Cleaning the lamp housing screens
In dirty or dusty environments, the dust filter screens in the lamp housing
area in the LP250 can become clogged, causing high temperatures and pre-
mature lamp failure (these screens are not present on the LP240). Routine
maintenance to remove dust from the screens lowers the lamp operating
temperature and prolongs lamp life. To maximize lamp life you may want
to clean the screen every 250 hours.
1
Remove the lamp module.
2
Examine the dust filter screens 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 and lamp door.
Using the security lock
The projector has a security lock for use with a PC Guardian Cable Lock
System. See page 38 for ordering information. Refer to the information that
came with the lock for instructions on how to use it.
