• Don’t shut down the projector while the STATUS 
indicator is blinking after the lamp lights up because 
the lamp’s life may be shortened.
• Don’t turn the projector back on right after shutting it 
down because the lamp’s life may be shortened. 
(Wait about 10 minutes before turning the projector 
back on.)
• Before shutting down the projector, be sure to close 
the menu screen. If you shut down the projector 
without closing the menu, the setting data of the 
menu may not be saved.
• If you shut down the projector while controlling the 
projector using the network function, the application 
software such as ProjectorView may fail. For details, 
see “User Manual of LAN Control Utility” contained 
in the CD-ROM.
