[9] [I] [DEL]  Numeric 9 / Bank I / Data delete
This key acts as a numeric 9 when entering frequen- cies via the
keypad.
In search, scan and memory modes this key is used to identify bank I/i.
If the sequence [FUNC] [9] is keyed the data delete options menu and sub
menus may be accessed.  Initially the legend “SELECT DEL” is displayed on
the first line of the LCD.
Delete mode enables search, frequency pass, memory and select scan data to
be deleted easily.
[0] [J] [COPY]  Numeric 0 / Bank J / Copy (clone) between sets
This key acts as a numeric 0 when entering frequencies via the
keypad.
In search, scan and memory modes this key is used to identify bank J/j.
If the sequence [FUNC] [0] is keyed the clone data (copy) between sets
options menu is accessed and display legend “SET COPY” appears on the
LCD.  If EXPERT status has not been selected then a smaller number of
options are available.
Note: The RS232C REMOTE control optional interface (CU-8232) and lead will
be required to connect two AR8000 receivers together.
[.] [Aa] [P.WORD]  Decimal separator / Bank select /
Password banks
This key acts as a decimal separator when entering frequencies via the keypad
and signifies the MHz position.
i.e. For 133.7000 MHz the entry would be:
[1] [3] [3] [.] [7] [ENT]
There is no need to input the trailing “0” after the decimal as they will be added
automatically by the AR8000 microprocessor.
In search, scan and memory modes this key is used to change between the
two main blocks of banks signified by upper and lower case letters.  Standard
banks are A, B, C, D, E, F, G, H, I, J and banks which may be password
protected are a, b, c, d, e, f, g, h, i, j.
The password facility prevents preying eyes from accessing and reviewing your
bank data.
If the sequence [FUNC] [.] is keyed the bank PASSWORD menu is accessed

22
and the legend “SET P.WORD” is displayed on the first line of the LCD.
If the numbers “0000” are displayed then no password is set and all memory
banks are accessible.  If “****” is displayed then the password is set and only
the upper case banks may be accessed.  To access the password protected
banks, press [FUNC] [.] followed by your four digit password then [ENT].
To change the password press [FUNC] [.] followed by your current password
then [ENT].  Next press [FUNC] [.] followed by your new password then [ENT].
Switch the set Off/On and the new password will be in effect.
Note: Ensure that you are not in a password protected bank when you switch
the set Off or the password protection will be partially defeated.  Make a careful
note of your password or you may find yourself locked out !!
Should you become locked out, you may reset the microprocessor by holding
the [CLEAR] key while powering up the receiver.  Your memory bank and
search bank data will remain intact but any linked banks, frequency pass data
etc will be lost.
[LOCAL] [CONF]  LOCAL-REMOTE /
Configuration new user - expert
While the AR8000 is under computer control via the remote RS232C
connector, pressing the [LOCAL] key temporarily shifts the data input from the
computer keyboard back to the AR8000 numeric keypad.  Any input from the
remote RS232C connector will revert operation back to the computer.
If the sequence [FUNC] [LOCAL] is keyed the configuration menu is accessed
and display legend “INITIAL SET” appears on the LCD.
The three main options are:
BEEP ON/OFF
Keypad “beep” and “boop” confirmation tones.  These tones may be selected
or deselected by use of the UP/DOWN keys and [DIAL].
FUNC / 2ndF
This affects the way in which the FUNCTION (shift) operates to suit the
operators (your) preferences.
When in 2ndF setting, the side panel [FUNC] key need only be momentarily
pressed then released before the pressing a second keypad option.  A
continually flashing highlight cursor “F” indicates FUNCTION selection.
When in FUNC setting, the side panel [FUNC] key must be pressed and held
while a second keypad option is pressed.  The flashing highlight cursor “F”
indicates FUNCTION selection.
The default setting is “2ndF”.

