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
knob (
2
) to minimum (anti-clockwise). Adjust the volume
to a comfortable level.
e)
Go to Channel 20 using either the «
UP
» «
DN
» key on the microphone or the
rotary knob (
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.
* Using an external SWR meter (e.g. SWR 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 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
.
- Press the «push-to-talk» switch on the microphone to transmit.
- Bring the index needle to
t
,
∞
o SET by using the calibration key
CAL
.
- Change the switch to position
REF
(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.
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 back-ground noises when there is no communication.
Squelch does not effect neither sound nor transmission power, but allows a
considerable 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 com-
munications RF GAIN should be set to maximum. RF GAIN can be reduced
to avoid distortion, when your correspondent is close by and when he does
not have RF POWER.
The normal setting of this knob is on maximum (fully clockwise).
4) MIC GAIN
Is for regulating microphone sensitivity, when using a microphone other than
the one supplied with your PRESIDENT WALKER ASC. (pre-amplified).
The normal setting of this knob is fully clockwise.
5) CHANNEL SELECTOR: Keys «DN» and «UP» on microphone
and ROTARY knob
The two keys, «
UP
» and «
DN
» on the microphone allow you to go up and
down the channels. This can also be done using the channel rotary knob (
5
).
You can select the channel (1 to 40) of reception or transmission.
