Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface. Please be sure to turn off the projector and let it cool down completely before cleaning the lens.
• Blow away dust and dirt from the lens lightly with a blower. And wipe off the dirt with a soft cloth. Do not use cleaners that contain organic solvents.
• Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile solvent, such as alcohol, benzene, thinner or insecticide. Using such materials or maintaining prolonged contact with rubber or vinyl materials may result in damage to the projector surface and cabinet material.

Cleaning the projector case
Before you clean the case, turn the projector off using the proper shutdown procedure as described in "Shutting down the projector"  and unplug the power cord.
• Do not use adhesives, lubricants, oils, or alkaline detergents for maintenance of the projector.  They could adhere to the cabinet and damage it, possibly resulting in the projector falling from its mounting and causing an accident or personal injury. 
• To remove dirt or dust, wipe the case with a soft, lint-free cloth.
• To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH detergent. Then wipe the case.

Storing the projector
If you need to store the projector for an extended time, please follow the instructions below:

• Make sure the temperature and humidity of the storage area are within the recommended range for the projector. Please consult your dealer about the range.
• Retract the adjuster feet.
• Remove the battery from the remote control.
• Pack the projector in its original packing or equivalent.
