Defocused level in magnetic focus adjustment mode
Optimized uniformity can be obtained by setting the magnetic focus "ALL"
and the "4PA" adjustment levels to the defocused levels. The projector is
designed to automatically defocus the red and blue "ALL" adjustment data.
The defocused level varies with the color temperature and the horizontal
frequency (fH) of the input signal. When the magnetic focus mode is
canceled or the MG FOCUS key is pressed again during the magnetic focus
adjustment, the defocused value listed in the tables on the next page is
automatically added to the "ALL" adjustment level, and the magnetic focus
"ALL" data is defocused. The "4PA" data, however, is not defocused
automatically.
If you give priority to uniformity over spot focus, adjust "4PA" completely,
then subtract the value in the table from the "4PA" adjustment level. If you
give priority to spot focus over uniformity, adjust the magnetic focus
"ALL" completely, then subtract the value in the table, which will be added
to the data with automatic defocusing function, from the "ALL" adjustment
level.
