Cleaning the presence detection sensors
Each interactive flat panel has two presence detection sensors on its frame.The sensors should
be inspected annually for dust and should be cleanedif any obvious dust buildup has occurred.
C A U T I O N
Do not use compressed air, water, chemical agents or cleaningagents to clean thesensors.
To clean the presence detection sensors
Gently wipe thesensors using a clean lint-freecloth.
Cleaning the camera windows and reflective tape
The DViT technology in the interactive flat panels uses four cameras in thecorners of the frames
and the reflective material between thescreens 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
build-uphas occurred.
