Stealth Trapdoor Electriscreen: Owner’s Manual 11
When you lower or retract the screen, it will stop at its 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 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 the screen in the
fully retracted position.
OPERATING THE SCREEN
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 SCREEN EXTENSION
Caution
Improper adjustment of the limit switches can cause
irreparable damage to the screen itself, resulting in voiding
the factory warranty.
Figure 12: Underside view of
Electriscreen
Access to
Limit Switches
Screen
Trap Door

Electrical Access Plate
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.
Modifying the extension of the screen
You can increase the extension of the screen 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 screen extension
beyond these recommended amounts.
The limit switches are located on the left side of the screen roller tube inside
the case, as shown in Figure 12.
To adjust the screen's fully extended (screen down) stop position:
1.Lower the screen to its current fully extended position.
2.Locate the white extension (DOWN) limit switch located on the left
side of the screen tube. Use a screw driver to turn the switch in the
appropriate direction:
– To decrease the screen extension, turn the switch clockwise.
– To increase the extension, turn the switch counterclockwise.
Note: One complete turn of the switch will make approximately a 1/2" /
1.3 cm change in the screen height.
3.Raise the screen, and then lower it again. It should stop at the new
position.
Once you have made the adjustment, whenever you lower the screen, 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.
Warning!
The screen is fully retracted when the trapdoor closes. Do not
attempt adjustments with the yellow retraction (UP) limit
switch that will further retract the screen into the case.
Incorrect adjustment of the switch will cause severe screen
damage. Please consult the factory if you have any questions.

Stealth Trapdoor Electriscreen: Owner’s Manual 13
With reasonable care, you may 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.
