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. 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 temper
-
atures inside the lamp module. These high temperatures can impact
lamp performance and operating life. Routine maintenance to remove
dust and dirt from the screens lowers the lamp operating tempera
-
ture and prolongs lamp life. To maximize lamp life you will need to
clean the screens every 250 hours. Lamp screen maintenance may need to
occur more often than 250 hours depending on your installation/use envi-
ronment.
1 Remove the lamp module. Refer to “Replacing the projection lamp”
on page 27 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.
Using the security lock
The projector has a security lock for use with a cable lock system. Refer to
the information that came with the lock for instructions on how to use it.
