10、g 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.

11、 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. R

12、eset 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

13、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 shif

14、ting 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 10s 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 cod

15、e. Then, actual change procedure is as follows : The table below shows the keys to be used.

Subject digit of the Unique ID to be changed +1 The subject digit is 3, 3 digit Unique ID is 08 (hexadecimal : 8), the value +1 is 09 (hexadecimal : 9). (Example2). Subject digit of the Uniqu

18、e ID to be changed 1 The subject digit is 7, 7 digit Unique ID is 13 (hexadecimal : D), the value 1 is 12 (hexadecimal : C). (Example3). Digit subject to change +1 The current digit subject to change is 7, digit subject to change +1 is 8. (Example4). Digit subject to change 1 The current digit subje

19、ct to change is 3, digit subject to change 1 is 2. (Example5). Determination of Unique ID (Writing) 4.Note : When in the Unique ID Write 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

20、microcomputer and re-boot it for confirm- ing the newly written Unique ID is correct. How to view the Unique ID q Boot in normal mode (Not the Write mode) w Insert a CD and set the CD as the source e When reading CD is complete and the media is deter- mined, select “ACD ID” from the unit MENU. After

21、 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- ply. In the special mode,

22、 when reset, the setting must be changed to High. Unless this is done, the mode does not work. Therefore, the setting must be completed as indicated.
