Correction of the Firmware.

 

 

 

 Due to a bug in the firmware the audio can be affected when output 

through an HDMI connection. 
 

 
Solution:  

Please record each program file separately onto a blank CD-R, and 

update the unit.

 
Cautions:  
• When recording the file(s) onto a blank CD-R, the format shall be "ISO9660" 
and the session shall be "CLOSE".  
• When recording the program file on the CD-R, please record it at the 4-times 
speed of the normal speed.  
• When the 4-times speed is not available, please record it at the minimum speed 
that is available.  
• If the file was recorded at a high speed, such as 32 or 48 times speed of the 
normal speed, the upgrading may fail due to the data incorrectly recorded on the 
CD-R.
