Welcome to the world of the new generation of CB ra-
dios. The new PRESIDENT range gives you access to top
performance CB equipment. With theuseofup-to-date
technology,which guarantees unprecedentedquality,
your PRESIDENT JOHNSON II 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
adviseyou to readcarefully this manual before installing
and using your PRESIDENT JOHNSON II 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.
d) Toinstallyour equipment,usethe cradle(1) andtheself-tap-
ping 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
thebackpanel:C).Askyourdealerforadviceonmounting
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 §
ADJUSTMENT OF SWR page 7).
- Foran antenna whichmustbefixed by drilling,youwillneed
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 acces-
sories are designed to give maximum efficiency to each
CB radio within the range.
3) POWER CONNECTION
Your PRESIDENTJOHNSONII USA12/24Visprotected against
aninversionofpolarities.However,beforeswitching iton,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
thebattery(as the connection of the CBcabletothewiring
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.
4) BASICOPERATIONSTOBE CARRIEDOUTBEFOREUSING
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 (Mposition).
e) Adjust the volume to a comfortable level.
f) Go to channel 20 by using s, t, UP or DN keys (4, 5, 15,
14).
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.
Adjustmentwith external SWR-meter(e.g.TOS-1PRESIDENT)
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 inches (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 FWD (calibra-
tion).
- Press the “push-to-talk” switch on the microphone to trans-
mit.
- Bring the index needle to tby using the calibration key.
- Changetheswitchto positionREF(readingoftheSWRlevel).
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 118.11 inches (3 m).

Bienvenido al mundo de los emisores-receptores CB de
última generación. Esta nueva gama de estaciones le
permite acceder a la comunicación electrónica más
competitiva. Gracias a la utilización de tecnología
punta que garantiza una calidad sin precedentes, su
PRESIDENTJOHNSON II USA12/24 V representaun nuevo
hito en la facilidad de uso y la solución por excelencia
para el pro más exigente de CB. Para sacar el máximo
partido de todas sus posibilidades, le aconsejamos leer
atentamenteestasinstruccionesdeusoantesde instalar
y utilizar su CB PRESIDENT JOHNSON II USA 12/24 V.
A) INSTALACIÓN
1) ELEGIR EL EMPLAZAMIENTO Y MONTAJE DEL PUESTO
MÓVIL
a) Escoja el emplazamiento más apropiado para una utiliza-
ción simple y práctica de su estación móvil.
b) Procure que no moleste ni al conductor ni a los pasajeros
del vehículo.
c) Prevea el paso y la protección de los diferentes cables,
(alimentación, antena, accesorios) con el fin de que en
ningún caso perturben la conducción del vehículo.
d) Utilice para el montaje el soporte (1) entregado con el
aparato, fíjelo sólidamente con ayuda de los tornillos au-
to-roscantes (2) proporcionados (diámetro de agujero de
3,2 mm). Tenga cuidado de no dañar el sistema eléctrico
del vehículo en el momento del taladro del salpicadero.
e) En el momento del montaje, no se olvide de insertar las
arandelas de caucho (3) entre la estación y su soporte.
Éstas tienen, en efecto, un papel “amortiguador” y per-
miten una orientación y presión suaves de la estación.
f) Escoja un emplazamiento para el soporte del micro y
prevea el paso de su cable.
- NOTA: Su estación móvil que posee una toma de micro en
la parte anterior puede ser empotrada en el cuadro de
mandos. En ese caso, se recomienda añadirle un altavoz
externo para una mejor escucha de las comunicaciones
(conector EXT.SP situado en la cara posterior del aparato:
C). Infórmese con su vendedor más próximo para el mon-
taje en su aparato.

