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 on the front panel.
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 or 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.
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) 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.
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) CHANNEL SELECTOR ROTARY KNOB
Turning this knob allows you to choose a channel (1-40) for transmitting and
receiving. A beep is heard every time the channel is changed.
4) DISPLAY
The display shows all the different functions. The S-METER shows the level of
reception and the level of power emitted.
5) MODE
Use this key to select AM or FM. The modulation mode must correspond with
that of the person with whom you communicate.
A/
Amplitude Modulation (AM) is for communications in areas where there
are obstacles and over medium distances.
B/
Frequency Modulation (FM) is for nearby communications in flat, open
areas. It gives better quality of communication (squelch adjustment needs
more finesse).
