Replacing the Lamp Cartridge
• The lamp that is used as a light source in the projector has a limited service life. The rated service life of the lamp is
about 1500 hours (when used in normal mode only). This could be shortened depending on conditions of use and
other factors.
Note that lamp life will be extended when the projector is often used in Eco mode. (The rated service life of the lamp
means the average value of lamp life for lamps that have been manufactured over a long period, and it is derived from
test conditions at this company.)
• When the life of the lamp is exceeded, the STATUS indicator lights a steady red and the message [Replace the Lamp
Cartridge] is displayed on the screen. When this occurs, it is time to replace the lamp cartridge. Please make the
replacement following the procedure below.
• If the projector is used another 100 hours after the lamp’s service life is reached, the power is set to the standby mode
and no longer turns on.
• Contact a store that sells the U4-237 for a replacement lamp. Indicate you need a U4-150 replacement lamp for the
U4-232/U4-237 (order code 28-061).
CAUTION
• Replacement of the lamp cartridge is performed after switching off the power, waiting for the cooling fan to stop,
disconnecting the power plug from the power outlet, and then leaving the projector for about 60 minutes before
replacement is started. Replacement of the lamp cartridge during operation or immediately after operation stops will
cause burns because of the high temperature.
• Do not remove any screws other than those specified.
• Do not touch the lamp with bare hands. Doing so could shorten the life of the lamp.
• If lamp has reached the end of its usable life, the lamp bulb may shatter. When this happens, an explosive sound can
be heard and pieces of glass may be scattered in the lamp cartridge. Do not touch them as the pieces of glass may
cause injury. If this happens, contact your dealer or the store the projector was purchased.
