replace the lamp unit regularly.
Please refer to [PROJECTOR SETUP] menu → [STATUS] → [RUNTIME] → [LAMP] about the usage time of lamp
(x page 71).
The estimated duration before replacement is 20 000 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.
