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.

1) Preparation of the CD-R for rewriting.

(1) Create the following folder on your PC and store the supplied program files

for rewriting into the newly created folder.

• The Volume Label of the disc for upgrading shall be "RMC_LDR_DOWN".

Please Note (about recording the Disc):

• When recording the supplied file on the blank CD-R, the format shall be

"ISO9660" and the session shall be "CLOSE".

• When recording the supplied file on the disc, please use the lowest recording

speed that is available on your PC. If the file is recorded at a higher speed, the

rewriting operation may fail due to improperly recorded data on the disc.
