When cleaning the interactive whiteboard system:
o
Wipe the exterior of the projector with a lint-free cloth.
o
If necessary, use a soft cloth moistened with a mild detergent to clean the projector
housing.
l
Do not use abrasive cleaners, waxes or solvents.
When cleaning the projector’s mirror:
l
Use a bellows bulb or air blower bulb (commonly found in audio-visual supply stores) to blow
off dust. Never touch the mirror with your bare hands or a brush.
l
If wiping the mirror is unavoidable, wear protective gloves and gather the cleaning cloth into
a ball. Gently run the cleaning cloth across the mirror as you would a feather duster. Don’t
apply any pressure to the lens or mirror.
