Maintenance
Cleaning the 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, solvents or other harsh
chemicals might scratch the lens.
2 Lightly wipe the cleaning cloth over the lens in a circular motion.
Replacing the projection lamp
The lamp hours used timer in the Service Info menu counts the number of
hours the lamp has been in use. Twenty hours before the lamp life expires,
the message “Change lamp” appears on the screen at startup.
NOTE: You can order new lamp housings from www.infocus.com (in select
areas), your retailer or your dealer. Use only a replacement lamp with the
same type and rating as the original lamp.
