5. 2. 4. Replacement of A-P.C. board
When the replacement of A-P.C.Board (assembly) is needed, back up the memory information such as adjustment
data from the old board to PC with the service soft. Then transfer this data to the new A-P.C.Board.
For more information refer to the SECTION 3 "Adjustment".

5. 3. Replacement of consumable parts
[Attention]
・
Make sure to turn off the power before replacing the consumable parts.
5. 3. 1. When to replace the lamp unit
1. 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 3 000 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.
2. To predict when to replace the lamp, check the lamp cumulative operating hours displayed in lamp1-4 of "STATUS".
3. The unit can damage the projector if it has not been replaced after 3 000 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 3 000 hours, the power will be switch off after
about 10 minutes.
