 (15)  Option - Descrambler (voice inverter)
- DS8000
An optional voice inversion unit may be fitted to the
AR5000 to enable decoding of certain types of analogue
scrambling (such as some cordless phones).  Such a board
is not produced by AOR but the receiver has been
designed to accept the DS8000 - available from dealers
in some countries.
15-1  Descrambler installation
Only the upper case of the AR5000 needs to be removed
when installing the optional DS8000 board.  Switch the
receiver off and unplug the power cord.
1  In order to lift the upper case, 
carefully (with the correct
fitting posi-drive screwdriver) remove the 4 screws from
the top cabinet and the 3 screws from each side panel
(the screws on the side of the unit toward the front are
larger than the rest).  The rear edge of the top cabinet
has a flange and the sides have two unused holes (for
mobile mounting).
2  Locate connector J10 in the middle of the IF printed
circuit board (see illustration) and insert the DS8000
making sure the pins mate correctly.
3  Refit the upper case... you may wish to do this once
you have established that the board is operating correctly!
4  The DS8000 must be REGISTERED in the receiver’s
configuration before it will appear on the OPTION MENU
and be used.  Plug in the power cord and ensure that the
supply is connected and active.

when installing the optional CT5000 board.  Switch the
receiver off and unplug the power cord.
1  In order to lift the upper case, 
carefully (with the correct
fitting posi-drive screwdriver) remove the 4 screws from
the top cabinet and the 3 screws from each side panel
(the screws on the side of the unit toward the front are
larger than the rest).  The rear edge of the top cabinet
has a flange and the sides have two unused holes (for
mobile mounting).
2  Locate connector IC31 on the rear-right hand side of
the printed circuit board (see illustration) and insert the
CT5000 making sure the pins mate correctly.  Ensure that
the board is inserted with the crystal resonator and
electrolytic capacitor facing the right hand edge of the
unit and the surface mount components facing IC27.
3  Refit the upper case... you may wish to do this once
you have established that the board is operating correctly!
4  The CT5000 must be REGISTERED in the receiver’s
configuration before it will appear on the OPTION MENU
and be used.  Plug in the power cord and ensure that the
supply is connected and active.
Assuming that power is connected to the AR5000 and
the power switch is currently OFF, press and hold 
key then power up the receiver by pressing and
releasing the 
 
switch while still holding the 
key.  Now release the  key.  The “CTCSS” tone
squelch will now be added to the OPTION menu as the
first item accessed by pressing 
  (unless the
descrambler option is fitted in which case it will be the
second item in the list).
16-2  Operation of the CT5000 - overview
Of course you first need to find a transmission which is
using CTCSS tones!  Assuming that you have located
such a transmission... there are two ways in which CTCSS
may be used, 
SEARCH and SQUELCH.
SEARCH:  Hunt for the CTCSS tones being used.  The
flashing LCD legend “TONE” indicates that CTCSS
frequency search is in operation.
SQUELCH: Selectively monitor only those transmissions
using specific CTCSS tones.  The 
static legend “TONE”
on the top line of the LCD indicates that CTCSS tone
squelch is in operation.
16-3  CTCSS SEARCH
This facility enables you to automatically search and locate
any signals which carry the particular CTCSS frequency
of your interest.
1  To access the CTCSS menu press 
 .  Use
the 
  
keys to access the CTCSS menu, the
LCD legend “CTCSS” confirms selection.
DE-SCR OFF 
(if DS8000 option is fitted)
CTCSS OFF  
						

							PAGE  68          AR5000 OPERATING MANUAL
Note: When the CTCSS search is active it is not possible
to toggle the frequency display and text display.  If the
optional CT5000 board is not fitted the above procedure
will result in no audio being produced.
16-4  CTCSS SQUELCH
The CTCSS tone squelch facility assumes that you either
know the frequency required or you have already used
the CTCSS SEARCH facility to identify the required tones
for specific transmissions.
When this facility is engaged only the selected CTCSS
modulated signals can be received.  No audio will be
heard from other transmissions even if the radio has
received a strong signal (which does not carry the selected
CTCSS frequency).
1  To access the CTCSS menu press 
 .  Use
the 
  keys to access the CTCSS menu, the
LCD legend “CTCSS” confirms selection.
DE-SCR OFF 
(if DS8000 option is fitted)
CTCSS OFF

