PRESIDENT JFK III (01) PDF DOCUMENT

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 guarantee.

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 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.: Your mobile radio with front-mounted microphone socket can be flush-mounted in the dashboard using the flush-mounting rack supplied. Contact your nearest dealer for details of how to mount your radio.

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.

– 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.

– 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 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.

Your PRESIDENT JFK III 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).

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 by one of a different value.

These operations are to be performed 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 VOL knob (1) clockwise.

d) Turn the squelch SQ knob (2) to minimum M.

e) Adjust the volume to a comfortable level.

f) Go to channel 20 by using the CH rotary knob (6) or UP/DN keys (13) on the microphone.

This adjustment must be carried out when you use your radio for the first time and whenever you re-position your antenna. This must be carried out in an obstacle-free area.

There are two methods: using the internal SWR-meter or an external SWR-meter.

Adjustment with internal SWR-meter

See function SWR CALIBRATION for instructions.

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 40 cm cable, type President CA 2C).

b) To adjust the SWR meter:

– Set the CB on channel 20 in FM.

– Put the switch on the SWR-meter to position FWD (calibration).

– Press the PTT “push-to-talk” switch (12) 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 connection between the radio and its accessories, PRESIDENT recommends to use a cable with a length inferior to 3 m.

Turn on: turn VOL knob (1) clockwise. If the function KEY BEEP is active, the radio emits a beep. The radio is “on”. The display briefly shows the frequency band and the microphone type.

Turn Off: turn VOL knob (1) counterclockwise until the radio emits a click sound. Your radio is “off”.

Volume Adjustment: rotate VOL knob (1) clockwise to increase the volume. Turn the same knob counterclockwise to reduce the sound level.

Squelch suppresses undesirable background noises when there is no communication. It does not affect sound or transmission power, but allows a considerable improvement in listening comfort.

a) ASC: AUTOMATIC SQUELCH CONTROL

Turn the SQ knob (2) anti-clockwise into the ASC position. The ASC icon appears on the LCD. This feature provides a permanent improvement between sensitivity and listening comfort without repetitive manual adjustment. This function can be disconnected by turning the switch clockwise, and the ASC icon will disappear from the LCD.

b) MANUAL SQUELCH

Turn the SQ knob (2) 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.

AM/FM (short press)

This switch allows selecting the modulation mode AM or FM. Your modulation mode has to correspond to the one of your correspondent.

– Amplitude Modulation / AM: communication on a field with relief and obstacles at middle distance (the most used).

– Frequency Modulation / FM: for nearby communications on a flat open field.

– In U configuration only: in FM mode, a short press on the AM/FM key (4) alternates between the ENG or CEPT frequency bands. “UK” is displayed when the ENG frequency band is selected.

PA (Public Address)

An external loudspeaker can be connected to the unit by the PA jack plug located on the back panel PA.SP. (D). Turn the VOL knob (1) to adjust the PA volume. See the PA SETTING menu for more details.

– ANL – Automatic Noise Limiter: This filter allows the reduction of background noises and some reception interferences. In AM mode only.

– NB – Noise Blanker: This filter allows the reduction of back ground noise, and some reception interference.

HI-CUT (long press)

Long press the ANL/NB key (6) to activate/deactivate the HI-CUT filter. “HIC” appears on the display when the filter is active. Hi-Cut eliminates high frequency interferences and should be used in accordance with the reception conditions.

NRC

This switchable filter improves the reception and transmission mode. Press the F key (7), then press the ANL/NB key (6) to activate/deactivate the NRC. When the NRC is active, “nrc” appears on the display. The filter can be set independently in the NRC SET menu.
