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 volume knob (1) clockwise.

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

e) Adjust the volume to a comfortable level.

f) Go to channel 20 by using the rotary knob (5).

5) ADJUSTMENT OF SWR (Standing wave ratio)

WARNING: This must be carried out when you use your CB radio for the ﬁ rst 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)

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 (calibration).

- Press the «push-to-talk» switch on the microphone to transmit.

- Bring the index needle to W by using the calibration key.

- Change the switch to position SWR (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 adjustment of the

antenna.

WARNING: In order to avoid any losses and attenuations in cables used for connec-

tion between the radio and its accessories, PRESIDENT recommends to use a cable

with a length inferior to 3m.

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 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.

a) ASC: AUTOMATIC SQUELCH CONTROL

Worldwide patent, a PRESIDENT exclusivity.

Turn the SQ knob (2) anti-clockwise into ASC position. «ASC» appears on the display. No

repetitive manual adjustment and a permanent improvement between the sensitivity

and the listening comfort when ASC is active. This function can be disconnected by

turning the switch clockwise. In this case the squelch adjustment becomes manual

again. «ASC» disappears from the display.

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.
