Controls and function
1. Antenna Connector. This is a standard BNC high frequency connector
mounted on the top face of receiver.
2. 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.
3. 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.
4. ATT (attenuator) switch. For most uses, the DX 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.
5. UP/DOWN knob. This is-thetuning knob. For a full description of
the use of the knob.
6. 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
8 ohms or greater.

easy to understand form.
CHG. This concentric socket is mounted on the side of the case and
is used for connection of the mains charger supplied, or the
DC power
cord supplied, or any suitable
11 to 14 volt DC supply.
Xeyboard controls
1. First of all we have the numerical keys from 0 to 9, plus the
decimal point
(.). These are used for entering frequency, frequency
step size, memory channel number, bank number, and so on. The same
keys are used in the bank select mode, in which case the numbers
0 to
9 correspond to the frequency bands listed in the operating paragraph
of this handbook. The bank designations are show on the lower side of
each number key.
2. CLEAR.(.) Press once to enter a decimal point when entering
frequency information. Press twice to clear an incorrect entry.
3. ENTER key. Used to enter frequency after selection by the keypad,
or to complete many memory changes or operations.
4.
SEARCH key. Used to start the frequency search action of the
receiver; also used to manually advance frequency after the search has
stopped.
5. SCAN key. Used to start the memory scanning system of the receiver;
also used to manually advance the memory channels when the scan has
stopped.
6. MANUAL key. Used to engage the manual mode of receiver control,
'9
at is when the user wishes to directly enter a frequency of interest
to the receiver, or directly select any memory channel.
7. PROG key. Used in programming search frequency limits.
8.
LIMIT key. Used in conjunction with the PROG key in fixing search
band limits.
INC key. Used when entering the desired frequency increments or
Ls , from 5KHz to 995KHz.
10. Bank key. Used to select the desired memory bank or search bank
from
0 to 9 when scanning or searching.

11. AM/FM key. Selects either mode as required.
12. W-FM key. Selects either W(wide)FM or narrow FM as required.
13. LOCKOUT key. Press once to lockout the channel or frequency show
on the display.
14. DELAY/HOLD key. Press to change from DELAY to HOLD and back again
sequentially in both search and scan mode. When
"HOLD" is shown on the
display, the scan or search stops on a busy channel and remains there
even after the signal has gone off. When
I1DELAY" is shown on the
display, the scan or each stops on a busy channel, but then
automatically resumes the search or scan approximately
2 seconds aft
the signal has gone off.
15. Down arrow key Initially, the search or scan action is always from
lower frequencies to hiqher, or lower memory channels to higher. If
when searching or scanning, the down arrow key is pressed, the search
or scan stops, and the down arrow mark is shown on the display.
Subsequent short press of the down arrow key will step the scan or
search downwards. If the down arrow key is held pressed for more than
about one seconds, the scan or search will re-start, but in the
downwards direction.
16. KEY LOCK key. Press this key to disable all keyboard function.
Press again to restore all function to normal. This key is used to
prevent accidental mis-operating or changes of frequency when the
receiver is being carried around but still in use, for example at air
displays.
17. LIGHT key. Pressed momentarily, this will illuminate the display
for approximately six seconds, after which the lamp will automatically
be extinguished.
