Model: ADV-M71, D-M71DVS
Subject: Operation noise during the standby mode when playing back
specific MP3 discs.
Symptom: When playing back MP3 or JPEG file that has been recorded by
means of Windows XP, the operation noise (Track Jump) in the standby mode
during the MP3 folder indication is too high. This occurs when recording the data
on a disc by means of Windows XP. The data is always arranged near the Lead-
out area, and the number of Track jump operations to the Lead-out area is
increased. As a result, the operation noise has become audible.
Solution: The F/E (Front-end) firmware has been improved so that the number
of Track Jumps is optimized. Please upgrade your customer's unit to "AK20 [Dr
V040407A0]" upon claim.
