Adjusting The Angle And Position; Adjustment Procedure - Sony PSS-650 Manuel D'installation

Adjusting the Angle and
Position
You can adjust the angle of rotation of the projector in
the horizontal plane, the up/down/left/right tilt of the
projector, and the front/back/left/right position of the
projector (see page 22 for details about height
adjustment).
• Adjust the projector, without keystone correction on
the projector, so that the projected image and the edges
of the screen are parallel. Keystone distortion occurs if
the screen and the projector are not directly facing
each other. Adjust the angle while monitoring the
image on the screen until the screen and projector are
directly facing each other.
• While referring to the operating guide for the
projector, first perform an initial adjustment of the size
and focus of the projected image from the projector,
adjust the lens shift, and then adjust the angle and
position of the projector.

Adjustment procedure

1
If the angle and position do not match the screen,
readjust the projector using procedures A) to E).
It is recommended that procedures A) to C) be
performed first to reduce image distortion, and then
perform adjustment using procedures D) and E).
A) B)
D)
Tip
If keystone distortion occurs after adjusting the
angle of the projector, without keystone correction
on the projector, the positions of the screen and
projector may be off center. Check the screen and
projector are directly facing each other. You can
also perform keystone correction on the projector.
2
After all adjustments are completed, tighten all
adjustment retaining bolts.

Note
When loosening bolts, take care not to loosen them
too much such that they fall out. You can make
adjustments by loosening the bolts by one half turn
to one full turn.
A) Adjusting the horizontal rotation
Perform this adjustment if the top and bottom edges of
the projected image are not parallel.
1
Loosen the four M6 bolts (a) securing the
horizontal angle of rotation of the adjustment
bracket, and move the projector left/right to adjust
the projected image until the top and bottom edges
are parallel.
