How To Use Your Cb; Use - PRESIDENT Johnson Manual Del Usuario

to connect the power cable directly to the battery (as the connection of the
CB cable to the wiring of the car-radio or other parts of the electrical circuit
may, in somecases, increase the likelihood of interference).
d) Connect the red wire (+) to the positive terminal of the battery and the black
(-) wire to the negative terminal of the battery.
e) Connect the power cable to your CB radio.
WARNING: Never replace the original fuse (5A) by one of a different value.
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 knob VOLUME clockwise.
d) Turn the SQUELCH knob to minimum (anti-clockwise). Adjust the volume to a
comfortable level.
e) Go to Channel 20 using either the «CH ▲» «CH ▼» key on the microphone or
the rotary knob.
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 or SWR 2):
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 CA 2C).
b) To adjust the SWR meter:
- Set the CB to channel 20.
- Put the switch on the SWR meter to position CAL ou FWD.
- Press the «push-to-talk» switch on the microphone.
- 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 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.
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 are no communica-
tion. 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 ac-
tive again.
b) 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).
