Caution items

1. When H-key (vertical pin keystone distortion) is adjusted, the vertical position changes, and V-POS (vertical position)

must be adjusted.

However, when the vertical position is raised too much, the on-screen display no longer can be seen.

2. The item

in the contents for service adjustment mode is for adjustment at the plant.

Stay away from this item, as it means adjustment of all items.

3. After entering service adjustment mode, perform adjustment after making notes of the values for each item. The

written values (data) differ according to the set. Using the noted values as a reference facilitates the adjustment.

for theexplanations.

Adjust with the remote control buttons [VOL +/-] so that
the number of horizontal lines of the crosshatch pattern
becomes S.S lines at the top and at the bottom.

Adjust with the remote control buttons [VOL +/-] so that
the interval between the lines of the upper half and the
lower half of the crosshatch pattern becomes uniform.

Adjust with the remote control buttons [VOL +/-] so that
the grid size of the crosshatch pattern becomes the same
at the center and at the top and the bottom.

Adjust with the remote control buttons [VOL +/-] so that
the vertical center of the crosshatch pattern comes to the
center of the screen.

The vertical position changes when [V-POS] is

adjusted. Confirm [H-KEY] and adjust if required.

Adjust with the remote control buttons [VOL +/-] so that
the number of vertical lines of the crosshatch pattern on
the left and on the right becomes 7.2 lines each.
