▶■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. 
The unit can damage the 
projector if it has not been replaced after 2
  000 hours of usage. Thus, the lamp automatically turns off after 
approximately ten minutes.
If the cumulative operating time of all 4 lamp unit bulbs exceeds 2 000 hours, the power will be switch of f after 
about 10 minutes.
