• 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
