Welcome to the world of the new generation of CB radios. The new PRESIDENT
range gives you access to top performance transceiver equipment. With the
use of up-to-date technology, which guarantees unprecedented quality, your
PRESIDENT WALKER III FCC 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 WALKER III FCC.
A) INSTALLATION
1) WHERE AND HOW TO MOUNT YOUR MOBILE CB RADIO
a) You should choose a well ventilated place 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.
d) To install your equipment, use the cradle (1) and the self-tapping screws
(2) provided (drilling diameter 1.126 in / 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 transceiver
antenna should be higher than this.
English

6
- 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).
- Foranantenna which must be fixed by drilling, you will need agoodcontact
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 WALKER III FCC 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.
WARNING: Trucks 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 connec-
tion 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 transceiver to a permanent (+) and (-).
We advise you to connect the power cable directly to the battery (as the
connection of the transceiver 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 differ-
ent value.
4) BASICOPERATIONSTO BECARRIED OUTBEFORE USINGYOUR
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.
e) Adjust the volume to a comfortable level.
f) Go to channel 20 by using rotary PUSH knob (6) or UP/DN buttons (18) on
the microphone.
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 internal SWR-meter
NEW, EASY AND VERY HANDY- Adjustment of SWR meter by beep tones
See menu SWR ADJUSTMENT function page 12.
English

7
* 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 15.75 in / 40 cm cable, type President
CA 2C).
b) To adjust the SWR meter:
- Set the CB on channel 20.
- Put the switch on the SWR-meter to position FWD (calibration).
- Press the PTT “push-to-talk” switch (17) 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, readjust
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 recalibrate the SWR meter after each adjustment of
the antenna.
WARNING: In order to avoid any losses and attenuations in cables used for
connectionbetweentheradioanditsaccessories,PRESIDENTrecommends
to use a cable with a length inferior to 118.11 in / 3 m).
Your transceiver is now ready for use.

2) INSTALACIÓN DE LA ANTENA
a) Elección de la antena
- En CB, cuanto más grande es una antena, mejor es su rendimiento. Su
Centro de Asesoramiento sabrá orientarle en su elección.
b) Antena móvil
- Hay que instalarla en un lugar del vehículo donde haya un máximo de
superficie metálica (plano de masa), alejándose de los montantes del
parabrisas y de la luneta trasera.
- En caso de que se haya instalado una antena de radio-teléfono, la antena
CB debe estar por encima de ésta.
- Existen 2 tipos de antenas: las preajustadas y las regulables.
Español

19
- Las preajustadas se utilizan preferentemente con un buen plano de masa
(en el techo o en el maletero).
- Las regulables ofrecen un campo de uso mucho más extenso y permiten
sacar partido de planos de masa menos importantes (véase § AJUSTE DE
LA ROE página 19).
- Para una antena de fijación por taladro, es necesario tener un contacto
excelenteentrelaantenay el plano demasa;paraello,rasqueligeramente
la chapa al nivel del tornillo y de la estrella de presión.
- En el momento del paso del cable coaxial, tenga cuidado de no pelliz-
carlo ni aplastarlo (riesgo de rotura o cortocircuito).
- Conecte la antena (B).
Lassiguientesoperacionesdeconexióndebenser efectuadas con el cable
de alimentación no conectado a la estación:
a) Asegúrese de que la alimentación sea de 12 voltios.
b) Localice los bornes (+) y (-) de la batería (+= rojo, -= negro). En caso de
que sea necesario alargar el cable de alimentación, utilice un cable de
sección equivalente o superior.
c) Es necesario conectarse a un (+) y un (-) permanentes. Le aconsejamos
pues, que conecte directamente el cable de alimentación a la batería
(el acoplamiento al cable de la auto-radio o a otras partes del circuito
eléctrico pueden, en ciertos casos, favorecer la recepción de señales
parásitas).
d) Conecteelhilorojo (+)alborne
positivo de la batería y el hilo
negro (-) al borne negativo de
la batería.
e) Conecte el cable de alimen-
tación a la estación.
ATENCIÓN: ¡Nunca reempla-
ce el fusible de origen por un

c) Antena fija
- Procure abrirla al máximo. En caso de fijación sobre un poste, habrá que
sostenerla eventualmente conforme a las normas vigentes (infórmese con
un profesional). Las antenas y los accesorios PRESIDENT han sido especial-
mente concebidos para un rendimiento óptimo de todos los aparatos de
la gama.
3) CONEXIÓN DEL ALIMENTADOR
Su PRESIDENT WALKER III FCC ASC está provista de una protección contra
las inversiones de polaridad.
Vuestra emisora debe ser alimentada por una fuente de corriente conti-
nua de 12 voltios (A). Actualmente, la mayoría de los coches y camiones
funcionan con una conexión de masa negativa. Podemos asegurarnos
verificando que el borne (-) de la batería esté bien conectado al bloque
motor o al chasis. En el caso contrario, consulte a su vendedor.
ATENCIÓN: Los camiones poseen generalmente dos baterías y una insta-
lación eléctrica de 24 voltios. Será necesario pues intercalar en el circuito
eléctrico un convertidor de 24/12 voltios (Tipo PRESIDENT CV 24/12).
