User's Manual

The method you use to raise and lower a mask depends on the type of
switch control device you have selected. When you lower or retract a mask,
it will stop at its preset limit.
Note: The horizontal masking panels move more slowly than the vertical
masking panels. The slower motion allows you to adjust the image area
with greater precision.
The motor is designed to be used for short operations such as positioning
the masks in preparation for viewing. The motor is not designed for
continuous duty. If the motor operates continually for more than a few
minutes, it may automatically shut off to prevent damage from overheating.
If the motor occasionally needs to be run more than normal, for example
during initial setup and positioning, allow time for the motor to cool down.
In general, when a mask 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 a mask. If adjustment to
the extension is necessary, carefully follow these instructions.

OPERATING THE MASK
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 a mask itself, resulting in voiding the
factory warranty.
Warning!
A mask is fully retracted
when the batten is
behind the panel of the
frame. Do not attempt
adjustments with a
retraction (UP) limit
switch that will further
retract a mask. Incorrect
adjustment of that
switch will cause panel
damage. Please consult
the factory if you have
any questions.
