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 (6 A) 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 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 President 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 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 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) MODE:
Use this key to select AM, FM, LSB or USB.
The mode must correspond with that of the person with whom you
communicate.
Amplitude Modulation (AM): The most used.
Frequency Modulation (FM) is for nearby communications.
Lower and Upper Side Band is used for communications over long distances
(depends very much on atmospheric conditions).
4) MOD-S/RF:
MOD position: View-meter indicates the average percentage of modulation.
S/RF position: View-meter indicates relative transmitter output power when
transmitting and input signal strength when receiving.
