WARNING !
Before using, be careful never to transmit without first
havingconnectedtheantenna(connection“B”situated
on the back panel of the equipment) or without having
set the SWR (Standing Wave Ratio) ! Failure to do so may
result in destruction of the power amplifier, which is not
covered by the warranty.
The warranty of this transceiver is valid only in the country of purchase.

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).
Adjustment with internal SWR-meter
Shortpress•F/MEMkey (6) and s(4) or UP (14)keytoswitch
on (/off) the SWR function (see § •SWR page 8). SWR

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.

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.
