control devices, including keypads, dry contact outputs, and low-voltage trigger
outputs. With the optional Cima-Link Controller Packages, your Cima screen can be
controlled by local and remote Infrared, IP ethernet, and computer-based signaling
sources such as those manufactured by Control4, AMX, Crestron, Elan Home
Systems with RS-232-C or RS-485 interfaces.
Caution
To be installed and/or used in accordance with appropriate electrical codes and
regulations.
You will need:
♦ Enough ladders for the personnel supporting the screen during the mounting process
♦ A level
♦ Fasteners appropriate for the surface on which the screen is being mounted (See
instructions for the type of mount for recommendations.)

How it Works
When the projector is turned on or off a signal is sent to the STI-100 within the motor
and will trigger the screen to move up or down.
If there is a sudden change in direction, the motor is paused for 1/2 second before
reversing direction. This is to prevent strain on the motor mechanism, and to prevent
damage to any material controlled by the motor. Relays are automatically
de-energized after 120 seconds of operation to reduce power consumption.
1. Connect the RJ25 cable splitter to the RJ25 jack in the Cima unit.
2. Connect an RJ25 cable to each jack in the splitter.
3. Connect the other end of each RJ25 cable to the jack on the projector and keypad.
Note: The maximum length of the RJ25 cable shall not exceed 50’.

The method you use to raise and lower the screen depends on the type of switch
control device you have selected.
When you lower or retract the screen, it will stop at its preset limit. If an obstacle
(such as a person or furniture) is in the path of the screen as it is lowered, 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 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 occurs, call a qualified service person.
Improper adjustment of the limit switches can cause irreparable damage to the
screen itself, resulting in voiding the factory warranty.
Description
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.
Warning!
The screen is fully retracted when the batten is 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.
Adjusting the Screen Extension
You can increase the extension of the screen up to 3" (7.5 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 (audience left) of the screen roller tube
inside the case, after removing the dust cover.
To increase the screen's fully extended (screen down) stop position:
1. Lower the screen to its current stop position.
2. Remove the dust cover to locate the white extension (down) limit switch on the left
side of the screen tube (audience left). Use a small electrician’s style screwdriver
or a 5/32” (.4 cm) hex wrench to turn the switch in a counterclockwise direction. If the
power is still on, the screen 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's stop position.
1. Lower the screen until it is extended about halfway down.
2. Remove the dust cover to locate the white extension (down) limit switch on the left
side of the screen tube (audience left). Use a small electrician’s style screwdriver or
a 5/32” (.4 cm) hex wrench 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's stop position.
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, it will
automatically stop at the new position.
Note: The yellow "UP" limit switch is to stop the motor in the retracted position. We
advise not adjusting this switch as to avoid possible screen damage should the
switch get mis-adjusted.
It is recommended that you make a note of any changes made to the factory preset.
To correctly adjust the batten setting position and side line length on your Cima
screen, it may be necessary to loosen the existing side line attachment screws. After
the adjustment has been completed, the batten weight will be increased on the
screen while decreasing the side line tension.
This procedure can improve the overall flatness of the screen primarily in the lower
section of the image area. In many instances, the screen's factory deployment
setting has been reduced at the site and therefore this batten adjustment is
necessary.
The objective is to thread the screw into the ferrule just enough to get a very low
amount of side line tension (approximately 3 to 4 turns). The side lines will now have
less tension which is desirable. The result is that more batten weight will be
distributed on the screen once this adjustment is completed. You should see a slight

improvement when finished; however, it will take some time for this adjustment to
fully take effect (stretching screen) thereby eliminating any wrinkles, waves, or
puckers.
Screen Tension Adjustment Procedure
1. Push the ferrule down.
2. Turning the screw counter-clockwise
will lengthen the side line, adding batten
weight / tension to the screen. Turning it
clockwise will shorten the side line and
decrease batten weight / tension on the
screen.
3. Align the bottom screw to the recessed
pocket and release it to move the ferrule
back in place and complete adjustment.
With reasonable care, you may expect many years of dependable 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
Treat your screen surface delicately. 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.
Weekly Maintenance
To maximize the longevity of your Cima screen we recommend the screen be
deployed overnight at least once a week.
If using a 3rd party control system to deploy your Cima screen, you may be able to
program the 3rd party system to automatically deploy your Cima screen once a
week.
