Cleaning the Lens

Follow these steps to clean the projection lens:
1 Apply 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, sol-
vents or other harsh chemicals might scratch the lens.
2 Lightly wipe the cleaning cloth over the lens in a circular
motion.
3 If you don't intend to use the projector immediately, replace
the lens cap.

Cleaning the Lamp Filter Screens

In dirty or dusty environments, the dust filter screens on and
around the lamp module can become clogged, causing high tem-
peratures inside the lamp module. These high temperatures can
cause premature lamp failure. Routine maintenance to remove
dust and dirt from the screens lowers the lamp operating temper-
ature and prolongs lamp life. To maximize lamp life you may
want to clean the screen every 250 hours.
1 Remove the lamp module. Refer to "Replacing the Projection
Lamp" on page 30 for instructions.
2 Examine the dust filter screens on the lamp module and in the
lamp housing area. If necessary, use a vacuum cleaner set on
low power to clean the screens. Be careful not to disturb any
internal components when cleaning the screens.
3 Replace the lamp module.
