b) Install it so that it does not obstruct the driver and passengers of the vehicle.

v)It is necessary to anticipate the exit and safety of the cables (power, antenna, accessories ...) so that they do not interfere with the control of the vehicle.

G)For installation, use the fasteners ( 1) supplied with the radio, fix it firmly with the mounting bolts ( 2 ), which are also supplied in packaging (drilling diameter 3.2 mm). In doing so, do not damage the electrical system of the vehicle.

e)Choose a location for the microphone arm and arrange for the cord to pass through:

- NOTE:Having a plug socket on the front side, your CB radio can be built into the cockpit panel. In this case, it is recommended to connect a loudspeaker to it to better sound(EXT. SP connector located on the back of the radio: WITH). Consult your nearest distributor regarding the installation of your radio station.

2) ANTENNA INSTALLATION:

a) Antenna selection:

When using CIB, it is important to know that the larger the antenna, the greater the coverage range. Your salesperson will be able to help you with your choice.

b) Automotive antenna:

It should be installed on the part of the vehicle where there is a metal coating (mass), away from the windshield and rear window.

If a radiotelephone antenna is already installed on the vehicle, the CIB antenna must be one level higher.

- There are two types of antennas: regulated and adjustable

- Adjusted antennas are most often used in conjunction with good weight (upper body or trunk)

Adjustable antennas are less sensitive and can be used with less significant masses (see page 7 § 5 SWR ADJUSTMENT).

For an antenna that is installed in a drilled hole, it is very important to have excellent antenna / ground contact; to do this, erase a little of the body covering at the level of the bolt and fixing.

While pulling the cord, make sure that it is not too pinched or crushed (risk of breaking and short-circuiting).

Turn on the antenna (connector V).

v) Fixed antenna:

- It is recommended to install it in an unoccupied place. If the installation is to be carried out on a mast, you must attach the antenna in accordance with applicable law (ask distributor for information). The antennas and accessories that our company supplies are designed for optimal performance in each radio range.

3) POWER SUPPLY CONNECTION:

Your radio station PRESIDENT JOHNNY II ASC equipped with protection against polarity reversal. However, before switching on, make sure the connection is correct.

Current consumption at constant voltage Your radio station is 12 V. ( A). Today, most cars and trucks run on negative mass. This can be verified by making sure the (-) battery is connected to the motor unit or chassis. Otherwise, consult your dealer.

ATTENTION:Trucks usually have two batteries and a 24 V electrical unit. Therefore, a 24/12 V convector (PRESIDENT CV 24/12 model) must be added to the electrical circuit.

All of the following power-up operations must be performed without connecting the power cord to the radio:

a)Make sure the power is 12V.

b)Find the (+) and (-) battery (+ = red, - = black). If you need to extend the power cord, use a similar or thicker cord.

G)Connect red wire to (+) and black wire to (-) battery.

e)Connect the power cord to the radio.
