Any idea what the actual purpose of this menu selection is? The fact

quiet regarding the use of this option. Any thoughts?


I believe it measures the CRT cathode current for each gun and adjusts
them to the correct preset levels. It's similar to the AKB used in
TVs, only it doesn't operate continuously. My only question is why
the CRTs in these monitors get so much brighter with age.

The monitors made before they added the restore feature required
either a DAS calibration, or a modification to reduce the G2 voltage.
There are also a lot of 21" Sony monitors with a restore feature that
doesn't work.

I'd like to try and find out more information as to how this feature should
be PROPERLY used. If you know of any good sources of info, please send me
in the right direction. I'll continue to Google on it.

Thanks again.
