Controls and function

Antenna Connector.

This is a standard

BNC

high frequency connector

mounted on the top face of receiver.

VOL

(volume) control.

This is the inner knob of the

concentric controls on the top face of the receiver, and is used to

set the desired level of audio from the receiver. In its fully

anti-clockwise position, it turns off the power to the receiver.

8QL

(squelch) control.

The outer knob of the concentric controls,

the squelch control is provided to eliminate the background noise on

unoccupied frequencies, and also to enable the receiver to decide

whether or not to stop on a frequency when searching or scanning. Turn

the

SQL

control from the fully anti-clockwise position until the

background noise just disappears. This is the most sensitive setting

for the

SQL.

It is usually preferable to advance the squelch control

little way further clockwise than the most sensitive setting to avoid

inadvertent stopping on noise or very weak signals.

ATT (attenuator) switch.

For most uses, the

or long distance

setting is used for most sensitive condition for the receiver.

However, when operating the

ARlOOO

in the presence of very strong

signals such as those from TV stations or FM broadcast transmitters,

some interference effects may be apparent. This can take the form of

increase levels of background noise, or spitting noises occasionally

heard on peaks of modulation from the interfering source, or strange

spurious signals generated by intermodulation between the strong

signals. The cure of most of these effects is the use of the

ATT

switch in the

LOCAL

position.

UP/DOWN

knob.

This is-the tuning knob. For a full description of

the use of the knob.

EAR (earphone or external speaker).

This is used for connection

of either the earphone supplied, or an external headset or

loudspeaker. When a plug is inserted into this jack, the internal

speaker of the

ARlOOO

is automatically disconnected. The impedance of

the external load should be

ohms or greater.
