Maintaining the display

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.
For more information about removing the display, see
Removing and transporting the display
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.
Replacing the pens
To prevent damage to the display’s anti-glare coating, replace a pen if its nibs become worn. You can
purchase replacement pens from the Store for SMART Parts (see
smarttech.com/support/parts-store
).
NOTE
For pen part numbers, refer to the service parts diagrams.
