WARNING !
Before using, be careful never to transmit without first having connected the
antenna (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 guarantee of this transceiver is valid only in the country of purchase.
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 ADAMS 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 ADAMS FCC.
INSTALLATION
- WHERE AND HOW TO MOUNT YOUR MOBILE CB RADIO
- You should choose the most appropriate setting from a simple and practical point of view.
- Your CB radio should not interfere with the driver or the passengers.
- 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.
-
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.
-
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.
-
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.
Note : 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: -
Ask your dealer for advice on mounting your CB radio.
ANTENNA INSTALLATION
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.
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 page 7, 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).
OUTPUT RADIUS PATTERN
Fixed antenna
- A fixed antenna should be installed in a 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 PRES-IDENT antennas and accessories are designed to give maximum efficiency to each CB radio within the range.
POWER CONNECTION
Your PRESIDENT ADAMS FCC 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.
- Check that the battery is of 12 volts.
- 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.
- 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).
Connect the red wire (+) to the positive terminal of the battery and the black (-) wire to the negative terminal of the battery. Connect the power cable to your CB radio.
WARNING : Never replace the original fuse by one of a different value.
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)
- Connect the microphone.
- Check the antenna connections.
- Turn the set on by turning the volume knob VOL (1) clockwise.
- Turn the squelch SQ knob (3) to minimum (M position).
- Adjust the volume to a comfortable level.
- Go to Channel 20 using either the s/t keys (2).
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)
-
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, type President CA- 2C). -
To adjust the SWR meter:
- Set the CB on 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 t 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. (An SWR reading between 1 and 1.8 is acceptable).
- It will be necessary to re-calibrate the SWR meter after each ad-justment of the antenna.
-
WARNING : In order to avoid any losses and attenuations in cables used
for connection between the radio and its accessories, PRES-IDENT recommends to
use a cable with a length inferior to 118.11 inches / 3 m.
