To

The
screen displays three colored squares-light green, brown, and red-
against a cyan background. These four colors are Color Set 0. If they
are correct, press Y and then

The same pattern appears again; this time the squares are cyan, white,

the test.
If any colors display incorrectly, first check the adjustment of your
monitor, and make sure that both ends of the cable are plugged in
firmly. If a problem still exists, press

to display the error
message.
