CHAPTER 5 TROUBLESHOOTING
2. Manual Shading E. Firm Load
This mode is used to change the color of
the image depending on the user conditions
even if regular automatic shading adjustment
and light adjustment using the service tool
are performed. You should not normally use
this.
There are two methods for updating the
firmware: One is to select and execute
pre-registered firmware, and the other is to
select and execute firmware saved on the
computer. The methods using
pre-registration makes it possible to store all
of the firmware within the same folder and
attach comments to firmware, and is easy to
manage.