NEWUSER / EXPERT
The default setting is NEWUSER (new user),  this is the initial recommended
setting.  If EXPERT status has not been selected then a smaller number of
options are available which simplifies operation when first exploring the
features and facilities of the AR8000.
[CLEAR] - Clear entry key
This key will cause data entry to be cancelled should a mistake be accidentally
typed and forces an escape from the menu “back to search, scan of VFO
mode” whichever had been previously selected.
There is no second function for this key.
Should you experience a programming / operational problem with the AR8000,
you may reset the microprocessor by holding the [CLEAR] key while powering
up the receiver.  Your memory bank and search bank data will remain intact
but any linked banks, frequency pass data etc will be lost... use only as a last
resort.
[PASS] [S SET]  Frequency-channel pass (skip) /
Select Scan / Step offset
This key has many operations depending upon the condition of the receiver at
the moment it is operated:
In Search mode
When the search process stops on an unwanted busy channel (noise etc)
press the [PASS] key to register the frequency as a PASS (lock out) frequency.
Any subsequent search of the search bank will not stop at this frequency, it will
be skipped.
To edit the search pass frequencies press [FUNC] [PASS].
In MEMORY RECALL or SCAN mode
PASS - In the “M.RE” (memory recall) mode or when the scan stops on a
channel, press [PASS] to register the memory channel as a “PASS CHAN-
NEL”.  The letter “p” will be added to the left of the frequency to indicate the
channel will be passed (skipped).  To release the pass status, press [PASS]
again while in M.RE mode, this will remove the letter “p” and reinstate the
channel so that it may be scanned along with other channels in the memory
bank.
Note: If you PASS a memory channel which is currently “tagged” for SELECT
SCAN, the letter  “p” will be hidden behind the letter “s” for select scan.
SELECT SCAN - In the “M.RE” (memory recall) mode or when the scan stops
on a channel, press [FUNC] [PASS] to “tag” (register) the memory channel as
a “SELECT SCAN CHANNEL”.  The letter “s” will be added to the left of the
frequency to indicate the channel has been added to the current SELECT

24
SCAN list.
To toggle the status of select scan, press [FUNC] [PASS] again while in M.RE
mode.
Select scan only scans those specific channels which have been tagged
(registered) using the [FUNC] [PASS] select scan procedure.  This is very
useful to allow the rapid selection of a mixture of memory channels irrespective
of memory banks for specific scanning applications.
In 2VFO mode
PASS - While in 2VFO mode, press [PASS] to edit the search pass
frequencies (just as with [FUNC] [PASS] while in search mode).
SELECT SCAN - While in 2VFO mode, press [FUNC] [PASS] to quickly
review, locate and edit the contents of select scan in a “similar” manner to
using [FUNC] [PASS] while in M.RE mode to tag channels for select scan.
[ENT] - Enter key
The enter key is used to finalise the entry of frequency and other data inputs.
While in 2VFO mode, press and hold the [ENT] key to add the currently
displayed frequency into memory through a small menu.
While in SEARCH mode and stopped on a busy channel, press the [ENT] key
to cancel search and remain on the currently displayed frequency.
5-8 Loudspeaker (internal)
The AR8000 is fitted with an internal front facing loudspeaker toward the upper
front cabinet.  When an external earphone, headphone or speaker is connected
the internal speaker is automatically disconnected.
Side panel - left hand side
5-9 [FUNC] Function key
FUNC / 2ndF
The AR8000 uses a multi-function keyboard.  The function (shift) key is used to
access the second key functions as listed underneath the keypad keys.  Other
functions may also be accessed using the function key.
When the function key is operated, a flashing highlight cursor “F” in the lower
left of the LCD indicates activation.
There are two ways in which the [FUNC] key may be operated to suit the
operators preferences.  The setting of [FUNC] is made in the CONF-configura-
tion menu accessed in 2VFO mode by pressing [FUNC] [CONF].

When in 2ndF setting, the side panel [FUNC] key need only be momentarily
pressed then released before pressing a second keypad option.  A continually
flashing highlight cursor “F” indicates FUNCTION selection.
When in FUNC setting, the side panel [FUNC] key must be pressed and held
while a second keypad option is pressed.  The flashing highlight cursor “F”
indicates FUNCTION selection.
The default setting of the [FUNC] key is “2ndF”.
5-10 [MONI] monitor (squelch defeat) key
This key is used to defeat the squelch (open it) to allow the
monitoring of very weak of fluttering signals.
5-11 [LAMP] lamp - LCD, keypad & side panel illumination
Attractive green rear illumination of the LCD (and keypad /
 side panel) is switchable for use in locations of low level lighting.
Press the [LAMP] key to activate.  The illumination will be active for about five
seconds then will automatically switch Off in order to conserve battery power
(use the lamp facility sparingly when powered from batteries).  Should data be
keyed in, the five second timer will count from the last key press...  this
eliminates any requirement to rush data input.
The five second illumination may be cancelled by pressing [LAMP] a second
time.
It is possible to switch the illumination On permanently for mobile operation
etc.  The input regulator is deliberately overrated to allow for permanent
illumination.  To activate permanent illumination press [FUNC] [LAMP].  The
illumination may still be switched Off by pressing [LAMP] which returns the
facility to timer operation.
The lamp is driven by an internal voltage inverter circuit so that the level of
lighting should not drop as battery voltage changes due to exhaustion (should
not dim).  Of course the lamp illumination will cease to function when the
batteries are fully exhausted requiring recharging.
5-12 [K.LOCK] Keypad lock
The keypad and [DIAL] may be electronically locked during
use to prevent accidental change of frequency, mode etc.
This is useful when one particular frequency is being monitored
(such as an airshow) and the receiver is in a pocket.
To activate keylock press [K.LOCK].  The legend “KLCK” appears in the upper
left corner of the LCD to confirm keylock operation.
To deactivated keylock for normal operation press [FUNC] [K.LOCK].

