  Wipe off dirt and dust with a soft, dry cloth.
  •  If the dirt is persistent, soak the cloth with water and wring it thoroughly before wiping. Dry off the projector with 

a dry cloth.

  •  Do not use solvents such as benzene, thinner, rubbing alcohol, household cleaners, or chemical wipes. Using

  Wipe off dirt and dust off the front surface of the lens with a soft, dry, and clean cloth.
  • Do not use a cloth that is fluffy, dusty, or soaked with oil/water.
  • Do not use excessive force when wiping the lens as it is fragile.

  •  Lenses are made of glass. Impacts or excessive force when wiping may scratch its surface. Please handle with 

care.

  •  Never use flammable solvents or air sprays on or around the projector. The temperature within the projector 

may be extremely hot due to the projection lamp operation. An explosion or fire may still occur even after turn-
ing off the projector. Other than flammable air spray, the internal parts may also become damaged due to cold 
air.
