Cleaning the camera windows and reflective tape
The DViT technology in your interactive flat panel uses four cameras in the corners of the frame and
the reflective material between the screen and the bezels. Excessive dust buildup on the camera
windows or reflective tape can impair touch performance.
These areas should be inspected annually for dust and should be cleaned if any obvious dust buildup
has occurred.
C A U T I ON
l Do not use compressed air to clean the camera windows or borders.
l Do not use water, chemicals or cleaning agents.
l Applying too much pressure when cleaning the tape or cameras can damage the tape and
cause performance issues or errors.
To clean the camera windows and reflective tape
1. With a clean lint-free cloth, gently wipe the camera windows in the top corners and the reflective
tape along the top of your interactive flat panel screen using the cloth.
2. Gently wipe the reflective tape along the sides of your interactive flat panel screen.
3. Gently wipe the camera windows in the bottom corners and the reflective strip across the bottom
of your interactive flat panel screen.
Maintaining ventilation
Your interactive flat panel requires ventilation to enable the cooling fans to function. Dust buildup in
the ventilation holes compromises cooling and leads to product failure.
l Clean accessible ventilation holes monthly with a dry cloth.
l Use a vacuum cleaner with a narrow hose end fitting to clear the back ventilation holes annually.
You might have to remove the interactive flat panel from your wall. For more information on
removing your interactive flat panel see Removing your interactive flat panel on the next page.
C A U T I ON
Avoid setting up or using your interactive flat panel in an area with excessive levels of dust,
humidity or smoke.
