 zThe product numbers of accessories and separately sold components are subject to change without notice.
 zReplacement of all four lamps simultaneously is recommended to ensure a balance brightness and tint.
■
■ When to replace the lamp unit
The lamp unit is a consumable component. Replace the lamp unit regularly
, as its brightness gradually 
decreases over time. The estimated duration before replacement is 2 000 hours (when [Lamp power] is set to 
standard). However, this may be shortened depending on individual lamp characteristics, usage conditions, 
and the installation environment. Earlier replacement of lamp units is recommended for this reason. 
The duration exceeds 2 200 hours of usage for two lamps, the lamps will be switched to the other two lamps if 
they are available. After switching, if the duration exceeds 2 200 hours of usage for one of the two lamps and 
the lamp fails, only the other lamp will light.
If the power is turned on without replacing the lamps after the duration exceeds 2 200 hours of usage for all 
lamps, the power automatically turns off after approximately ten minutes to prevent the malfunction of the 
projector.
