Cleaning the presence detection sensors
Each interactive flat panel has two presence detection sensors on its frame.The sensors should be
inspected regularly for dust and should be cleaned if any obvious dust buildup has occurred.
CAUTION
Do not use compressed air, water, chemical agents or cleaning agents to clean the sensors.
To clean the presence detection sensors
1. Turn off your room system (see
on page 53), and then
disconnect the power sources for the interactive flat panels.
2. Gently wipe the sensors using a clean lint-free cloth.
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 regularly for dust and should be cleaned if any obvious dust
buildup has occurred.
CAUTION
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
cameras and cause performance issues or errors.
To clean the camera windows and reflective tape
1. Turn off your room system (see
on page 53), and then
disconnect the power sources for the interactive flat panels.
2. Using a clean lint-free cloth, gently wipe the camera windows in the top corners and the
reflective tape along the top of the interactive flat panel screens.
3. Gently wipe the reflective tape along the sides of the interactive flat panel screens.
4. Gently wipe the camera windows in the bottom corners and the reflective strip across the
bottom of the interactive flat panel screens.
