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).

4.
DELTA TUNE
The Delta Tune is an electronic tuning circuit which allows you to shift the
frequency of your receiver plus or minus 1 KHz ( 2 KHz total).
This allows you to compensate for an incoming signal which may be slightly
off the center frequency. Adjust the Delta Tune circuit for maximum "S"
meter reading.
5.
AUTOMATIC NOISE LIMITER
Your ACT-2000 is equipped with a sophisticated electronic noise eliminator
system to greatly reduce extraneous noise coming into the receiver. In effect,
noise pulses are clipped from incoming signals before they reach the amplifi-
cation stage of the receiver. This causes no loss in the signal receive level. The
ANL circuit should normally be left on. A switch has been provided to
eliminate this circuit if desired.
6. PA-CB
In the "PA" position, your ACT-2000 is converted to a public address
amplifier or hailer. The PA function should not be used unless an 8-16 ohm
external speaker is connected to the "PA" Jack located on the back of the
chassis. Once this optional speaker has been connected, simply put the
PA-CB switch to the "PA" position and depress the microphone push-to-talk
switch.
NOTE: THE VOLUME CONTROL ADJUSTS PA OUTPUT LEVEL.
7.
S/RF METER
The ACT-2000 is equipped with a large, easy-to-read combination meter
with a built-in transmit and modulation light.
In the receive position, the meter reads the level of the incoming signals.
In the transmit position, it indicates relative power output. The intensity
of the light will vary with your voice to indicate modulation.
8. CHANNEL SELECTOR
The channel selector switch is used to select the fixed center frequency. It
automatically adjusts both the receive and transmit frequencies. Set the
selector switch to the desired channel.
9. PA SPEAKER JACK
For attaching optional 8-16 ohm PA speaker. Use 3.5 mm jack.

10. EXTERNAL SPEAKER JACK
You may add any 8-16 ohm external speaker. Simply plug your accessory
speaker into the jack. Inserting the 3.5 mm plug will automatically
disconnect the internal speaker.
11. ANTENNA CONNECTOR
A standard SO-239 type connector is supplied for attaching either mobile or
base antennas.
12.
DC POWER CORD
To attach to power source.
13. MICROPHONE
The receiver and transmitter are controlled by the press-to-talk switch on the
microphone. To transmit, simply press in this switch. Release the switch to
receive. When tra,nsmitting, hold the microphone 3 to 4 inches from your
mouth and speak clearly at normal voice levels.

POWER SUPPLY
Your ACT-2000 as supplied operates from a + 13.8V. DC power source
(EITHER POSITIVE OR NEGATIVE GROUND)
NEGATIVE GROUND HOOKUP:
Attach the red (fused) wire to the fuse block terminal or any convenient plus
(+) lead. Devices operated by the ignition key such as the radio, light etc.
are best since when you turn the ignition off, the unit will be turned off.
Attach the black lead to the car body via any convenient method.
NOTE: Many newer cars use plastic dash pieces. Make sure the screw or
contact you choose is attached to the metal framework of the car.
POSITIVE GROUND HOOKUP:
In the event that you do have a positive ground vehicle, the following hookup
must be made. Attach the red (fused) lead to the car body via any convenient
screw, bolt etc. Attach the black lead to the terminal block or any convenient
wire which goes to the minus (—) pole of the battery.
FAILURE TO MAKE THE PROPER CONNECTION CAN RESULT IN
UNIT DAMAGE.

ANTENNA REQUIREME
This transceiver will operate with any standard 52 ohm ground-plane, vertical,
mobile whip, long wire or other CB antenna. A standard SO 239 type
connector is provided on the back panel for use with popular PL 259 antenna
plug.
ANTENNA INSTALLATION
BASE STATION:
When the ACT-2000 is used
,
as abase station, any Citizens Band beam, dipole,
ground plane or vertical antenna may be used. A ground plane type will
provide greater coverage and, since it is essentially non-directional, it is ideal
in base station to mobile operation. From base station to base station, or
point to point operation, a directional beam will give greater distance even
under adverse condition. The range of the transceiver depends basically on
the height of the antenna and, whenever possible, select the highest location
within F.C.C. limits. (These regulations limit the antenna height to 20 feet
above an existing structure). Generally a maximum of 26 feet of lead-in
cable should be used due to line losses. However, a desirable antenna location
may justify the loss in extra lead-in-length.
MOBILE ANTENNAS :
A vertical whip antenna is best suited for mobile use. A non-directional
antenna must be used for best results in any case. The base loaded, whip
antenna will normally provide effective communication. For greater range
and more reliable operation, a full quarter-wavewhip should be used. Either
of these antennas use the metal car body as a ground plane and the shield
of the base lead as well as the metal case of the transceiver should
be grounded. A standard antenna connector (type SO 239) is provided on
the transceiver for easy connection to a standard PL 259 cable termination.

MOBILE INSTALLATIONS
A location in the car or truck should be chosen carefully for convenience of
operation and non-interference with normal driving functions. Mounting may
be under the dash or instrument panel or any place a secure installation can
be made. The carrying handle again serves as the mounting bracket or addi-
tional perforated straps or brackets may be used as desired. The 12 volt
cable may be connected to any convenient terminal but preferably to the
ignition switch to prevent unauthorized persons from operation of your
unit. With this method the unit will only operate when your key is turned
on. Engine ignition interference should not be a problem and vehicles
equipped with standard broadcast radios will have enough suppression to
eliminate ignition interference. If interference is present, any skilled auto
radio repairman should be able to eliminate it for you.
BASE STATION INSTALLATIONS
When a proper power supply is used, simply connect the red (+) and black
(—) terminals on the power supply to the (+) and (—) leads on your ACT-
2000. Do not attempt to operate this transceiver by connecting directly to
110 Volts AC.
