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 (
M
position).
e)
Adjust the volume to a comfortable level.
f)
Go to Channel 20 using either the «
UP» «DN
» key on the microphone or the
rotary knob (
6
).
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.
* Adjustment with the built-in SWR meter
- Set the CB to channel 20 in FM.
- Turn the
RF POWER
(
1
) to maximum,
- Put the switch (
15
) on the to position
CAL
(calibration).
- Press the «push-to-talk» switch (
18
) on the microphone to transmit.
- Bring the index needle to
of the Meter by using the calibration key
CAL
(
2
).
- Change the switch (
15
) to position
SWR
(reading of the SWR level). The reading
on the 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.
* Adjustment with an external SWR meter (e.g. TOS-1 PRESIDENT)
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 in FM.
- Turn the
RF POWER
(
1
) to maximum,
- Put the switch on the SWR meter to position
FWD
.
- Press the «push-to-talk» switch (
18
) on the microphone to transmit.
- Bring the index needle to
▼
,
∞
or
SET
by using the calibration key
CAL
.
- Change the switch to position
REF
(reading of the SWR level). The reading on
the 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 ~ RF POWER
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.
RF POWER
Adjustment of the output power in AM and FM mode only. Allows reducing
the power in case of a nearby communication with a person who has no
RF
GAIN
.
The normal position of this function is set to maximum, fully clockwise.
2) ASC (Automatic Squelch Control) SQUELCH ~ CAL
SQUELCH
Suppresses undesirable background noises when there is no communication.
Squelch does not affect 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 (
2
) anti-clockwise into
ASC
position. The
«ASC/VOX»
led lights up into green.
Note:
If the
VOX
function is also active, the led lights up into orange.
No repetitive manual adjustment and a permanent improvement in listening
comfort when ASC is active. This function can be disconnected by turning
the switch clockwise. In this case the manual squelch control becomes active
again. The
«ASC/VOX»
led turns off.
b)
MANUAL SQUELCH
Turn the squelch knob clockwise to the exact point where all background
noise disappears. This adjustment should be done with precision as, if set to
maximum (fully clockwise) only the strongest signals will be received.