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), ale-
jándose de los montantes del parabrisas y de la luneta
trasera.
- En caso de que se haya instalado una antena de radio-te-
léfono, la antena CB debe estar por encima de ésta.
- Existen2tiposdeantenas:laspreajustadasy las regulables.
- 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 an-
cho y permiten sacar partido de planos de masa menos
importantes (véase § 5 AJUSTE DE LA ROE).
- Para una antena de fijación por taladro, es necesario
tener un contacto excelente entre la antena y el plano
de masa; para ello, rasque ligeramente la chapa al nivel
del tornillo y de la estrella de presión.
- En el momento del paso del cable coaxial, tenga cuidado
de no pellizcarlo ni aplastarlo (riesgo de rotura o cortocir-
cuito).
- Conecte la
antena (B).
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 especialmen-
te concebidos para un rendimiento óptimo de todos los
aparatos de la gama.
3) CONEXIÓN DEL ALIMENTADOR
Su PRESIDENT JOHNSON II USA 12/24 V está provista de una
protección contra las inversiones de polaridad.
Vuestra emisora debe estar alimentada por una fuente de
corriente continua de 12 o 24 voltios (A). En este momento,
la mayor parte de los coches y camiones funcionan con
unatomadetierranegativa,sepuedeasegurarverificando
que el terminal (-) de la batería esté bien conectado al
bloque del motor o bastidor. En el caso contrario, consulte
con su suministrador.
Todas las operaciones de conexión siguientes, deben
efectuarse con el cable de alimentación no conectado
a la emisora:
a) Asegúrense que el alimentador sea de 12 o 24 Voltios.
b) Identifique los polos (+) y (-) de la batería (+= rojo, -=
negro). En el caso que sea necesario alargar el cable de
alimentación utilice un cable de sección equivalente o
superior.

c) Es necesario conectar sobre un (+) y (-) permanentes.
Les aconsejamos enchufar directamente el cable de
alimentación en la batería (el enchufe sobre el cable del
auto-radio o sobre otras partes del circuito electrónico
podrán en ciertos casos favorecer la recepción de las
señales parásitas).
d) Conecten el hilo rojo (+) al borne positivo de la batería y
el hilo negro (-) al borne negativo de la batería.
e) Conectar el cable de alimentación a la emisora.
ATENCIÓN: ¡No reemplace jamás el fusible de origen (2 A)
por un modelo de un valor diferente!
4) OPERACIONESDEBASEQUE HAYQUEEFECTUARANTES
DE LA PRIMERA UTILIZACIÓN, SIN PASAR POR EMISIÓN
(sin apretar la palanca del micro)

5) AJUSTE DE LA ROE (Relación de Ondas Estacionarias)
ATENCIÓN:Esta operacióndebeefectuarsenecesariamen-
te en el momento de la primera utilización del aparato o
en el momento de un cambio de antena. Este ajuste debe
se realizar en un lugar abierto, al aire libre.
Ajustes con el medidor de ROE externo (tipo TOS-1
PRESIDENT):
a) Empalme del medidor de ROE:
- Conecte el medidor de ROE entre la estación y la antena,
lo más cerca posible de la estación (utilice para ello un
cable de 40 cm máximo tipo CA-2C PRESIDENT).
b) Ajuste de la ROE:
- Posicione la estación hacia el canal 20,
- Sitúe el conmutador del medidor de ROE en posición FWD
(calibración),
- Apriete la palanca del micro para pasar a emisión,
- Dirija la aguja al índice ▼con ayuda del botón de cali-
bración,
- Ponga el conmutador en posición REF (lectura del valor de la
ROE). El valor leído en el indicador debe estar muy cerca de 1.
En caso contrario, reajuste su antena hasta obtener un valor lo
más cerca posible a 1 (puede aceptarse un valor de la ROE
comprendido entre 1 y 1,8),
- Es necesario recalibrar el medidor de ROE entre cada
operación de ajuste de la antena.
Observación: Con el fin de evitar las pérdidas y las ate-
nuaciones en los cables de conexión entre la radio y sus
accesorios, PRESIDENT recomienda una longitud de cable
inferior a 3m.
