FEATURES AND CONTROLS
L
RF GAIN
NOTE: FOR NORMAL MAXIMUM RECEIVING RANGE THIS CONTROL
MUST BE IN ITS MAXIMUM POSITION (FULLY CLOCKWISE)
The
"RF
Gain" control lets you adjust the sensitivity (receiving range) of
your ACT-2000. For maximum range reception, the control should be
turned up to maximum (fully clockwise).
In some cases, you may find yourself operating within a very close distance
to another station. When extremely strong signals are present, they some-
times have a tendency to "overload" and distort. (Two mobiles within a
half mile driving down the same highway or a mobile driving past a base
station may generate this condition). While a wide range electronic AGC
circuit is incorporated in your ACT-2000, it cannot cope with the wide
variances that occur. This is the purpose of the RF Gain control. It lets you
manually adjust the receive capability to prevent distortion and overload on
strong signals. Should this condition occur, simply turn the RF Gain control
in
,
a counter clockwise position until the audio is clear and crisp.
REMEMBER -- FOR MAXIMUM RECEPTION, ALWAYS RETURN THE
CONTROL TO ITS MAXIMUM GAIN POSITION.
2.
SQUELCH CONTROL
The squelch control is used to eliminate background noise when there are no
signals present strong enough to overcome the noise. To adjust the squelch
control, select a channel where there is no signal. Turn the volume up to
'normal listening levels. Rotate the squelch control clockwise until the back-
ground noise disappears.
3.
VOLUME/POWER ON-OFF/PA
LEVEL
This combination
-
control supplies power to your ACT-2000 and adjusts
the receiver and PA volume. The switch should be turned clockwise from the
"Off" position. You will hear an audible "click". The channel dial And
meter will light. To adjust the volume continue advancing the control in
a clockwise position.
When you switch the "CB-PA" switch to the PA position, this control allows
you to adjust the level of the PA output. To increase PA output rotate in a
clockwise position. To decrease simply turn in a counter clockwise position.
For maximum PA output power the control must be in a maximum position
(fully clockwise).
