1、CHANGES IN COURSE OF PRODUCTION*In course of production the 3 disc changer module 3CDC-LC has been introduced as an alternative.Compared to the original used 3CDC-LC-MB there are different servo / motor driver ICs (TDA7073A) used on the CD board.The new board can be identified by the 12 fig. number

2、3103 303 34255 printed in the copper pattern.Note: New chapter 3CDC-LC is enclosed to this Service Information.*From production week 0148 to 0152 a different changer module 3CDC99-DS has been used.This module can be identified by:- The tray is not locked and can be opened by simply pulling it out.-

3、The 12 fig. number printed on the 3CDC99-DS board reads 3103 303 34283.To enable the use of this 3CDC99-DS version following modifications have been implemented:Mechanical:Pos. 107 changed to 8203 306 84031 Cover Tray 3CDC99Front Board:7401 changed to 8203 239 35241 TMP87CP71FNote: This microprocess
