Attention

When to replace the lamp unit

The lamp unit is a consumable component. Since its brightness gradually decreases over time, it is necessary to replace the

lamp unit regularly.

Time for replacement

When [LAMP POWER] is constantly set to [NORMAL] without switching to other modes = 5 000 hours

When [LAMP POWER] is constantly set to [ECO] without switching to other modes = 7 000 hours

but the lamp may go off before the time above mentioned has elapsed depending on individual lamp characteristics, usage

conditions, and the installation environment. It is recommended that the Replacement lamp unit be prepared earlier.

In order to predict the lamp replacement time, please refer to the lamp runtime displayed in [STATUS] (x page 70) →

[RUNTIME] → [LAMP] → [NORMAL] / [ECO]. It also can be obtained by using the following formula. (The time which is

displayed in [ECO] is the converted usage time when set to [NORMAL].)

Formula for lamp replacement time (rough estimate) = “Lamp runtime of [NORMAL]” + “Lamp runtime of [ECO]” × 5/7

If the time which is obtained by the above equation 5 000 hours has elapsed, the lamp turns off automatically after

approximately 10 minutes, as it will cause malfunction of the projector.

Time which is ob-

tained by the above

Over 5 000 hours

If the power is turned on without replacing the lamp, the

power automatically turns off after approximately ten min-

utes to prevent the malfunction of the projector.

Note

f The time which is obtained by the formula for lamp replacement time “5 000 hours” is a rough guideline, but is not a

guarantee. The lamp runtime differs depending on the setting of "LAMP POWER" menu.
