direction program search was previously using.
Delete program search bank data while in VFO mode
First place the receiver into the 2VFO operating mode by pressing [2VFO].
Access the main “SELECT-DEL” by keying [FUNC] [9].  Use the UP/DOWN or
[DIAL] to position the cursor to the left of the “SRCH-DATA” option then press
[ENT].
Use the keypad, [DIAL] or UP/DOWN keys until the desired bank identifier is
displayed.  Remember, if you have set the password then it must be keyed in
to access the protected banks.
When the desired program search bank identifier is displayed, press [ENT] to
delete the data.
The receiver will return to 2VFO mode.
(14)   FREQUENCY PASS (lockout)
Should the AR8000 stop on an active frequency while in program search mode
and you do not wish to monitor it any longer, simply press the UP/DOWN keys
or rotate the [DIAL] to force the search process to resume in the direction
selected.
However, should the receiver continually stop on the same frequency you may
wish to PASS (lockout) the annoying frequency so that it will be skipped over
when the bank is next searched.  Even STEP-OFFSET frequencies may be
passed.
Up to a total of 50 memory channels may be “passed” in each of the 20
program search banks making a total of 1000 locked out frequencies.
Note: To prevent the same frequency using up many pass channels, the
AR8000 will not permit the same frequency to be registered for PASS
within a range of +/- 10 kHz from a previously locked out frequency.
14-1 FREQUENCY PASS (lockout) during program search
To PASS a frequency when searching, wait for the frequency to become active
then press [PASS].
A lower case (small) letter “p” will be added to the left of the frequency display
on the second line and the scan process will move on to the next frequency.
This process will happen so quickly that you will not see the “p” for
PASS being added.  However, should you subsequently review the
frequencies later, the legend “p” will be displayed along side the frequency. 
						

							AR8000 operating manual
92
14-2 FREQUENCY PASS (lockout) using the “FREQ PASS” edit menu
New frequencies may be manually added to the frequency pass list and
existing frequencies edited or deleted.
The “FREQ PASS” menu is accessed while in SEARCH mode using the
sequence [FUNC] [PASS].
The “FREQ PASS” menu displays the legend “FREQ
PASS” on the top line to confirm operation.
The second line of the LCD will display the legend
“BANK” followed by the search bank identifier to the
right.  The highlight cursor will be flashing over a
search bank identifying letter (the current search bank
parameters will be displayed on the fourth line of the
LCD in a scrolling format, if there is no data
programmed the data areas will display “- - -”).
Select the search bank identifying letter for the bank you have chosen (if you
are searching bank “B” then select “B” now).  This may be selected using the
[DIAL], keypad or UP/DOWN keys.  When the required bank identifier is
displayed (“B”) press [ENT] to select the bank for editing.
The left side of the second line of the LCD displays “BANK B00” or the first
pass channel in the selected bank.  The fifty pass channels are numbered 00
to 99.
The highlight cursor flashing on the first letter “P” (for PASS) to the left of the
third line of the LCD.  To review the contents of the PASS list rotate the DIAL.
The pass channel number will be displayed on the second line of the LCD.
14-3 Deleting (cancelling) a single PASS frequency
It is possible to delete a frequency from the pass list so that it will be searched
again (no longer passed / skipped / locked out).
To delete a frequency select the corresponding pass channel location (as
described in section 14-2 - in search mode [FUNC] [SRCH] select letter [ENT]
rotate [DIAL] to select frequency) so that the frequency is displayed to the right
of the letter “P”.
Key in a new frequency of null value [0] using the keypad (the entry of [0] will
delete the chosen pass channel) then press [ENT].
The data in the pass list will “shuffle” down to fill the empty channel and a
vacant channel will appear at the top of the list. 
						

