Cleaning the screens
Follow these instructions to clean the interactive flat panel screens without damaging their
anti-glare coating or other product components.
CAUTION
l
Do not use permanent or dry-erase markers on the screen. If dry-erase markers are used on
the screen, remove the ink as soon as possible with a lint-free, non-abrasive cloth.
l
Do not rub the screen with a dense or rough material.
l
Do not apply pressure to the screen.
l
Do not use cleaning solution or glass cleaner on the interactive flat panel screen, because
they can deteriorate or discolor the screen.
l
Avoid touching the reflective tape between the screen and the bezel, and ensure that this
strip stays dry. Damage to this strip affects touch interactivity.
To clean a screen
1. Shut off the room computer, and then disconnect the power sources for the room computer
and the interactive flat panel.
2. Wipe the screen with a lint-free, non-abrasive cloth.
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
Gently wipe the sensors using a clean lint-free cloth.
Cleaning the DViT camera windows and reflective tape
The DViT technology in each 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 DViT
camera windows or reflective tape can impair touch performance.
