Important Information

Lamp Replacement

•To replace the lamp, follow all instructions provided on page 50.

•Be sure to replace the lamp when the message “The lamp has reached the end of its usable life. Please replace the lamp.” appears. If you continue to use the lamp after the lamp has reached the end of its usable life, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not touch them as the pieces of glass may cause injury.

If this happens, contact your NEC dealer for lamp replacement.

•Allow a minimum of 30 seconds to elapse after turning off the projector. Then turn off the main power switch, disconnect the power cable and allow 60 minutes to cool the projector before replacing the lamp.
