5-3-1. Warnings About Replacing the Lamp
When the usage time of the lamp being used as the light source exceeds the lamp replacement time (approximate), the mes-
sage "Lamp1 OverTime" or "Lamp2 OverTime" is displayed on the projector LCD screen. When this happens, the lamp has
reached its replacement time and you should replace it with a new lamp.
TIP
• T he lamp replacement time (approximate) is 3,000 hours.
• Y ou can check the current amount of lamp usage remaining (approximate) using the following items in the
adjustment menus. (See page 48)
- Amount of lamp usage remaining (approximate): "Information" → " Usage" → "Lamp Remaining"
CAUTION
DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off and then
disconnect the power cable. Allow at least one hour for the lamp to cool before handling.
• Use the specified lamp for safety and performance.
• Do not mount the lamp that you first used mounted in lamp 1 in lamp 2, and do not mount the lamp that you first used
mounted in lamp 2 in lamp 1. If you do, the lamp replacement time (approximate) will not be calculated properly.
• Please purchase the replacement lamp at your dealer/distributor. Specify NP-10LP01 as the model number for the replace-
ment lamp when ordering.
• Replace the air filters at the same time as when you replace the lamp. Specify NP-9AF01 as the model number for the
replacement filter when ordering.
• A replacement lamp and air filter kit is also provided. Specify NP-10LF01 as the model number for the replacement lamp
and filter kit when ordering.
• Do not remove any screws other than as specified.
• The lamp has glass attached for protecting the lamp. Handle with care to avoid accidently breaking it. Furthermore, do not
touch the surface of the glass. This may lead to perform degradation in terms of brightness.
• If you continue using the lamp after the message has been displayed, the lamp may blow. When the lamp blows, it shatters
creating a large sound, and fragments of the lamp become scattered around within the lamp house. If this happens, please
contact your dealer/distributor for a replacement.
• If you replace the lamp while the unit is installed suspended from the ceiling, take care to ensure that no one can enter below
the unit. If the lamp shatters, there is a risk of lamp fragments flying everywhere.
The lamp replacement time is not the guarantee time. The actual replacement time varies depending on the
NOTE
usage environment.
