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.
Replacement procedure for lamp unit
1. Power off the projector and disconnect the power plug from the power outlet.
And wait at least one hour, and then check if the lamp unit has been cooled down.
2. Loosen the lamp unit cover fixing screw (one screw) until it turns freely, and then open the lamp unit cover in the direction of the arrow.
A.Open a little
B.Slide it in the direction of the arrow, and then pull it out backward to remove.
3. Loosen the lamp case fixing screws (two screws each) until they turns freely, and then hold the lamp case handles, pull out backward.
4. Loosen the lamp unit fixing screws (two screws each) until they turns freely, and then pull out the lamp unit from the projector.

#If the lamp unit or lamp case is not installed properly, remove it and then gently install it again.
Pushing it in forcibly or exerting excessive force may break the connector.
# When you place the new lamp unit, the projector resets the total usage time of the lamp unit automatically.
