English

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.

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 back-ground noises when there are no communication.

Squelch does not effect neither sound nor transmission power, but allows a consid-

erable 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 back-

ground 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 communica-

tions 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).
