(frequencies such as 1.215 MHz = 1215 kHz).  If signal strength appears weak,
try rotating the receiver as the bar aerial is directional.
The internal ferrite bar aerial should provide adequate results in city and
high population areas or when visiting airshows which operate a
commentary service on medium wave.  Better results may be achieved
by using an external aerial.
It is not possible to further increase sensitivity on medium wave firstly due to
the up-conversion receive...

the ATU when changing frequency.  An ATU of this type has no active circuitry
so is known as a passive device.
Active desktop loop aerials
Usually designed for the shortwave bands (such as the AOR LA320). Loop
aerials have the advantage of small size when compared to long wire aerials
and being within easy reach of the operator it can be rotated to provide
directivity.  The circuitry offers a small level of gain with the advantage of
selectivity similar to an ATU.

5-2 EAR - Earphone / speaker connection
This 3.5mm mono socket permits connection to an external earphone, headset
or speaker of 8 OHM impedance or greater.  When this earphone socket is
used, the internal speaker will be automatically disconnected.
5-3 DIAL - tuning control / selector
The DIAL control is prominently located on the top of the
cabinet for ease of use.  This control changes the received
frequency up and down in whatever step increment is selected and operates as...

5-5 PWR / VOL - On/Off switch and volume control
The combined volume control and power switch is located on
the top face of the cabinet.  This control is used to set the required
audio output from the receiver.  When rotated fully clockwise the volume is at
maximum, when rotated fully anticlockwise the volume is reduced to minimum.
At the fully anticlockwise position the power On/Off switch is activated with a
“click”.

switchable for use in locations of low level lighting.
The  basic  operational description of each key is as follows:
[SRCH] - search key
When first pressed initiates the search process and “SRCH” is displayed at the
top left of the LCD.
When [SRCH] is pressed a second time during search, the SEARCH process
is cancelled and the current search frequency is left as a single frequency
readout on the LCD.  This can be useful should you wish not to have 2-VFO
display but wish for a...

[2-VFO] [A=B] - twin VFO / equalise memory /
manual search key
The AR8000 receiver has a 2 VFO system being identified as “A” and “B” on
the LCD to the left of the frequency readout.  The term VFO historically means
“Variable Frequency Oscillator” and today refers to a tunable data store which
contains frequency, mode, channel step, step offset and attenuator informa-
tion.
Both VFO frequencies are displayed in parallel format on the LCD one above
the other....

should a permanently busy channel be encountered.  The UP and DOWN keys
may be used to force the receiver to continue searching from a busy channel
and to reverse the direction of search.
While in search or scan modes and stopped on an interesting busy channel,
press [FUNC] [2VFO] to transfer the busy channel to the “active” VFO and
revert to VFO mode.
To return to 2VFO mode, press the [2VFO] key.
Should you prefer only a single frequency to be displayed press [SRCH]

[2] [B] [STEP]  Numeric 2 / Bank B / STEP key
This key acts as a numeric 2 when entering frequencies via the keypad.
In search, scan and memory modes this key is used to identify bank B/b.
If the sequence [FUNC] [2] is keyed, the tuning STEP size may be
selected.
[3] [C] [MODE]  Numeric 3 / Bank C / MODE key
This key acts as a numeric 3 when entering frequencies via the keypad.
In search, scan and memory modes this key is used to identify bank C/c.
If the sequence [FUNC] [3] is...

[6] [F] [S PROG]  Numeric 6 / Bank F / Search program
This key acts as a numeric 6 when entering frequencies via the keypad.
In search, scan and memory modes this key is used to identify bank F/f.
If the sequence [FUNC] [6] is keyed, the SEARCH PROGRAM menu will be
activated.  The legend “SRCH PROG” appears on the top line of the LCD to
indicate activation.  The data programming or  reprogramming of search banks
may be input through this menu.
While in VFO and search program...
