•
If you continue to use the lamp after the replacement period has passed, the
possibility that the lamp may explode increases. When the lamp replacement
message appears, replace the lamp with a new one as soon as possible, even if
it is still working.

Do not repeatedly turn off the power and immediately back on. Turning the
power on and off frequently may shorten the lamp's operating life.
•
Depending on the characteristics of the lamp and the way it has been used,
the lamp may become darker or stop working before the lamp warning
message appears. You should always have a spare lamp unit ready in case it is
needed.
•
We recommend the use of genuine EPSON spare lamps. The use of non-
genuine lamps may affect projection quality and safety. Any damage or
malfunction caused by the use of non-genuine lamps may not covered by
Epson's warranty.
