How To Use Your Cb - PRESIDENT HENRY ASC Classic 12/24 V Manual Del Usuario

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 VOL (1) clockwise.
d) Turn the squelch SQ knob (2) to minimum (M position).
e) Adjust the volume VOL (1) to a comfortable level.
f) Go to channel 20 by using the channel selector (4).
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.
* 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 FWD (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 REF (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 connection
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 VOL (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. No repetitive manual ad-
justment 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.
b) MANUAL SQUELCH
Turn the SQ knob (2) clockwise to the exact point where all background noise dis-
appears. This adjustment should be done with precision as, if set to maximum (fully
clockwise), only the strongest signals will be received.
