5. Operating Instructions
The DMT Proscreen offers multiple control methods:
5.1 Inline Switch Control
Locate the inline switch on the power cable or screen housing. It typically has "UP", "DOWN", and "STOP" buttons. Press "UP" to extend the screen, "DOWN" to retract it, and "STOP" to pause movement at any desired position.
5.2 Infrared (IR) Remote Control
Point the IR remote control towards the screen's built-in IR receiver or the external IR receiver (if connected). Use the corresponding buttons to extend, retract, or stop the screen.
5.3 12V Trigger Control
The 12V trigger input allows the screen to automatically extend or retract in sync with a projector or other compatible device. Connect a 12V trigger cable (not included) from your projector's 12V output to the screen's 12V trigger input. When the projector is turned on, the screen will extend; when turned off, it will retract.
5.4 RS232/Central Control
For advanced integration into home automation systems, the screen supports RS232/Central Control. Refer to your central control system's manual and the screen's technical specifications for specific commands and connection details. This feature allows for seamless control within a larger integrated system.
6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your projector screen.
- Cleaning the Screen Surface: The screen surface is matte white. Gently wipe the screen with a soft, damp cloth using mild soap and water if necessary. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the screen material. Allow the screen to air dry completely before retracting.
- Cleaning the Housing: Wipe the screen housing with a soft, dry cloth to remove dust.
- Motor Care: The electric motor is maintenance-free. Do not attempt to lubricate or disassemble it.
- Storage: When not in use for extended periods, ensure the screen is fully retracted into its housing to protect the surface from dust and damage.
