4. Pull up the handle (g), and then pull out the lamp unit (h) by the
handle.
5. Remove the lamp attachment unit.
• Pull the lamp unit out of the projector slowly. If it is pulled out
quickly, the lamp may break, scattering glass fragments.

attachment unit.
6. Load a new lamp unit securely into the projector in the right orien-
tation.
7. Tighten up the screw (c) using a Phillips screwdriver (+) to secure
the lamp cover (d).

Interval of lamp replacement
When the lamp shutdown notice is issued, the lamp replacement is
recommended even if the lamp is lit normally. Decrease in lumines-
cence and/or color brightness indicates that the lamp needs to be
replaced. When the lamp operation time exceeds the time elapsed
until the lamp shutdown notice
*1
is issued, the indicator will blink alter-
nately green and red while the lamp is lit (while the lamp is not lit, the
indicator will blink red only) and the lamp replacement message will
appear on the screen for one minute every time the lamp is turned on.
When the lamp operation time exceeds the time elapsed until the
lamp shutdown warning
*2
is issued, the replacement message (LAMP
EXCHANGE) will appear on the screen for one minute at fixed inter-
vals
*4
thereafter.
When the lamp operation time exceeds the time elapsed
until the lamp shutdown
*3
, the projector automatically
shuts off and can’t be used until the lamp is replaced
and the lamp operation time is reset.
The times above are when LAMP MODE of the INSTALLATION menu
is set to LOW. When it is set to STANDARD, this duration will be short-
ened.
*4
These intervals vary depending on the lamp mode setting.
*5
When LAMP MODE is set to STANDARD, the time elapsed until
the lamp shutdown will be shortened to 2000 hours.
Important:
•
Do not open the lamp cover when the projector is set at a ceiling or
a high place. Lamp fragments may fall from the inside if the lamp
were broken.
Please contact your dealer when you need to replace the lamp
with a new one.