							AR8000 operating manual
93
14-4 Changing (editing) a PASS frequency
It is possible to edit a frequency contained in the pass list.
To edit a frequency in the pass list (a pass channel) select the corresponding
pass channel location (in search mode [FUNC] [SRCH] select letter [ENT]
rotate [DIAL] to select frequency which you wish to change).  The frequency
you wish to change will be displayed to the right of the letter “P”.
Key in the new frequency (say 433.200 MHz [4] [4] [3] [.] [2]) then press
[ENT].
The new frequency data will over-write the existing data and the display will
move on to the next channel.
To return to search mode press [CLEAR].
14-5 Manually entering a new PASS frequency
It is possible to enter a new pass frequency directly to the pass list.
For example, to manually enter the pass frequency of 433.300 MHz carry out
the following:
Ensure the receiver is in SEARCH mode, if not then press [SRCH].
Access the “FREQ PASS” edit menu using the sequence [FUNC] [PASS].
Select the desired search / pass bank identifying
letter using the [DIAL], UP/DOWN keys or keypad
then press [ENT].
The third line of the LCD will show the letter “P” plus
a frequency or blank data field “- - -”.  Rotate the
[DIAL] until the first vacant pass channel is located,
the vacant pass channel will have the display
“P - - - -”.
Key in the frequency which you wish to PASS, in our example this is [4] [3] [3]
[.] [3] then press [ENT].  The new pass frequency data will be written to the
pass list and the frequency will be passed (skipped) when that bank is next
searched.
To return to search mode press [CLEAR].
14-6 Entering a new PASS frequency while in MANUAL SEARCH
It is possible to write frequencies to the pass list when in MANUAL SEARCH
between VFO frequencies.  However, the frequency will not be actually passed
(skipped) while in MANUAL SEARCH.  The frequency will have to be manually
re-keyed into a chosen pass bank / channel. 
						

							AR8000 operating manual
94
This may be useful when carefully evaluating frequency bands using manual
search and specifically selecting pass frequencies before moving on to
automatic program search.
During search mode the receiver may stop on an unwanted frequency,
carefully note the frequency and if necessary write it down on a piece of paper.
 Press [PASS] to directly access the “FREQ PASS” menu.
Select an appropriate search bank identifying letter using the [DIAL], UP/
DOWN keys or keypad then press [ENT].
The third line of the LCD will show the letter “P” plus a frequency or blank data
field “- - -”.  Rotate the [DIAL] until the first vacant pass channel is located, the
vacant pass channel will have the display “P - - - -”.
Key in the frequency which you have previously noted press [ENT].  The new
pass frequency data will be written to the pass list.
Remember, the frequency will not be passed (skipped) in manual search mode
but it will be passed when the specified bank is next searched using program
search.
To return to manual search mode press [CLEAR].
14-7 Deleting all pass frequencies from a pass bank
It is often convenient to delete all pass frequencies from a bank in one
operation.  While this may be accomplished by deleting each and every pass
channel individually a faster method is available especially if you have
previously stored data into all 50 pass channels.
Press [2VFO] to enter 2VFO mode.  While in 2VFO mode press [FUNC] [9] to
access the “SELECT DEL” menu.
Use the UP/DOWN keys or [DIAL] to move the cursor to the left of the “FREQ
PASS” option.  Press [ENT] to select the option.
The highlight cursor will be flashing over a pass bank identifying letter.  Select
the required pass bank using the UP/DOWN keys,  [DIAL] or keypad. When
the required bank identifying letter is displayed press [ENT] to delete the data
contents.
The display will return to 2VFO mode.

(15)  AUTO STORE - automatic memory write from
program search mode
The AR8000 features an Automatic memory write facility.
AUTO STORE automatically writes the frequency, mode, step, step offset,
attenuator and comment of the first 50 “active” frequencies located in any
program search to memory bank “J”.  In default status as shipped from the
factory and when in NEWUSER mode the AUTO STORE facility is switched
“ON”.
This is particularly useful for locating interesting “active” frequencies during
program search especially when left unattended.
If you had left the unit unattended while program searching, you need only
check the memory channels of bank “J” to see the first 50 frequencies which
had become active while you were unavailable.  This memory bank may then
be scanned to further analyse the results or the frequencies “copied, moved or
swapped” to more appropriate memory banks / channels.
Note:  Frequencies less than +/- 10 kHz of a previously stored frequency will
not be automatically stored.
In EXPERT status, you may choose to switch the AUTO STORE facility ON/
OFF.
15-1 Using AUTO STORE in NEWUSER status
In NEWUSER status as shipped from the factory the AUTO STORE facility is
switched “ON” and memory bank “J” is used to store the data located in
program search mode.
When you first wish to use the facility, it is best to delete the contents of
memory bank “J” (where the search frequencies will be automatically saved to
memory) in order to provide meaningful information.
Only the first 50 “active” frequencies will be automatically stored and will be
written to memory in ascending memory channel order from 00 - 49 until all 50
channels have been used.  Active frequencies located after the 50th channel
has been used will not be stored.  This limitation is to prevent unnecessary
writing to the EEPROM data store.
Deleting ALL channels of memory bank “J” before AUTO STORE
First place the receiver into the 2VFO operating mode by pressing [2VFO].
Access the main “SELECT-DEL” by keying [FUNC] [9].  Use the UP/DOWN or
[DIAL] until the cursor is to the left of the “MEMO-DATA” option then press
[ENT]. 
						

