When to replace the lamp unit
The lamp unit is a consumable component. Brightness decreases according to duration of usage, so
periodical replacement of the lamp unit is necessary. The estimated duration before replacement is 3 000
hours for PT-CW331RE / PT-CX301RE and 3 500 hours for PT-CW241RE. 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.
When the projection lamp of the projector reaches its end of life, the warning message appears on the screen.
Replace the lamp with a new one promptly.
