Maintenance
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface of it. Wipe the lens surface gently with an air spray or a soft,
dry lint-free cloth.
To remove dirt or stains on the lens, moisten a soft cloth with water and a neutral detergent and wipe the lens surface gently.
Cleaning the Projector Case
To clean the projector case, first unplug the power cable. To remove dirt or dust, wipe the casing with a soft, dry, lint-free cloth. To remove
stubborn dirt or stains, moisten a soft cloth with water and a neutral detergent and then wipe the casing.
Do not use alcohol, benzene, thinners or other chemical detergents as these can cause the casing to be warped or discolored.
* The projector needs little maintenance. You should keep the lens clean because any dirt or stains may appear
on the screen. If any parts need to be replaced, contact your dealer. When cleaning any part of the projector,
always turn the power off and unplug the projector first.
