•The projector doesn’t turn on if the lamp cover isn’t attached securely.
•Be sure to reset the lamp operation time whenever you replace the lamp.
•Do not reset the lamp operation time unless you replace the lamp.
Caution:
•The lamp is fragile. If it is broken, be careful not to cut yourself with glass fragments.
•Contact your dealer for a new lamp.
Interval of lamp replacement
When the lamp shutdown notice is issued, the lamp replacement is recommended even if the lamp is lit normally. Decrease in lumines- cence and/or color brightness indicates that the lamp needs to be replaced. When the lamp operation time exceeds the time elapsed until the lamp shutdown notice*1 is issued, the indicator will blink alter- nately green and red while the lamp is lit (while the lamp is not lit, the indicator will blink red only) and the lamp replacement message will appear on the screen for one minute every time the lamp is turned on. When the lamp operation time exceeds the time elapsed until the lamp shutdown warning*2 is issued, the replacement message (LAMP EXCHANGE) will appear on the screen for one minute at fixed inter- vals*4 thereafter.
When the lamp operation time exceeds the time elapsed until the lamp shutdown*3, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset.
