PRESIDENT ELECTRONICS PRESIDENT JFK II ASC [31/56] 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 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 channel selectors (5).
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 in FM.
- 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
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 (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 maxi-
mum (fully clockwise), only the strongest signals will be received.
3) RF GAIN
Adjustment of the sensitivity during reception. For long distance communi-
cations RF GAIN should be set to maximum. You can reduce the RF GAIN in
order to avoid distortion when your correspondent is close by and when he
has no RF POWER.
The normal setting of this function is on maximum (fully clockwise).
4) RF POWER
Adjustment of the output power in AM and FM mode. Allows reducing the
power in case of a nearby communication with a person who has no RF
GAIN.
The normal position of this function is set to maximum, fully clockwise.
