DANGER
EXPLOSION HAZARD! Wear authorized protective clothing whenever the lamp door is open
and when handling the lamp. Never twist or bend the quartz lamp body. Use the correct
wattage lamp supplied by Christie. 3) Ensure those within the vicinity of the projector are also
wearing protective safety clothing. 4) Never attempt to remove the lamp when it is hot. The
lamp is under pressure when hot and may explode, causing personal injury, death, or property
damage. Allow the lamp to cool completely.
When the operational life of the lamp reaches halfway, it is recommended that you rotate it 180° to ensure an
even burn of the lamp, improve lamp performance, and extend the life of the lamp. An alarm window appears
on the TPC after you complete the lamp rotation.
