Maintenance and Cleaning

To help ensure optimized performance and reliability, regularly check electrical, optical and other components
as described below.
DANGER
protective clothing is worn during maintenance.

4.4.1 Lamp

CHECK: Every 60 days or 500 hours
Do the following (always disconnecting from AC first, and wearing authorized protective safety gear):
• Check the contact surfaces of anode (positive) and cathode (negative) connections for cleanliness.
• Clean electrical contact surfaces as necessary to prevent contact resistance from scorching connectors. Use
appropriate contact cleaner.
• Verify that all electrical and lamp connections are tight.

4.4.2 Optical

Unnecessary cleaning of optics can be more harmful than helpful, increasing the risk of degrading delicate
coatings and surfaces. In this projector, check only the lens and lamp reflector. Maintenance of other optical
components requires a qualified service technician. Check these components periodically in a clean, dust-free
environment using a high-intensity light source or flashlight. Clean them only when dust, dirt, oil, fingerprints
or other marks are obvious. Never touch an optical surface with your bare hands. Always wear latex lab gloves.
