outlet or power supply using other voltages or
frequencies than rated. If you want to use a power
supply using other voltage than rated, prepare an
appropriate power cord separately.

electric shock.
• Donotplaceanyobjectsonthepowercordor
do not place the projector near heat sources to
prevent damage to the power cord. If the power
cord should be damaged, contact your dealer for
replacement because it may cause fire or electric
shock.
• Donotmodifyoralterthepowercord.Ifthepower
cord is modified or altered, it may cause fire or
electric shock.

period of time. Otherwise, it may cause fire.
Important:
• WhenStandbyModeoftheEfcientModemenu
in the Installation menu is set to LAN, Speaker Out,
or Monitor Out, the fans rotate at very low speed
during standby after plugging the power cord (with
5 second high speed rotation at the beginning)
and after turning off the lamp. This is to cool down
the projector operating various functions during
standby and is not a malfunction. (When Standby
Mode is set to Low, the fans stop during standby.)
Adjusting the position of the
projected image

screen, use the LENS SHIFT dial.
1. Rotate the LENS SHIFT dial inside the top cover of
the projector to adjust the image position.
