The time which is displayed in [LAMP] is a total time when the real usage time in [NORMAL], [ECO] or [QUIET] is
converted to the runtime in [ECO]. Please note that they are not displayed individually.
The displayed time in [LAMP] =
“Lamp runtime of [NORMAL]” × 2 + “Lamp runtime of [ECO]” + “Lamp runtime of [QUIET]” × 2
The real usage time when the displayed time in [LAMP] is 20 000 hours means,
When [Lamp control] is constantly set to [NORMAL] without switching to other modes = 10 000 hours
When [Lamp control] is constantly set to [ECO] without switching to other modes = 20 000 hours
When [Lamp control] is constantly set to [QUIET] without switching to other modes = 10 000 hours
If you continue to use the lamp unit when the displayed time in [LAMP] has reached 20 000 hours, the lamp
turns off automatically at approximately 10 minutes after turning on the power, as it will cause malfunction of the
projector.
