HOW IT WORKS
When the projector is turned on or off a signal is sent to the controller 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.

OPTIONAL CONTROL - CIMA-LINK CONTROLLER DESCRIPTION
DESCRIPTION
The optional Cima-Link Controller (IMC-100C) is a state-of-the art bi-directional communication AC
motor controller designed to control your Cima projection screen and integrate with optional infrared
remote, additional Cima screens, and 3rd party applications. Multiple Cima Below Ceilings can be linked
together on any one span when connected together via the optional Cima-Link RS-232 Serial Package or
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.
REPLACEMENT PARTS & SERVICE
No user-serviceable parts are contained within the unit. Contact your dealer or the factory if you require
part replacement or service.
