CE DATA CLK 500msec 500msec 500msec G sensor display items When source is STANDBY, by short-pressing ATT key, the display is switched to analogy meter display, in which verti- cal G and horizontal G are displayed. Special display when all lights are on When all lights are on with the STANDBY source, the fol- lowing displays are made when the keys shown below are pressed. 16 KDC-MP928/PSW9531 /PSW9531Y, XXV-01D TEST MODE Initializing AUDIO-related value setting During STANDBY sourcing, by short-pressing key, AU- DIO setting values are returned to the default values. Flash ROM/Static RAM check 1. When entering the test mode, the manufacture code of the Flash ROM (16M) is read and when it is normal, FROMCHK terminal of the 100pin repeats HiLowHi . If the read- ing is abnormal, “Low” is output. If the manufacture code is normal, by short-pressing key, the connection checks on all terminal is started. If the connections are normal, the FROMCHK terminal stops the HiLowHi repeating and outputs “Hi.” If the reading is abnormal, “Low” is output. 2. With all lights turned on and by long-pressing AM key, the data on the Flash ROM (16M) is initialized. While erasing the data, “Data_Erase. . . .” is displayed. Note : Do not touch any key white this is in progress. When erasing is complete, “Erase_OK!” is displayed. If “Erase_NG!” is displayed, it was not possible to erase the data on the Flash ROM (16M). In this case, long-pressing AM key again. If it is the same, then there is an abnormality with the Flash ROM. 3. Regardless of the state of the test mode, when the power is turned on, the manufacture code on the Static RAM is read and, when, normal, Hi is output by the SRAMCHK terminal. When abnormal, Low is output. Other At Power ON “CODE_OFF”, “CODE_ON” displays will not be made. When sourcing STANDBY, by short-pressing AUTO / TI key, GREEN/RED of the key illumination is switched. When staring up in the test mode, LINE MUTE prohibition time is set to 1 second instead of 10 seconds. While in the test mode, security jig should not be used to write the security code. While in the test mode, serial writing jig should not be used to write the serial number. While in the test mode, even when a DC error is detected, the detection information will not be written to the E2PROM. While in the test mode, even after an elapse of pre-set time, the backup memory items will not be written to the E2PROM. Information Clear mode for Test Mode, backup/installer memory, and CD mechanism error log. In the DC error de- tection information clear mode, DEMO mode operation will not be conducted. Also, in the above mode, the menu of the STANDBY source will not display DEMO ON/OFF switching items. While in the test mode, and at the same time, PM_DET terminal is H, the following will apply to the EJECT key, regardless of whether a disc is in the unit or not. Panel full OPEN/CLOSE is conducted with a short-push. (Protection time: 3 seconds) As far as this item is concerned, eject will be achieved by 1 second long-push on the EJECT key. Clearing backup memory and installer memory data (Clearing E2PROM data) 1. By pressing NEXT key and ATT key simultaneously, re- set and start the unit. This will start the initialization pro- cesses for backup and installer memory data and the error log information of the CD mechanism. 2. When initialization is complete, the following display will be made. Normal completion Abnormal ending 1 backup/installer memory initialization: NG Abnormal ending 2 CD mechanism error log initialization: NG Abnormal ending 3 All initialization: NG 3. While in this mode, even after an elapse of a pre-set time, no backup memory items will be written to the E2PROM. 4. This mode is released by resetting.

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. (Please refer to the instruction manual as for the setting method for P-Time.) 3-1. How to shift into the Unique ID writing mode using the unit Procedure 1. Set the 63pin of the mechanism microcomputer (91CU27UG5UR8) 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, w is displayed first and, after pressing FF key once in the Write mode, q is dis- played.) Figure1Initial display of the Unique ID Write mode Where, q Unique ID The contents of what are indicated by x : xx in the time code is the actual contents of the Unique ID. In sections of minutes : seconds, the Unique ID is indicated in decimal numbers. The table below is the correspondence between the decimal and hexadecimal numbers.

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 the Track Number section of w. w Unique 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 by T-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 the T-xx will be changed as the tar- get of the changed Unique ID is moved in the following man- ner : 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 w section. 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.
