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. Using a clean lint-free cloth, gently wipe the camera windows in the top corners and the
reflective tape along the top of the screen.
2. Gently wipe the reflective tape along the sides of the screen.
3. Gently wipe the camera windows in the bottom corners and the reflective strip across the
bottom of the screen.
Cleaning the presence detection sensor
The display has a presence detection sensor on its bottom frame (see Presence detection sensor
on page8).
Inspect the sensor regularly for dust and gently wipe it using a clean lint-free cloth if buildup has
occurred.
CAUTION
Do not use compressed air, water, chemical agents or cleaning agents to clean the sensor.
Maintaining ventilation
The display requires proper ventilation. Dust buildup in the ventilation holes compromises cooling
and can lead 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
regularly. You might have to remove the display from the wall.
For more information on removing the display, see Removing and transporting the display on
page58.
CAUTION
Avoid setting up or using the display in an area with excessive levels of dust, humidity or smoke.
