OPERATING THE SCREEN

DESCRIPTION
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.

ii 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.

SWITCH & TRIGGER WIRING
The 3-button, low-voltage keypad operates with only 3 conductors; common, up & down The “Stop” function shorts both directions internally to common You can use both switching functions simultaneously by simply connecting a splitter to the Cima RJ Input jack The trigger input is only a 2 conductor connection.

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.
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 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 (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.

ADJUSTING THE SCREEN EXTENSION (CONTINUED)

To decrease the screen extension:

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.

ADJUSTING THE SCREEN TENSION

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.

CARING FOR AND CLEANING THE SCREEN

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, you can make a cleaning solution using a water-based detergent and warm water To make the solution, mix one part Simple Green, 409, or other water based industrial cleaner with three parts warm water Moisten a clean cotton cloth or Q-Tip with this solution, moisten the stained area, and gently lift off the stain Never use an aggressive scrubbing action as you could damage the screen surface by removing the optical coating Remoisten the area with clean water and dab dry with a clean sponge or cotton cloth Any residual watermarks will evaporate on their own in a few minutes.

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.
