Stewart Filmscreen Corp B - Manual (Page 16)

The method you use to raise and lower the screen depends on the type of
switch control devices you have selected.
When you lower or retract the screen, it will stop at its preset limit. If an
obstacle (such as a person or furniture) gets in the path of the screen as it
is lowered, you should use the switch control to stop the screen's motion; it
will not automatically stop if it hits an obstacle.
In general, when the screen is not in use, you should store it in the fully
retracted position.
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. If adjustment to
the extension is necessary, carefully follow these instructions.

Caution
Do not operate the motor when any of the following occurs:
‹ The unit emits any smoke, heat, abnormal noise or
unusual odor.
‹ The unit is damaged in some way, such as damage from
a water leak.
If any of these situations occur, call a qualified service person.
Caution
Improper adjustment of the limit switches can cause
irreparable damage to the screen itself, resulting in voiding the
factory warranty.
Warning!
The screen is fully retracted when the batten is flush with the
bottom of the case. Do not attempt adjustments with the
yellow retraction (UP) limit switch that will further retract the

questions.
