Interval of lamp replacement
The recommended interval of lamp replacement is about
5000 hours* 1, * 2 of consecutive use. Such interval differs
depending on the operating environment and may be
shorter than 5000 hours* 1, * 2 . Decrease in luminescence
and/or color brightness indicates that the lamp needs
to be replaced. When the lamp operation time exceeds
3750 hours* 1 , the indicator will blink alternately between
green and red (while the lamp is lit; when the lamp is
not lit, the indicator will be 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
has been used for about 4750 hours* 1 , the replacement
message (LAMP EXCHANGE) will appear on the screen
for one minute every 25 hours* 1 thereafter.
When the lamp operation time exceeds 5000 hours* 1 * 2 ,
the projector automatically shuts off and can't be used
until the lamp is replaced and the lamp operation time
is reset.
