l Do not use cleaning solution or glass cleaner on the screens, because they can deteriorate or
discolor the screens.
l Avoid touching the reflective tape between the screens and the bezel, and ensure that this
strip stays dry. Damage to this strip affects touch interactivity.
To clean the screens
1. Turn off your room system (see Turning off your room system on page 33), and then disconnect
the power sources for the interactive flat panels.
2. Wipe the screens with a lint-free, non-abrasive cloth.
Cleaning the presence detection sensors

Cleaning the camera windows and reflective tape
The DViT technology in the interactive flat panels uses four cameras in the corners of the frames and
the reflective material between the screens 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.
