Owner’s Manual
Electrimask Electriscreen

Congratulations on your purchase of the finest optical viewing screen available
anywhere in the world!
Please take a moment to review this manual, it will help ensure you many years
of trouble-free service from your new Stewart Filmscreen product.
About your ElectriMask Electriscreen
Stewart’s ElectriMask system is designed to integrate with the latest multi-format
video projectors, which are capable of variable sizes and aspect ratios for
viewing standard broadcast television and the wide format seen in commercial
theaters. The term aspect ratio refers to the format (width to height) in which
your home cinema sources are produced.
Your screen is equipped with a masking system to achieve different aspect
ratios, for example:
2.35:1 screen with vertical masking
1.78:1 screen with horizontal masking
Figure 1: Vertical and horizontal masking systems
The installation, operation, and care of the ElectriMask Electriscreen is the
same regardless of the masking system used.
Note: This manual refers to “AC” to represent electrical power. Your location
may use 120 V, 220 V or other electrical power. Screen systems are
manufactured using the electrical power type specified for the location. Use
appropriate power sources for your location.

The method you use to raise and lower the screen and mask depends on the
type of switch control devices you have selected.
Use the masking screen as needed to establish the appropriate viewing format.
When you lower or retract the main screen or the mask, they will stop at their
preset limits. 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.
The motor is designed to be used for short operations such as lowering the
screen (or mask) 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 the screen is not in use, you should store it in the fully
retracted position.
12 Stewart Filmscreen Corporation
OPERATING THE SCREEN
Caution
Do not operate the motors 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.

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 mask. If
adjustment to the extension is necessary, carefully follow these instructions.
Modifying the extension of the screen and the mask
You can increase the extension of the screen and mask up to 3" / 7.6 cm past
the factory preset stop, or you can decrease the extension by approximately
4-6" (10-15 cm) from the factory preset stop. Do not attempt to modify the
extension beyond these recommended amounts.
The limit switches for each are located on the left side of the roller tube inside
the case, as shown in Figure 12.
To increase the fully extended (screen down) stop position:
1. Lower the screen or mask to its current stop position.
2. Locate the white extension (down) limit switch on the left side of the
roller tube. Use a screwdriver to turn the switch in a
counterclockwise direction. If the power is still on, the screen or
mask will drop incrementally as the switch is turned.
Note: One complete turn of the switch will make approximately a 3/4"
(2 cm) change in the screen or mask stop position.
To decrease the extension:
1. Lower the screen or mask until it is extended about halfway down.
2. Locate the white extension (down) limit switch on the left side of the
roller tube. Use a screwdriver to turn the switch in a clockwise
direction.
Note: One complete turn of the switch will make approximately a 3/4"
(2 cm) change in the screen or mask stop position.
ElectriMask Electriscreen: Owner’s Manual 13
ADJUSTING THE SCREEN EXTENSION
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.

3. Activate the screen in the down direction until it reaches the newly
reduced stop position. Repeat this procedure until the desired stop
position is reached.
Once you have made the adjustment, whenever you lower the screen or mask,
it will automatically stop at the new position.
Note: It is recommended that you make a note of any changes made to the
factory preset.
With reasonable care, you can expect many years of trouble-free use of your
Stewart projection screen.
We encourage you to keep your screen clean. To protect your screen when it is
not in use, store it in the fully retracted position.
Avoid getting any foreign material on the screen, as cleaning may prove very
difficult. It may not be possible to remove scratches, paint, ink, etc.
General maintenance
The screen surface on your screen is delicate. Special attention to these
instructions should be followed when cleaning.
A draftsman-style brush may be used to lightly whisk away any loose
dirt or dust particles. (This type of brush is usually available at office
supply stores.) Stewart Filmscreen has an optional screen cleaning
kit that contains the proper type of brush. Contact your dealer if you
would like to obtain this cleaning kit.
Particles left on the screen when it is retracted into the case may form
an impression on the screen surface. Periodically wipe the back of
the screen with a clean damp cloth.
For tougher spots, use a solution of mild detergent and water. Rub
lightly using a sponge. Blot with a damp sponge to absorb excess
water. Residual water marks will evaporate within a few minutes. Let
the screen air dry completely before retracting.
Do not use any other cleaning materials on the screen. Contact the factory if
you have questions about removing difficult spots.
Replacement parts and service
No user-serviceable parts are contained within the unit. Contact your dealer or
the factory if you require part replacement or service.
