How To Use Your Cb - PRESIDENT ADAMS FCC Owner's Manual

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 (3) to minimum (M position).
e) Adjust the volume to a comfortable level.
f)
Go to Channel 20 using either the s/t keys (2).
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. PRESIDENT TOS-1)
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 15.75 inches /
40 cm, type President CA-2C).
b) To adjust the SWR meter:
- Set the CB on 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 t 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 ad-
justment of the antenna.
WARNING: In order to avoid any losses and attenuations in cables
used for connection between the radio and its accessories, PRES-
IDENT recommends to use a cable with a length less than 118.11
inches (3 m).
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 VOL knob (1) clockwise.
If the KEY BEEP function is activated, 4 tones sound when you
turn the CB radio on. Display shows during 1 second the current
microphone type.
See § KEY BEEP and § MICROPHONE TYPE on page 9.
b) To increase the sound level, turn the same knob further clockwise.
2) CHANNEL SELECTOR: s/t keys
These keys allow increasing or decreasing a channel. A «beep»
sounds each time the channel changes if the KEY BEEP function
is activated. See § KEY BEEP page 9.
3) ASC (Automatic Squelch Control) / SQUELCH
Suppresses undesirable background noises when there is no com-
munication. 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 (3) anti-clockwise into ASC position.
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. SC» disappears from the display.
b) MANUAL SQUELCH
Turn the SQ knob (3) clockwise to the exact point where all back-
ground noises disappear. This adjustment should be done with
precision as, if set to maximum (fully clockwise), only the strongest
signals will be received.
