Maintenance
Cleaning the lens
1Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
Avoid using an excessive amount of cleaner, and don’t apply the
cleaner directly to the lens. Abrasive cleaners, solvents or other harsh
chemicals might scratch the lens.
2Lightly wipe the cleaning cloth over the lens in a circular motion. If you
don’t intend to use the projector immediately, replace the lens cap.
Replacing the clock batteries
The projector has a lithium Hitachi Maxell battery (part number CR2032) on
the bottom that is used to power the clock used for networking applications.
Visit our website for complete details on using the networking functionality.

2Wait 45 minutes to allow the projector to cool thoroughly.

ner.
5Install a new battery with the “+” side facing up.
