•The volume is at -10dB (The display is 30).
•Loudness (LOUD) is OFF.
•CRSC is OFF, regardless of whether there are switching
functions or not.
• SYSTEM Q is NATURAL (= FLAT).
•BEEP will sound anytime with a short push.
•Auxiliary (AUX) is ON.
•DISPLAY TYPE is TYPE C
•TUNER source display will be as follows
<E type> Upper column = PS/Frequency,
Middle column = Spectrum analyzer,
Lower column = Indicator
<M / K type> Upper column = SNPS,
Middle column = Spectrum analyzer,
Lower column = Indicator
• CD source display will be as shown below.
<E / K type> Upper column = P-TIME,
Middle column = Spectrum analyzer,
Lower column = Blank
•SWPRE is SUB WOOFER ( 2 PREOUT models ).
● RDS automatic measurement
Conventionally, the PS display has been visually checked on
the production line.This will be replaced by a new processing.
The PS data will be received and the PS contents is to be
verified as “RDS_TEST.”When this is verified, the P-CON ter-
minal is forced to go OFF.( In this case, “_” means blank.)
→This will be a dedicated test mode processing.
On the P-CON, when power is turned off once and, then,
turned on again, (Power OFF →ON ) the unit will be re-
started.
● Special display when set toTUNER
When inTUNER mode, if any of the following displays appear,
there is an abnormality with the front end.
•“TNE2P_NG” : The E2PROM is still with the default (un-

1. Introduction
The Unique ID is an identification code allocated to each DXM-
6800 mechanism unit.When written to the mechanism unit,
the ID is stored in the Flash memory area, managed by the
DSP.
During servicing of the unit, if and when the mechanism as-
sembly is replaced, the Unique ID of the old unit should be
written to the new mechanism assembly. At the same time,
after moving the Unique ID, the ID seal must also be moved.
The descriptions herein concern writing Unique ID, using the
functions of the DXM-6800 mechanism.It is possible to easily
re-write the Unique ID of the mechanism, using this function.
* DXM-6800 : X92-5100-00
2. Unique ID
The Unique ID is an identification code allocated to each DXM-
6800 mechanism unit.This ID is consisted of 8-digit hexadeci-
mal numbers.
Example : 9F346D22, 352899AC, etc.
The ID number seal is placed on top of the mechanism cabi-
net.The 8-digit numbers and characters are the Unique ID
assigned to the mechanism.The Unique ID can be confirmed
in the MENU mode.
3. How to write the Unique ID, using the unit
In this section, the procedure for writing the Unique ID with
the unit is explained. Since this procedure is realized by put-
ting the mechanism into a special mode, the unit must first be
reset, immediately before conducting the procedure. At the
same time, the display mode of the unit must be set to P-
Time, prior to shifting into the write mode. Unless set to P-
time, 5 seconds after shifting into the write mode, ID digits
and ID numbers will be stopped from displaying.
3.1. How to shift into the Unique ID writing mode using
the unit
Procedure 1. Set the 63pin of the mechanism microcomputer
(TMP91CU27) to High.
(Connect X32 :IC1 63pin and Back Up 3.3V with
a lead.)
Procedure 2. Reset the mechanism microcomputer and boot
it up again.
(Resetting the mechanism microcomputer and
booting it up again can be achieved by cutting
off ACC and Back Up power supply once and
then re-starting the unit.)
Procedure 3. Insert a CD and use it as a source (i.e. let the
unit start reading the Disc.)
Procedure 4. This completes the start up on Unique ID Write
mode.
After shifting into the Unique ID Write mode, the display will
be as shown in the figure below.
(In the Unique ID Write mode, actually, wis displayed first
and, after pressing FF key once in the Write mode, qis dis-
played.)

The Unique ID indicated in the [minutes] section is the target
Unique ID of the current procedure for writing the ID. The
Unique ID in the [seconds] section indicates the next Unique
ID that is to replace the current Unique ID.The digit numbers
of the Unique ID will be displayed in theTrack Number section
of w.
wUnique ID digit number :
The digit numbers of the Unique ID are numbered 1, 2, 3,....
from the left side of the Unique ID.
The contents indicated byT-xx in the track number section are
the digit number of the Unique ID displayed currently in q.
The first digit is the digit number of the Unique ID, which is
currently worked upon and displayed in the [minute] section of
the time code.The second digit is the next digit number of the
Unique ID, which is indicated in the [seconds] section of the
time code.The values of theT-xx will be changed as the target
of the changed Unique ID is moved in the following manner :
T-12 →T-23 → T-34 →T-45 .....→T-78 →T-81 →...The value
in the higher digit (i.e.“1” of T-12, for example) is the current
target for change in the Unique ID.
After the Unique ID has been changed in all of its digits and as
the writing takes place, the progress condition of writing is
indicated in the wsection.
The display contents are;
T-99 : Unique ID writing in progress.
T-11 : Unique ID Writing complete (success)
T-22 : Unique ID Writing complete (failure)
Procedure 5. Changing Unique ID write contents
Using Track Up/Down Key, Unique ID contents
is changed
(In this unit, CONTROL Key is pushed to the left
or right.)
Using FF/FR Key, Unique ID digit to be worked
upon is changed.
(In this unit, the CONTROL Key is pushed 1 sec-
ond or more to the left or right)
Procedure 6. Final write contents is determined and written to
the mechanism.
Using Pause key, the ID is written. (In this unit,
the center section of the CONTROL Key is to be
pressed.)
Procedure 7. 63pin of the mechanism microcomputer
(TMP91CU27) is set back to Low.
(Connection lead is removed.)
Procedure 8. Reset the mechanism microcomputer, and start
it up.
(Resetting the mechanism microcomputer and
booting it up again can be achieved by cutting
off ACC and Back Up power supply once and
then re-starting the unit.)
Procedure 9. Insert a Compact Disc (CD) and select CD as
the source.This determines the type of media to
be played.Then, select from the MENU of the
unit “ACD Unique ID.”This is done to confirm on
the write content of the Unique ID.
When re-doing the procedure, start from Procedure 1 again.
3.2. How to change the Unique ID write content: Explana-
tion on the Procedures 5-6.
When shifting to the Unique ID Write mode, the display will be
as shown in Figure 1.This is the beginning of writing. At this
point, as has been indicated above, the digit for 10's in the T-
xx is the Unique ID digit which is subject for change and its
contents is shown in the [minutes] section of the time code.
Then, actual change procedure is as follows :
The table below shows the keys to be used.
Track Up key Push the Unique ID contents+1 of
CONTROL Key digit which is currently
to left subject to change.
Track Down Push the Unique ID contents -1 of
key CONTROL Key digit which is currently

(Example5). Determination of Unique ID (Writing)
4. Note :
•When in the Unique IDWrite mode, the written Unique ID is
not displayed.The terminal of the mechanism microcom-
puter must be put back to what it was before (63pin to Low).
Then, reset the microcomputer and re-boot it for confirming
the newly written Unique ID is correct.
How to view the Unique ID
qBoot in normal mode (Not the Write mode)
wInsert a CD and set the CD as the source
eWhen reading CD is complete and the media is deter-
mined, select “ACD ID” from the unit MENU.
•After writing the Unique ID on the current mechanism, trans-
fer the ID number seal from the old mechanism.
•In order to start the special mode (Unique ID Write mode),
the 63pin must be changed to High for mode change.When
doing this, BU3.3V should be connected as the power sup-
