To ensure accurate image projection, it is very important
that the projector is perpendicular to the projection
surface (though in some cases a distorted image may
be desirable). If the projector is not aligned squarely to the
projection surface, key stoning of the image will occur. Key stoning
is identifi ed by an image that is larger on one side than it is on
the other. This can occur when the projector is tilted too far up or
down or side-to-side.
The Tray can be tilted 15 degrees front to back to compensate
for irregularities in the projection surface (i.e. easels or walls). If
the projection surface is perfectly vertical, the enclosed Bubble
Level will aid in properly aligning the projector. After mounting the
projector onto the Tray, attach the magnetized Bubble Level to any
inside corner of the Tray surface. The length of the Bubble Level
should be in the direction of the tilt. If the bubble is not centered
in the tube, loosen the Tray knobs and tilt the Tray accordingly
until bubble is centered. Retighten both knobs (Fig. 6).
If the projection surface is angled such as on an easel, adjust
the Tray to ensure the image is square.
Hint:
Project a grid with
1/4" squares and measure the projected squares. If they are all
close to the same size (check the corners), the image should be
as square.

ADJUSTING ANGLE
The floor stand height is adjustable from 3 feet to
approximately 4 ½ feet. To adjust the height, loosen the
Locking Collar (Fig. 5) on the Lower Stand Assembly and
move the Upper Y-Bracket assembly to the desired height. This is
easier to do without the projector mounted in the Tray. Retighten
the Locking Collar securely.
Please note that upon reaching
the maximum height of the column, a yellow warning label
becomes visible above the locking collar. Do not extend the
upper column beyond this yellow label. The upper column
will become unstable.
