What to do if lens of my projector is dirty?

Gently wipe the lens by using lens cleaning cloth. Do not touch the lens with your hands and fingers.

Note :
1) Switch off the power then unplug the power cable of LED projector from the power outlet before cleaning it.
2) Ensure that the lens cools down before cleaning it.
3) Do not use liquid or aerosol cleaners, benzene, or thinners on your LED projector.
4) Never operate this LED projector immediately after moving it from a cold location.
    When the LED projector is exposed to a drastic change in temperature, moisture may condense on the lens and its other internal parts.
    To prevent this, use the unit for at least  2 hours in the circumstance with an extreme or sudden change in temperature occurs.
