puter and the TUFL microcomputer do not match, and operations of the unit may be destabilized.

2 When NG is displayed on the first screen (version information, etc.) of Service mode
3 After changing MAIN Assy, JACB Assy or Drive Assy
4 After changing HDD (downloading the EPG Library (program code) to HDD)
[Notes]
When downloading is disabled, at ON time, usually "HDD data is not correct" is displayed on screen and "HDD
ERR" on the FL .
