Cleaning the lens
•
Before cleaning the lens, be sure to turn off the projector and unplug the
power cord to allow the projector to cool down for at least 30 minutes.
•
Use a compressed air tank to remove the dust.
•
Use a special cloth for cleaning lens and gently wipe the lens. Do not touch
the lens with your fingers.
•
Do not use alkaline/acid detergents or volatile solvents such as alcohol for
cleaning lens. If the lens is damaged due to the cleaning process, it is not
covered by the warranty.
Warning:
•
Do not use a spray containing flammable gases to remove dust or dirt from the lens.
This may cause a fire due to excessive heat inside the projector.
•
Do not clean the lens if the projector is warming up as this may cause the lens’ surface
film to peel off.
•
Do not wipe or tap the lens with a hard object.
