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

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

is issued, the replacement message (LAMP

EXCHANGE) will appear on the screen for one minute at fixed inter-

vals

thereafter.

When the lamp operation time exceeds the time elapsed

until the lamp shutdown

, the projector automatically

shuts off and can’t be used until the lamp is replaced and

the lamp operation time is reset.

The times above are when LAMP MODE of the INSTALLATION menu

is set to LOW. When it is set to STANDARD, this duration will be short-

ened.

These intervals vary depending on the lamp mode setting.

When LAMP MODE is set to STANDARD, the time elapsed until

the lamp shutdown will be shortened to 2000 hours.

lamp or the projector with the lamp may be regulated due to envi-

ronmental considerations. For disposal or recycling information,
