Lamp Cautions - Runco CL-420 Owner's Operating Manual

This projector uses a pressurized mercury lamp. A loud sound may
Caution
indicate lamp failure. Lamp failure is caused by excessive shock,
improper cooling, surface scratches or deterioration of the lamp due
to usage. The period of time up to failure largely varies depending on
the individual lamp and the condition and the frequency of use. It is
important to note that failure can often result in the bulb cracking.
When the lamp replacement indicator and on-screen display icon are
illuminated or are flashing, replace the lamp with a new one
immediately, even if the lamp appears to be operating normally.
If the lamp breaks, glass particles may spread inside the lamp cage
or gas contained in the lamp may be vented into the room from the
exhaust vent. As the gas in this lamp contains mercury, ventilate the
room well if the lamp breaks and avoid all exposure to the released
gas. In case of exposure to the gas, consult a doctor as soon as
possible.
If the lamp breaks, there is also a possibility that glass particles may
spread inside the projector. If this happens, contact your nearest
Authorized Dealer to remove the damaged lamp and ensure safe
operation.
Do not remove the lamp unit immediately after turning off the
projector. Touching a hot lamp can cause burns or injury. Wait at
least one hour after the disconnecting the power cord to allow the
surface of the lamp unit to fully cool before removing.
