returns to the MENU, even though the Episode Index is momentarily played
back.

Solution:

• Regarding the above items #1), 2), 3) and 5):
We have corrected the Back-end software so that no malfunction occurs.

• Regarding the item #4):
The disc was such a disc that the image and sound interrupt momentarily when
switching the Layer. However, we improved the Layer's switching processing
software of the Back-end so that the image and sound are not interrupted.

MODIFICATION: Upon customer claim or refurbishment of the unit. Please
record the program files onto blank CD-R Discs individually and separately, and
update the above models upon refurbishment, and your customer's unit upon
claim.

Note:

• When recording the above program files on CD-R Discs, the format shall be
"ISO9660" and the Session shall be "CLOSE".

• When recording the file on the CD-R, please record it at the 4-times speed of
the normal speed. If the 4 times speed was not available, please record it at the
minimum speed that is available on your machine.

• If the file was recorded at a high speed, such as 32 or 48 times speed of the
normal speed, the updating may fail due to the data incorrectly recorded on the
CD-R.

Update Procedure:

Cautions during the updating operation:

• Please do not turn off the Power during the rewriting operation.

• If the FL Display continues indicating "LOADING" during the rewriting operation
without changing into "COMPLETE", wait for more than five minutes after closing
the Disc Tray and turn off the Power of the unit. Then, start the rewriting
operation again from the beginning.

1) Updating the System MICON:

(1) Turn on the Power of the unit, press the "OPEN/CLOSE" button and open the
Disc Tray.
(2) Set the CD-R (Ver.6542-5) for rewriting the System MICON to the Disc Tray
and press the "OPEN/CLOSE" button.

• The Disc Tray closes and the updating is performed automatically.

• After indicating "LOADING" on the FL Display, the Power of the unit turns off
once and turns it on again.

• After "WRITING" appeared on the FL Display, "COMPLETE" appears on the
Display.
