Reason Of Change

Problem : At maximum volume selection DVD audio level is low but other modes ok.
Solution : Compared the audio level of DVD mode with other modes and now all modes
Audio level at maximum volume is same. So firmware updated and Micom is changed.

If Earlier Version is less than 3.10 then use firmware version V0.01 else V3.14.For
detailed description how to change and check the version refer to the Power Point file
attached (KU-17LZ21_Micom_Change_Guide.ppt).
NOTE: Please check the H-DELAY and CSM data as explained in the file for fine
adjustments (only for version V3.14).
