Interval of the lamp replacement
The recommended interval of the lamp replacement
is about 2,000-2,500 hours of consecutive use.
However, the replacement interval may be shorter
than such hours depending on the operating
conditions. Decreases in the luminescence and/or the
color brightness will also indicate that the light
source 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 green and red alternately while the lamp is in
operation (and while the lamp is not in operation, the
indicator will blink red only). In addition, the lamp
replacement message will appear on the screen for
one minute every time the power is turned on. When
the lamp operation time exceeds the time elapsed
until the lamp shutdown warning
*2
is issued, the
replacement message will appear on the screen for
one minute every time the power is turned on. When
the lamp operation time exceeds the time elapsed
until the lamp shutdown
*3
, the projector will
automatically shut off for safety purposes and the
power and lamp indicator will illuminate red. The
projector can’t start operating again until the lamp is
replaced and the operation timer is reset.

The lamp is designed to project the image on the LCD

button to turn off the lamp and wait for two
minutes for the lamp and LCD panels to cool
down. Unplug the power cord from the wall outlet
and wait one hour for the lamp to cool down
completely.

flammable objects inside because it may cause fire
or electric shock. If any objects should fall inside,
unplug and contact your dealer.
