Lamp unit

The lamp unit is a consumable component. Check the lamp usage duration with "[Information] menu" and perform
regular replacement.
If the replacement message is displayed on the screen and the lamp indicators <LAMP 1 REPLACE> to
<LAMP 4 REPLACE> turn on, replace the lamp units.
Type No.
Attention
• Do not replace the lamp unit until it has cooled down sufficiently. (Wait at least 60 minutes after use.) The inside
of the cover is very hot and may cause burns.
■ Notes on the replacement of the lamp unit
• Since the luminous lamp is made of glass, it may burst if dropped or hit with a hard object. Please handle with
care.
• A Phillips screwdriver is necessary when replacing the lamp unit.
• When replacing the lamp unit, be sure to hold it by the handle.
• The lamp contains mercury. When disposing of the used lamp unit, ask your nearest local authorities or dealer
about proper disposal of the unit.
Attention
• Use only specified lamp units.
• The product numbers of accessories and separately sold components are subject to change without notice.
• Replacement 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 installa-
tion 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.
On-screen display
The lamp replacement instructions
notify the replacement time, and the
lamp status notifies which lamp to
replace.