							AR8000 operating manual
96
The top line of the LCD will display “MEMO-DATA” the second line will display
“DELETE” and the fourth line will display “BANK SET” to ensure that you are
aware of exactly the sub menu selected so that accidental memory bank
deletion is not possible.
The cursor will be positioned over the memory bank identifier (LETTER) to the
right of the legend “BANK”.  Use the [DIAL] or keypad to select memory
channel “J” which is to be deleted.
Press [ENT] to delete the entire contents of memory bank “J”, the receiver will
return to 2VFO mode.
Deleting selected channels of memory bank “J”before AUTO STORE
Although it is advised that ALL memory channels of bank “J” are deleted before
starting AUTO STORE, it is not absolutely essential.  As long as some empty
channels are available then auto store will operate.
To delete a few selected channels only, first place the AR8000 into “M.RE”
mode by switching on the receiver and pressing the [SCAN] key once (unless it
is in SCAN mode in which case you should press [2VFO] followed by [SCAN]).
Select the memory channel which you wish to delete by rotating the [DIAL].
The numeric keypad may be used to change the memory bank (identifier A, B,
C etc).  The UP / DOWN keys may also be used to select the memory channel.
Alternatively you may enter the memory channel in full via the numeric keypad.
For instance, to recall memory channel “J31” press [0J] [3] [1] [ENT].
Once recalled, to delete the memory data from memory channel “J31” press
[FUNC] [9].
The memory channel will be deleted and the display will move upward or
downward (depending upon whether the [UP] or [DOWN] keys had been
previously used or direction of rotation of the [DIAL]) to the next memory
channel number which contains data.
Starting AUTO STORE
Place the receiver into program search mode by pressing [SRCH].  Select any
search bank containing data and allow the set to search and find “active”
channels.
Memory channels of bank “J” will be automatically written to.
Reviewing automatically stored memory channels
You may review the frequencies which have been written automatically to
memory by entering MEMORY RECALL MODE. 
						

							AR8000 operating manual
97
First place the AR8000 into “M.RE” mode by switching on the receiver and
pressing the [SCAN] key once (unless it is in SCAN mode in which case you
should press [2VFO] followed by [SCAN]).
Select memory bank “J” by pressing the bank identifier via the keypad [0J].
The [DIAL] or UP / DOWN keys may be used to review the memory channel
data.
What to do with the automatically stored data
Once data has been stored, it may be deleted (as described earlier in this
section), scanned by pressing [SCAN] [J] or MOVED to another memory bank
and channel (see section 8-5 of this manual) to form the basis of a useful data
bank.
15-2 Switching AUTO STORE OFF/ON in EXPERT status
In EXPERT status, the CONFIGURATION menu is used to switch the AUTO
STORE facility ON or OFF.
To access the configuration menu press [FUNC] [LOCAL].  Make sure that the
EXPERT status is selected, if not use the UP/DOWN key to move the cursor
alongside the “NEWUSER” option and rotate the  [DIAL] so that the legend
“EXPERT” is displayed.
Press the [DOWN] key one further time until the
option “AUTO-STORE BANK-J STORE ON” is
displayed.  To disable the AUTO STORE facility,
rotate the [DIAL] until the option “OFF” is displayed.
Press [ENT] to accept the new parameters and
return to SEARCH, SCAN or VFO mode (which ever
was previously in use).
(16)  POWER SAVE programming in EXPERT status
The AR8000 has a POWER SAVE facility to enable the receiver to operate for
longer periods of time between battery recharging.  Power save is default OFF
in NEWUSER status to save any possible confusion while the receiver is in a
“dormant” cycle.
When power save is ON, the receiver will automatically switch On and Off but
the display will appears permanently On. Only the AR8000 “receive” circuitry is
switched On and Off (switching the receiver off for short periods of time is what
saves power!), the microprocessor is left On permanently.
When activated while in EXPERT status, two parameters may be changed to
affect the way the receiver monitors when in VFO mode, these are “DELAY”
and “CYCLE”. 
						