3  Pull the PCB towards the front panel and lift it as shown
in the diagram.
4  Locate position MF1 on the I.F. PCB (refer to illustration).
The position is currently unoccupied ready for the optional
500 Hz Collins mechanical filter.  Use a desoldering pump
to remove any excess solder from the respective pin
positions.  Insert the CW filter into the cleared holes of the
PCB and securely solder its pins - don’t overheat the filter!
5  Refit the I.F. PCB making sure that all six screws have
been refitted.
6  Refit the upper case... you may wish to do this once
you have established that the filter is operating correctly!
7  The optional 500 Hz filter must be REGISTERED in
the receiver’s configuration before it will appear on the IF
bandwidth display and be used.  Plug in the power cord
and ensure that the supply is connected and active.
Assuming that power is connected to the AR5000 and
the power switch is currently OFF, press and hold 
key then power up the receiver by pressing and
releasing the 
 
switch while still holding the 
key.  Now release the  key.  The 0.5 kHz (500 Hz)
bandwidth will now be available for use.
17-2  Installation of other filters
Consult your AOR dealer if you wish to install other filters
such as 2.5 kHz and 5.5 kHz.  To add these substitute
filters, the standard ceramic filters must be replaced, this
requires good quality tools and technical skill.  
Use of an
electric desoldering pump and professional grade
soldering iron is highly recommended.
Never try to remove the standard fitted ceramic filters
by force, such an attempt may damage the printed circuit
board (high quality multiple layers) invalidating the
warranty.
Note:  The LCD legends will still display 3.0 kHz and 6.0
kHz even when substitute 2.5 kHz and 5.5 kHz Collins
optional filters have been fitted.
1  In order to lift the upper case, 
carefully (with the correct
fitting posi-drive screwdriver) remove the 4 screws from
the top cabinet and the 3 screws from each side panel
(the screws on the side of the unit toward the front are
larger than the rest).  The rear edge of the top cabinet
has a flange and the sides have two unused holes (for
mobile mounting).
2  On the top-rearmost PCB (I.F. board), disconnect the
IF OUT connector J8 (PCB side) from the socket on the
rear-left of this board and remove the six board fixing
screws.
3  Pull the PCB towards the front panel and lift it as shown
in the diagram.
4  Remove the standard fitted filter:
CF1 2.4 kHz ceramic filter (front panel legend 3.0
kHz) from positionMF2 to fit the 2.5 kHz optional
Collins mechanical filter.
CF3 9.0 kHz ceramic filter (front panel legend 6.0
kHz) from positionMF3 to fit the 5.5 kHz optional
Collins mechanical filter.
Note: CF2 & CF4 cannot be replaced.
5  Locate the pin holes designed to accept the Collins
Mechanical filter, and remove excess solder contents from
the holes by using a desoldering pump.
6  Insert the optional filter into the cleared holes of the
PCB and securely solder its pins - don’t overheat the filter!
7  Locate the unused component pads close to the newly
soldered filter pins (on the underside of the PCB).  Two
ZERO OHM resistors (or wire jump leads) have to be
soldered to form a bridge linking the pads together
(resistors not supplied).
8  Refit the upper case... you may wish to do this once
you have established that the filter is operating correctly!
Nothing further is required.

(18)  Trouble shooting - microprocessor
reset
Should the AR5000 fail to operate correctly, refer to the
following instructions before contacting your AOR dealer
for support.
l Memory / search bank corruption
   18-1, 18-2, 18-3
l Set will not respond
   18-1, 18-2, 18-3
l PLL ERROR displayed
   18-1, 18-2, 18-3
l  
switch does not respond
   18-1, 18-2, 18-3
l No audio output
   18-1, 18-4, 18-2, 18-3
The AR5000 may become inoperative on one or two
specific memory, scan or search banks if the data within
the EEPROM (memory storage) becomes corrupted
(power supply transients, static discharge etc).  If this
happens, erase the affected memory channel or search
bank contents and rewrite the correct data.  Usually this
will clear any minor corruption of this kind.
18-1 Power Off / On
The first thing to try is switching the set off and
disconnecting the power cord for about one minute.
Reconnect the power cord, switch the set on and assess
the results.  If possible check the power lead for output of
12 - 16V d.c.
Press and hold the 
 
key for more than one second
to ensure that automode has been selected, check that
the volume control has been advanced (12 o’clock
position), the squelch is set correctly (if in doubt rotate the
squelch control fully anti-clockwise) and that an appropriate
aerial is connected to the displayed aerial connector “ANT
1” or “ANT 2”.  Ensure that LEVEL squelch, VOICE
squelch, CTCSS squelch etc are not inappropriately set.
Ensure that the DESCRAMBLER, CTCSS and 500 Hz
filter options have not been selected if the boards and
filter have not been fitted.
If you have activated the MUTE connector, ensure that
there is a shorting plug in place.
18-2  CPU reset switch
If switching the set off / on does not help, the next action
should be to reset the receiver using the hidden reset
switch provided.
The reset switch is located behind the torque lever to the
right of the MAIN DIAL.1  Move the lever to the downward position, a black cloth
material covers the slot.  The reset switch is located at
the top of the slot about 10mm behind the front panel.
2  Using a match stick or similar tool, press and release
the reset switch (with the AR5000 switched on and
powered in the normal manner).
3  The back light will extinguish then all LCD characters
will be displayed, the set will then power up and resume
normal operation (if it has not automatically switched on
again press the 
 switch).
This will re-boot the CPU without erasing the search/
memory contents or going back to the default setting.  The
last entered frequency in VFO may be lost.
18-3  CPU soft reset
If the reset switch does not help, it is possible to SOFT
RESET the AR5000 CPU.  This will clear all bank link
information and reset the VFO to default parameters
including frequency display of 128.900 MHz.
