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.
2. To predict when to replace the lamp, check the lamp cumulative operating hours displayed in lamp1-2 of "STATUS".
3. The unit can damage the projector if it has not been replaced after 2 000 hours of usage.

about 10 minutes.
If replacing A-P.C.Board (assembly), read the ROM data from the old P.C.Board and write it in the new one according to
Note: 2 000 hours is not warranty hours, but guideline for replacement.
