Sony Drive, Park Ridge, New Jersey 07656 Model: MDS501 No. 415 Subject: The unit won't play a Minidisc Symptom: (51) Date: October 13, 1994 The MDS501 won't play a disc due to a defective ATRAC decoder and/or defective Shockproof memory controller IC. Solution: Improved ATRAC decoders and Shock proof Memory Contoller IC's are available. The improved ICs can be identified by the date/lot number information printed on the IC.

Like the "A", the "E" has no special meaning in this code structure, these letters can be found in all different versions of these IC's. For IC101, the ATRAC Decoder IC type CXD2531/AR/BR, the improved
