RGB Color
This screen verifies that the display unit is receiving the
video (R, G, B and Composite sync) signals properly.
The three primary colors should all be shown without
distortion. The combination of all three should produce
a central white section. If any of the colors are missing,
troubleshoot for the color signal (see page 23-221). If
the picture has lines in it or scrolls horizontally, or
vertically, troubleshoot for a Composite sync problem
(see page 23-223).

Gray Tone
This screen diagnoses problems with contrast. You
should be able to see the changes from bar to bar
across the scale. It is normal for the two bars on either
side to appear the same. If you can't see changes from
bar to bar, replace the navigation unit.
＊０７
Black Raster
This diagnostic screen checks for pixels that may be
stuck on. The entire display must be black. If pixels are
stuck on, replace the navigation unit.

Monitor Adjustment
This allows you to center the navigation display. Use
the joystick to move the picture up/down or left/right. It
is unlikely that you will ever need to adjust the monitor
position. The Default button will reset the display
position to factory specifications.
