Image surface adjustment
When the image surface adjustment screws are turned,
the focus on the projection surface can be adjusted by
adjusting the inclinations of top and bottom or left and
right of the image surface.
To enhance the accuracy of the image surface
adjustment, repeat the adjustment several times.
Adjustment of the vertical image surface
1
Loosen the image surface adjustment fixing screw
B by turning it to the left several times.
2
Adjust the focus of the projection lens at the
projected surface near the projector using the
button on the remote control or the projector.
3
Check the projected surface further from the
projector, and confirm if the focus position is in
front of the projected surface or at the far back of
the projected surface.
4
Adjust the position of the image surface to adjust
the focus further from the projector. When the
image surface confirmed in step 3 is in front of the
projected surface, turn the image surface
adjustment screw A to the left. When the image
surface confirmed in step 3 is at the far back of the
projected surface, turn the image surface
adjustment screw A to the right.
5
Adjust the position of the image surface by
repeating steps 2 to 4 so that the focus can be
adjusted in all positions.
6
When the adjustment is finished, turn the image
surface adjustment fixing screw B to the right and
tighten the screw until it is fixed.
