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.
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.
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.
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.

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.
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.

Attach the wall brackets to the wall using appropriate fasteners
at previously marked locations.
Attach the Side Covers to the frame by sliding the Bolts on the
Side Cover tube into the openings on the top and bottom
brackets. See Figure 7.
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 qualiied
service person.
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 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.

Modifying the Extension of the Mask
You can increase the extension of a mask up to 3" past the factory preset stop, or you can decrease the extension by approximately
46" from the factory preset stop. Do not attempt to modify a mask extension beyond these recommended amounts.
The limit switches are accessed through openings located on the
left side of the frame as shown in Figure 8.
Horizontal mask units have limit switches at the top and bottom
of the screens, a set for each roller tube.

Screen Care And Cleaning
With reasonable care, you expect many years of trouble-free use of your Da-Lite projection screen.
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.
General Maintenance
The screen surface on your Multi-Mask Imager 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 oice 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.
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.
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.
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.
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.
