Frequently Asked Questions - JOHNNY II PRESIDENT

How to adjust SWR (Standing Wave Ratio) on the PRESIDENT JOHNNY II ?

To adjust SWR, connect an external SWR meter (such as PRESIDENT TOS-1 or TOS-2) between the radio and the antenna. Select channel 20, then in transmit mode, calibrate the SWR meter and read the SWR value. Adjust the antenna to obtain a value as close to 1 as possible (acceptable up to 1.8). This operation is mandatory upon first use or after changing the antenna.

How to use the ASC (Automatic Squelch Control) function ?

ASC is an automatic squelch adjustment, exclusive to PRESIDENT. To activate it, turn the SQUELCH knob fully counterclockwise. This continuously optimizes sensitivity and listening comfort. To deactivate ASC and switch to manual squelch, turn the knob clockwise until the background noise disappears.

Which antenna to use with the PRESIDENT JOHNNY II ?

It is recommended to use a CB antenna with an impedance of 50 ohms. For a mobile installation, choose an antenna suitable for your vehicle (pre-tuned or adjustable). For a fixed station, prefer a clear antenna, possibly on a guyed mast. The choice of antenna affects efficiency and SWR.

What to do if the device does not turn on ?

First check the supply voltage (12 V DC) and polarity: red wire to (+), black wire to (-). Check the fuse (2 A). Make sure the power cord is correctly connected to the radio and the battery. If the problem persists, consult your dealer.

How to adjust the RF GAIN ?

The RF GAIN knob adjusts receive sensitivity. For long-distance communications, set it to maximum (clockwise). For short-range communications, decrease the gain to avoid distortion. The normal position is at maximum.

How to select a frequency band ?

Turn off the device, set the F/OFF switch to F, turn on again, rotate the channel selector to choose the desired band (see table on page 48 of the manual). Set F/OFF back to OFF, turn off then on to confirm.

What does the TX indicator mean ?

The TX indicator lights up when the device switches to transmit (when you press the microphone PTT). It confirms that the radio is transmitting. If it flashes, check that the antenna is connected and that SWR is correct.

How to clean and maintain the PRESIDENT JOHNNY II ?

Clean the device with a soft, dry cloth. Do not use solvents or abrasive products. Avoid moisture and extreme temperatures. Regularly check connections and the fuse condition.

What is the maximum receive power ?

The maximum audio power in receive is 5 W. Use an external speaker (8 Ω, 3.5 mm jack) if necessary for better listening.

How to use channel 19 ?

To directly access channel 19 (road channel), set the CH19 switch to ON. The radio automatically tunes to channel 19. To return to the previous channel, set the switch back to OFF.

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.

The guarantee of this transceiver is valid only in the country pf 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 JOHNNY II ASC 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 JOHNNY II ASC.

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) 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) 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 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 p 27 § 5, 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).

c) 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 PRESIDENT antennas and accessories are designed to give maximum efficiency to each CB radio within the range.

3) POWER CONNECTION:

Your PRESIDENT JOHNNY II ASC 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.

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 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 (2 A) by one of a different value.

4) 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):

a) Connect the microphone
b) Check the antenna connections
c) Turn the set on by turning the knob VOLUME clockwise.
d) Turn the SQUELCH knob to minimum (anti-clockwise). Adjust the volume to a comfortable level.
e) Go to Channel 20 using the rotary knob on the front panel.

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.

* Using an external SWR meter (e.g. SWR 1 or SWR 2):

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 to channel 20.
• Put the switch on the SWR meter to position CAL ou FWD.
• Press the «push-to-talk» switch on the microphone to transmit.
• Bring the index needle to ▼ by using the calibration key.
• Change the switch to position SWR (reading of the SWR level). The reading on the V.U. 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 adjustment of the antenna.

Your CB is now ready for use.

a) To turn the set on, turn the knob (1) clockwise
b) To increase the sound level, turn the same knob further clockwise.

2) ASC (Automatic Squelch Control)/SQUELCH :

Suppresses undesirable back-ground noises when there are no communication. Squelch does not effect neither sound nor transmission power, but allows a considerable improvement in listening comfort.

a) ASC: Automatic Squelch Control

Worldwide patent, a PRESIDENT exclusivity

No repetitive manual adjustment and a permanent improvement in listening comfort when this function is active. It can be disconnected by turning the switch (2) clockwise, in this case the manual squelch control becomes active again.

b) Manual squelch

Turn the squelch knob clockwise to the exact point where all background noise disappears. This adjustment should be done with precision as, if set to maximum, (i.e. fully clockwise) only the strongest signals will be received.

3) RF GAIN:

This knob is for adjusting sensitivity during reception. For long distance communications RF GAIN should be set to maximum. RF GAIN can be reduced to avoid distortion, when your correspondent is close by and who does not have the RF POWER function. The normal setting of this knob is on maximum (fully clockwise).

4) CHANNEL SELECTOR ROTARY KNOB:

Turning this knob allows you to choose a channel (1-40) for transmitting and receiving.

5) DISPLAY:

The display shows all the different functions. The bargraph shows the level of reception and the level of power emitted. The TX LED lights up when the set goes into transmission mode.
