How To Use Your Cb - PRESIDENT JOHNSON II Manual Del Usuario

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 VOL (1) clockwise.
d) Turn the squelch knob SQ (2) to minimum (M position). Adjust the volume
to a comfortable level.
e) Go to Channel 20 using either the UP/DN (4).
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 t 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 VOL (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 commu-
nication. 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
Turn the squelch knob SQ (2) counterclockwise to ASC position. «ASC»
appears on the display. No repetitive manual adjustment and a per-
manent improvement in listening comfort when this function is active.
It can be disconnected by turning the knob clockwise, in this case the
manual squelch control becomes active again. «ASC» disappears.
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) DISPLAY
