Stewart Filmscreen Corp LCD Front Projector - Manual (Page 16)

14 Stewart Filmscreen Corporation
Each roller tube has a set of limit switches. The extension and retraction
limit switches have been preset at the factory. In general, we advise you to
avoid readjusting these switches.
In some cases, to enable proper alignment of the displayed image on the
screen, you may need to adjust the extension of the screen or the mask. If
adjustment to the extension is necessary, carefully follow these instructions.
Caution
Improper adjustment of the limit switches can cause
irreparable damage to the screen itself, resulting in voiding
the factory warranty.
Warning!
The screen and mask are fully retracted when the battens
are flush with the bottom of the case. Do not attempt
adjustments with the yellow retraction (UP) limit switch that
will further retract the screen. Incorrect adjustment of the
switch will cause severe screen damage. Please consult the
factory if you have any questions.
