Maintenance
▶■Lamp unit
The lamp unit is a consumable component. Check the lamp usage time in [PROJECTOR SETUP] → [STATUS] 
(
 page 74) in the menu and change the lamp periodically.
It is recommended that you request a qualified technician to replace the lamp unit. Consult your dealer .
Consult your dealer to purchase a replacement lamp unit (ET
-LAD60A (1 bulb), ET-LAD60AW (2 bulbs)).
▶■Notes on the replacement of the lamp unit

Please handle with care.
▶zA

 Phillips screwdriver is necessary when replacing the lamp unit.
▶z Make sure you hold the lamp unit by its handles during replacement.

▶■ 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. If the lamp is not replaced 
after 2 000 hours of use, a malfunction will occur and the projector will automatically switch of
f after 
approximately ten minutes.
