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 it regularly. The
estimated duration before replacement is 2 000 hours. However, this may be shortened depending on individual lamp characteristics, usage
conditions, and the installation environment. Therefore, it is strongly recommended that a replacement lamp unit be prepared. If the lamp is not
replaced after 2 000 hours of use, a malfunction will occur and the projector will automatically switch off after approximately ten minutes.

f The 2 000 hour usage period is a rough estimate and is not guaranteed.
