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-to-date technology, which guarantees unprecedented quality, your
PRESIDENT JOHNNY III USA 12/24 V 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
JOHNNY III USA 12/24 V.

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.
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.

MOUNTING

DIAGRAM

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 § 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.

OUTPUT RADIUS PATTERN

3) POWER CONNECTION

Your PRESIDENT JOHNNY III USA 12/24 V 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 or 24 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 or 24 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 (2 A) by one of a different value.

6

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 SQ knob (2) to minimum (M position).
e) Adjust the volume to a comfortable level.
f) Go to channel 20 by using the rotary knob or UP/DN key on the microphone (5).

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 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 15” 3/4 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 FWD (calibration).

- 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 REF (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. (A 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 9’ 10”.

Your CB is now ready for use.

B) HOW TO USE YOUR CB

1) ON/OFF – VOLUME

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

2) ASC (Automatic Squelch Control) / 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 SQ knob (2) anti-clockwise into ASC position. “ASC” appears on the display. No

repetitive manual adjustment and a permanent improvement between the sensitivity
and the listening comfort when ASC is active. This function can be disconnected by
turning the switch clockwise. In this case the squelch adjustment becomes manual
again. “ASC” disappears from the display.

b) MANUAL SQUELCH

Turn the SQ 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.

A) INSTALLATION

1) CHOIX DE L’EMPLACEMENT ET MONTAGE DU POSTE MOBILE

a) Choisissez l’emplacement le plus approprié à une utilisation simple et pratique de

votre poste mobile.

b) Veillez à ce qu’il ne gêne pas le conducteur ni les passagers du véhicule.
c) Prévoyez le passage et la protection des différents câbles, (alimentation, antenne, ac-

cessoires...) afin qu’ils ne
viennent en aucun cas
perturber la conduite du
véhicule.

SCHÉMA GÉNÉRAL

DE MONTAGE

d) Utilisez pour le montage le berceau (1) livré avec l’appareil, fixez-le solidement à

l’aide des vis auto taraudeuse (2) fournies (diamètre de perçage 3,2 mm). Prenez
garde de ne pas endommager le système électrique du véhicule lors du perçage
du tableau de bord.

e) Lors du montage, n’oubliez pas d’insérer les rondelles de caoutchouc (3) entre le

poste et son support. Celles-ci jouent en effet un rôle «d’amortisseur» et permettent
une orientation et un serrage en douceur du poste.

f) Choisissez un emplacement pour le support du micro et prévoyez le passage de son

cordon.

- NOTA : Votre poste mobile possédant une prise micro en façade peut être encastré

dans le tableau de bord. Dans ce cas, il est recommandé d’y adjoindre un haut­parleur externe pour une meilleure écoute des communications (connecteur EXT.SP.
situé sur la face arrière de l’appareil : C). Renseignez-vous auprès de votre revendeur
le plus proche pour le montage sur votre appareil.

2) INSTALLATION DE L’ANTENNE

a) Choix de l’antenne

- En CB, plus une antenne est grande, meilleur est son rendement. Votre Point Conseil

saura orienter votre choix.

b) Antenne mobile

- Il faut l’installer à un endroit du véhicule où il y a un maximum de surface métallique

(plan de masse), en s’éloignant des montants du pare-brise et de la lunette arrière.

- Dans le cas où une antenne radiotéléphone est déjà installée, l’antenne CB doit

être au-dessus de celle-ci.

- Il existe 2 types d’antennes : les préréglées et les réglables.

- Les préréglées s’utilisent de préférence avec un bon plan de masse (pavillon de toit

ou malle arrière).

- Les réglables offrent une plage d’utilisation beaucoup plus large et permettent de

tirer parti de plans de masse moins importants (voir § 5 RÉGLAGE DU TOS) .

- Pour une antenne à fixation par perçage, il est nécessaire d’avoir un excellent

contact antenne/plan de masse ; pour cela, grattez légèrement la tôle au niveau
de la vis et de l’étoile de serrage.

- Lors du passage du câble coaxial, prenez garde de ne pas le pincer ou l’écraser

(risque de rupture ou de court-circuit).

- Branchez l’antenne (B).

c) Antenne fixe

- Veillez à ce qu’elle soit dégagée au maxi-

mum. En cas de fixation sur un mât, il faudra
éventuellement haubaner conformément
aux normes en vigueur (se renseigner au­près d’un professionnel). Les antennes et
accessoires PRESIDENT sont spécialement
conçus pour un rendement optimal de
chaque appareil de la gamme.

3) CONNEXION DE L’ALIMENTATION

Votre PRESIDENT JOHNNY III USA 12/24 V est muni d’une protection contre les inversions

de polarité. Néanmoins, avant tout branchement, vérifiez vos connexions.

Votre poste doit être alimenté par une source de courant continu de 12 ou 24 Volts

(A). À l’heure actuelle, la plupart des voitures et des camions fonctionnent avec
une mise à la masse négative. On peut s’en assurer en vérifiant que la borne (-) de
la batterie soit bien connectée au bloc moteur ou au châssis. Dans le cas contraire,
consultez votre revendeur.

a) Assurez-vous que l’alimentation soit bien de 12 ou 24 Volts.
b) Repérez les bornes (+) et (-) de la batterie (+ = rouge, - = noir). Dans le cas où il

serait nécessaire de rallonger le cordon d’alimentation, utilisez un câble de section
équivalente ou supérieure.

c) Il est nécessaire de se connecter sur un (+) et un (-) permanents. Nous vous conseillons

donc de brancher directement le cordon d’alimentation sur la batterie (le bran­chement sur le cordon de l’autoradio ou sur d’autres parties du circuit électrique
pouvant dans certains cas favoriser la réception de signaux parasites).

d) Branchez le fil rouge (+) à la borne positive de la batterie et le fil noir (-) à la borne

négative de la batterie.

e) Branchez le cordon d’alimentation au poste.
ATTENTION : Ne jamais remplacer le fusible d’origine (2 A) par un modèle d’une valeur

différente !