Side panel - right hand side
5-13 DC 12V Charging / external power connection
This is a standard 1.3mm dual concentric DC socket.  The wiring of this socket
is CENTRE POSITIVE, negative ground.  THE AR8000 MUST NEVER BE
CONNECTED DIRECTLY TO THE MAINS SUPPLY.
The DC socket is used to charge the internal NiCad batteries using the charger
provided.  The receiver may also be connected to an external 12V DC supply
for powering away from home (such as to a vehicle 12V cigar lighter socket
using the DC lead).
The AR8000 may also be connected to a separate regulated DC power supply
for use at home.  The rating of the regulated power supply must be a nominal
12V DC @ 300mA or higher current rating.

Rear case
The battery compartment cover (which is located to the lower section of the
rear case) may be removed using a downward sliding motion.  Underneath the
battery compartment cover are two user accessible parts, the RS232C-
REMOTE/TAPE connector and the BATTERIES.
5-14 RS232C REMOTE connector
This is a very small connector located at the very lowest point of the rear
cabinet below the battery housing.  It may not be immediately obvious that this
is a connector, a channel of about 10mm wide by 3mm high houses the
connector.
An optional interface (CU-8232) and lead is available which connects to this
point to permit cloning (copying) of data between two AR8000 receivers and
computer control of the unit.
A separate optional interface (CR-8000) permits tape record connection for
both audio and motor switching.
5-15 BATTERY compartment
Inside the battery compartment is a cradle designed to accept 4 x UM-3 (AA
size) batteries.  Carefully note the polarity of the cells (which way around they
fit).  Either the supplied rechargeable NiCad batteries or high quality dry
batteries may be used.  However, never attempt to charge the receiver or
connect to an external power source when dry batteries are fitted.
Always remove dry batteries when they have expired (run down).  Should you
plan not to use the receiver for a period of time and have dry batteries fitted,
remove the batteries to avoid leakage.
Note: The memory channel data is held by an internal EEPROM which
does not require batteries or connection to external supply.  However,
always switch the receiver Off when changing batteries or connecting /
disconnecting external power.  Should you remove the batteries while the
set is switched On the last memory data will be lost.
* Please refer to section 4-3 POWER REQUIREMENTS for further details and
charging information.

(6) Basic manual operation of the receiver
Operating manual conventions
Where text appears in [SQUARE BRACKETS] the keys are to be pressed
exactly as shown.
For example:  [1] [4] [5] [ENT]
Means press the 1 key followed by the 4 key followed by the 5 key followed by
the enter key.
Words contained in speech marks “2VFO” refer to indications displayed on the
Liquid Crystal Display.
Sections of “italic text” indicate an advanced function or facility only available
when in EXPERT rather then NEWUSER (new user) mode.
6-1 Before starting
Before operating,  charge the internal NiCad batteries using the supplied
charger for approximately 16 hours.  Connect the supplied flexible aerial
to the BNC connector.
Note: When the receiver is switched OFF, all VFO data will be automatically
stored into EEPROM memory storage.  No battery or capacitor is required for
memory backup.  Should the NiCad (or dry batteries if in use) cells become
completely exhausted, the last stored memory channel or last VFO data “may”
be lost.
CURSOR
The CURSOR may apparently “go to sleep” at times when menus are called.
This is because of the many tasks called by the microprocessor, it is simply
doing something else at the time you call it.  Should this happen, press
[CLEAR] to escape the menu and re-select the menu again.
6-2 Switching On
Set the squelch control to the 12 o’clock position.  Rotate the volume control to
the 12 o’clock position, this action will also switch the set on (a click will be
heard / felt as the control passes the 9 o’clock position).  It is never a good
idea to switch On the receiver with an earphone connected, there may be an
audible click when the unit is switched On or the volume may be accidentally
set uncomfortably high.
The LCD will show the opening message “WELCOME TO THE WORLD
OF AR8000 RECEIVER” across the first four lines, at the same time the
microprocessor generates the “boot up data” required to control the receiver.
