Product: CD5
Subject: Micro Reset Modification
Symptom: Customer complains of CD not working.
Reason: CD micro is not resetting under certain conditions.
Solution: Perform reset modification listed below to display PCB.
1) Remove: R408 (120k), C414 (1uf), R573 (270k), C547 (1uf), D502.
2) Add a jumper wire from the hot side of S416 to hot side of S502. This wire should not be
excessively long, and should lay flat on the board. (See diagrams below)
Note: Latter production units used an improved reset circuit (U404). U404 is located on the
display PCB under the BOSE ® logo. This modification is not needed on these units.
