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.
e) Adjust the volume to a comfortable level.
f) Go to channel 20 by using the channel selector (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 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) 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.
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.
3) DISPLAY
