Caution
l
Do not use compressed air to clean the sensors or borders.
l
Do not use water or cleaning agents to clean the touch sensors.
l
Do not apply too much pressure when cleaning the display because you can damage the plastic.
To clean the IR transmitters and sensors
1. With a clean lint-free, non-abrasive cloth, gently wipe the plastic between the screen and the frame
around the perimeter of the display’s screen.
2. If dirt still remains, use 50% isopropyl alcohol to clean the protective plastic between the screen and
the frame.
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.

Caution
Avoid setting up or using the display in an area with excessive levels of dust, humidity, or smoke.
Preventing condensation
If the display has been moved from a cold environment to a warmer one (for example, from storage to
the installation site), let the display sit for a few hours to allow it to acclimate to the new temperature.
Failing to do so can cause humidity to build up in the space between the front glass and the LCD.
If condensation appears under the screen after you turn on the display, select an active video source
and leave the display on for 48 hours. If the condensation doesn’t dissipate, contact SMART support if the
display is still under warranty.
If there is enough moisture between the layers to cause the moisture to drip and run, remove power
immediately and contact SMART Support if the display is still under warranty.
