4.2 Cleaning Clean the projector when required. Before cleaning, always unplug the
projector from the power outlet.
Lens Cleaning ➤ To avoid the risk of scratching the lenses, only clean the lenses if absolutely
required. A small amount of dust on the lenses will have very little effect on
picture quality. If the lenses must be cleaned, use a DRY soft cotton cloth.
Rub gently in a circular motion.
Case Cleaning ➤ Clean the case with a soft dampened cloth. Use a mild commercial cleaner.
Do not use liquid or aerosol cleaners.

The lens on the ACON Locator Assembly is very tolerant to dust and
should only be cleaned if ACON performance is affected. Cleaning of the
lens (if required) must be performed with great care. Use a DRY soft cotton
