INSTRUCTION BOOK FOR
Multi-Mask Imager
Important Safety
When using your video equipment, basic safety precautions should always be followed, including the following:
1. Read and understand all instructions before using.
2. Position the cord so that it will not be tripped over, pulled,
or contact hot surfaces.
3. If an extension cord is necessary, a cord with a current rating
at least equal to that of the appliance should be used. Cords
rated for less amperage than the appliance may overheat.
Save These Instructions
4. To reduce the risk of electric shock, do not disassemble this
appliance. Contact an authorized service dealer when repair
work is required. Incorrect reassembly can cause electric
shock when the appliance is used subsequently.
5. The use of an accessory attachment not recommended
by the manufacturer may cause a risk of ire, electric shock,
or injury to persons.
Mounting The Frame
Professional mounting techniques should be adhered to. Da-Lite Screen Company cannot be liable for substandard
or faulty installations.
Frame Assembly
Assembly of the screen should be in a clean environment.
1. Connect the four frame pieces by matching the colored
tapes on the ends of the frame pieces. See Figure 1.
2. Secure with the supplied 5/16" setscrews.
Unpacking and Unrolling the Screen
The viewing side of the screen surface is rolled to the inside.
The screen surface is rolled lengthwise.
1. Remove screen from packaging.
2. On a clean loor, unroll the screen surface viewing side up.
3. Allow the paper to unroll between backside of the screen
surface and loor. See Figure 3.
Figure 1
Positioning the Frame on the Wall
1. Without the screen fabric attached, position the
frame on the wall at the location you desired.
2. Make sure the unit is level and plumb. (You may
need to use shims between the brackets and the
wall to achieve vertical plumb.)
3. Mark the position of the bracket holes on the
wall. See Figure 2.
CAUTION: If the screen is not mounted so that
it is level and plumb, horizontal masking may
jam on retraction.
CAUTION:
• Be careful not to touch or scratch the viewing side
of the surface with ingernails and any sharp tools.
• Do not use any tools to fasten the screen surface
to the frame.
• Do not fold or crease the screen.
ATTENTION:
• Prenez soin de ne pas toucher ou rayer la face de
projection de l'écran avec les ongles ou tout autre objet
pointu.
• N'utilisez aucun outil pour attacher la surface de l'écran
au cadre.
• Ne pliez pas ou ne froissez pas l'écran
ATTENTION: Si l'écran n'est pas installé de
sorte qu'il soit droit et plat, le masquage
horizontal risque de se coincer lors de
l'enroulement.

Attaching the Screen Surface to Frame
1. Place the frame over the screen surface.
2. While lifting the frame with one hand, snap the screen surface
onto the frame. Gently allow the screen to stretch onto snaps.
See Figure 4. Attach the snaps on the top corners and top
horizontal irst, lift the frame to a vertical position to inish
attaching the rest of the snaps.

Tensioning the Bottom Masking Panel
Electrical wiring is required for each mask roller motor. The
vertical masking systems have one motor at the frame top.
Horizontal masking systems have one motor at the frame top
and one at the bottom.
A motor requires standard 120V/220V input. All connections are
made to the electrical box on the audience left side of the unit.

Operating The Mask Adjusting The Mask Extension
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.
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 qualiied
service person.
ATTENTION: Ne mettez pas le moteur en marche lorsque :
• L'unité émet de la fumée, un bruit anormal, de la chaleur
ou une odeur inhabituelle.
• L'unité est endommagée d'une quelconque façon (ex.
dommage dû à une fuite d'eau).
• Si l'une de ces situations se produisait, appelez un
technicien qualiié.
CAUTION: Improper adjustment of the limit switches
can cause irreparable damage to a mask itself, resulting
in voiding the factory warranty.
ATTENTION: Un réglage inapproprié des interrupteurs de
in de course peut endommager de manière irréversible le
masque et entraîner l'annulation de la garantie.
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 lush 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.
AVERTISSEMENT! Un masque est complètement rétracté
lorsque la latte est alignée avec le bas du caisson.
N'essayez pas d'efectuer des réglages avec un
interrupteur de in de course d'enroulement (VERS LE
HAUT) qui causera une rétraction additionnelle d'un
masque. Un réglage incorrect de cet interrupteur peut
endommager sérieusement le masque. Veuillez contacter
l'usine si vous avez des questions.

Adjusting The Mask Extension (Continued)
Modifying the Extension of the Mask
1. You can increase the extension of a mask up to 3" past the
factory preset stop, or you can decrease the extension by
approximately 46" from the factory preset stop. Do not
attempt to modify a mask extension beyond these
recommended amounts.
2. The limit switches are accessed through openings located on
the left side of the frame as shown in Figure 8.
3. Horizontal mask units have limit switches at the top and
bottom of the screens, a set for each roller tube.
WARNING! The up limit switch(es) retract the batten
further into the unit. Adjusting it is not advised. Refer to 1,
3 or 5 as appropriated in Figure 8.
AVERTISSEMENT! Le(s) interrupteur(s) de in de course
supérieur(s) rétracte(nt) la latte à l'intérieur de l'unité. Le
réglage n'est pas recommandé. Référez-vous au points 1,
3 ou 5 tel qu'indiqué dans la igure 8.
To Increase a Mask's Fully Extended (Mask Down)
Stop Position:
1. Lower the mask to its current stop position.
2. Locate the down limit switch(es) located on the left side of
the frame. Refer to 2, 4 or 6 as appropriate in Figure 8. Use an
Allen wrench to turn the switch in a counterclockwise
direction. If the power is on, the mask will drop incrementally
as the switch is turned. NOTE: One complete turn of the
switch will make approximately a 1/2" change in the mask's
stop position.

Screen Care And Cleaning
With reasonable care, you expect many years of trouble-free use
of your Da-Lite projection screen.
To Decrease the Screen Extension:
1. Lower the mask until it is extended about halfway down.
2. Locate the down limit switch(es) located on the left side of
the frame. Refer to 2, 4 or 6 as appropriate in Figure 8. Use
an Allen wrench to turn the switch in a clockwise direction.
NOTE: One complete turn of the switch will make
approximately a 1/2" change in the mask's stop position.
3. Activate the mask 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 mask, it will automatically stop at the new position.

We encourage you to keep your screen clean. Avoid getting any
foreign material on the screen. It may not be possible to remove
scratches, paint, ink, etc.

available at oice supply stores.)
• For tougher spots, use a mild solution detergent, water and a
soft cloth. Rub lightly. Blot with a damp sponge to absorb
excess water.
Do not use any other cleaning materials on the screen.
