ËImproving the Z9000U units
(Program version-up for HTPC (Home Theater PC) compatibility, performance upgrading and lip
synchronization improvement)
The Z9000U units have been improved in the following 3 points. These improvements can be
confirmed by looking at the program versions.
To implement the above improvements from Level-zto Level-c, it is necessary to update the PC
interface board programs, modify the hardware, and change some parameter settings. There is no
need to replace the PC interface board itself. If this board is replaced, however, the background
setting must be additionally readjusted.
To get the Level-zunit compatible with HTPC, just update the programs. To upgrade the Level-
xunit to Level-c, update the programs and make some readjustments. All these are discussed
below.