							AR8000 operating manual
98
DELAY: This parameter determines how soon the receiver will become
“dormant (then cycle)” and is timed from when the squelch last closed or
keypad was used.
The available range is 1 to 99 seconds plus OFF
selected by rotating the [DIAL] (default is OFF in
NEWUSER mode).  When OFF, the power save
does not operate and the data field of CYCLE will be
displayed as “- -”.
CYCLE: This parameter determines how long the
receiver will remain active looking for activity then
remain dormant.  The available range is 2 to 9
seconds selected by rotating the [DIAL] (default 3
seconds when the power save is On).
16-1 Changing POWER SAVE values
In EXPERT status, the CONFIGURATION menu is used to program the
POWER SAVE parameters.
To access the configuration menu press [FUNC] [LOCAL].  Make sure that the
EXPERT status is selected, if not use the UP/DOWN key to move the cursor
along side the “NEWUSER” option and rotate the  [DIAL] so that the legend
“EXPERT” is displayed.
Press the [DOWN] key until the “POWER SAVE” menu is displayed.  There are
two parameters which may be altered.
Use the UP/DOWN key to select the “DELAY” option.  Rotate the  [DIAL] to
choose the value in the range 1 to 99 seconds or OFF.
Use the UP/DOWN key to select the “CYCLE” option.  Rotate the  [DIAL] to
choose the value in the range 2 to 9 seconds.
Press [ENT] to accept the new parameters and return to SEARCH, SCAN or
VFO mode (whichever was previously in use).

(17)  SPECIAL functions
There are five “special” programmable functions available so that you may
further optimise the receivers performance.
THESE ARE FACTORY SET SO ONLY ATTEMPT TO CHANGE THEM IF
YOU ARE CONFIDENT OF THEIR EFFECT.  MAKE A CAREFUL NOTE OF
THEIR CURRENT POSITIONS BEFORE YOU ATTEMPT TO CHANGE THEM
AS THE DEFAULTS SHOWN LATER ARE SUBJECT TO CHANGE.
The options are selected by holding the [FUNC] key plus a numeric key
while switching the receiver On.  Wait for the sign on message to finish
before releasing the keys.  This process is best achieved with the receiver
laying face upward on a table top (having 3 hands also helps!)... it is not
designed to require regular adjustment and prevents accidental changing of
values.
17-1 LOCK DETECT - [FUNC] [1] SWITCH ON
This is the length of time provided for the VCO to travel and PLL to “lock” onto
a new frequency.  The shorter the time, the faster the search and scan rate.
However, the shorter the time, the less reliably the process will be.
A compromise has to be made.  If you scan the extremes of the receiver’s
frequency coverage and experience “PLL-ERROR” messages, it may be worth
increasing the value.  The default is set to 05 milliseconds but a value of 20 is
not unreasonable.  The acceptable range is 00 to 49 milliseconds.
To change the value rotate the [DIAL].  Press [ENT] to accept the changes
and return to normal display.  Press [CLEAR] to abort the menu and return to
normal display.
17-2 SQ DETECT - [FUNC] [2] SWITCH ON
This is the length of time provided for the squelch to determine if a signal is
present.  The longer the value the more reliable the operation but search and
scan speed may be reduced.
The default is set to 30 milliseconds.  The acceptable range is 00 - 49 mS.
To change the value rotate the [DIAL].  Press [ENT] to accept the changes
and return to normal display.  Press [CLEAR] to abort the menu and return to
normal display.
17-3 AUDIO WAIT - [FUNC] [3] SWITCH ON
This is the length of time provided for the squelch to determine if valid
modulation is present when using AUDIO scan and search.  The longer the
value the more reliable the operation but search and scan speed may be
reduced. 
						

							AR8000 operating manual
100
The default is set to 0.3 seconds.  The acceptable range is 0.0 to 4.9
seconds.  For solid operation on 900MHz a value of 0.5 may be better.
To change the value rotate the [DIAL].  Press [ENT] to accept the changes
and return to normal display.  Press [CLEAR] to abort the menu and return to
normal display.
17-4 AUDIO LEVEL - [FUNC] [4] SWITCH ON
This is the level of modulation required for the squelch to determine if valid
modulation is present when using AUDIO scan and search.
The default is set to “0A”.  Alternative useful suggestions are 05 - 1A and in
particular 05 and 17.  The acceptable range is 00 - 4F.
To change the value rotate the [DIAL].  Press [ENT] to accept the changes
and return to normal display.  Press [CLEAR] to abort the menu and return to
normal display.
17-5 LEVEL WAIT - [FUNC] [5] SWITCH ON
This is the length of time for the squelch to access if the SIGNAL LEVEL is
above a predetermined value when using LEVEL search and scan.  The
longer the value the more reliable the operation but search and scan speed
may be reduced.
The default is set to 200 milliseconds.  The acceptable range is 000 to 490
milliseconds.
To change the value rotate the [DIAL].  Press [ENT] to accept the changes
and return to normal display.  Press [CLEAR] to abort the menu and return to
normal display.
(18)  Remote control using a computer (RS232C)
The AR8000 is capable of
remote control using a
computer such as an IBM
compatible and control
software.  A small external
interface and lead is required
and optionally available
(interface model CU-8232).
Further information will be
provided with the optional
CU-8232 interface unit.
