Operating The Mask

When you lower or retract a mask, it will stop at its present limit.

If an obstacle (such as a person or furniture) gets in the path of a

mask as it is lowered, you should use the switch control to stop

the mask's motion; it will not automatically stop if it hits an

obstacle.

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.

When a mask is not in use, you should store it in the fully

retracted position.

Side

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.

Adjusting The Mask Extension

CAUTION: Improper adjustment of the limit switches

can cause irreparable damage to a mask itself, resulting

in voiding the factory warranty.

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.

WARNING! A mask is fully retracted when the batten

is flush with the bottom of the case. Do not attempt

adjustments with a retraction (UP) limit switch that will

further retract a mask. Incorrect adjustment of that switch

will cause severe mask damage. Please consult the factory

if you have any questions.
