fully clockwise.

2) ASC (Automatic Squelch Control) SQUELCH ~ CAL

SQUELCH

Suppresses undesirable background noises when there is no communication.
Squelch does not affect neither sound nor transmission power, but allows a
considerable improvement in listening comfort.

a) ASC: Automatic Squelch Control

Worldwide patent, a PRESIDENT exclusivity.
Turn the squelch knob (2) anti-clockwise into ASC position. The «ASC/VOX» led
lights up into green.

Note: If the VOX function is also active, the led lights up into orange.
No repetitive manual adjustment and a permanent improvement in listening

comfort when ASC is active. This function can be disconnected by turning the
switch clockwise. In this case the manual squelch control becomes active
again. The «ASC/VOX» led turns off.

b) MANUAL SQUELCH

Turn the squelch knob clockwise to the exact point where all background
noise disappears. This adjustment should be done with precision as, if set to
maximum (fully clockwise) only the strongest signals will be received.

CAL

Allows the calibration of the SWR meter (see § 5 ADJUSTMENT OF SWR).
