Power off?

Note:

• When the On start function is “On,” this projector is turned

on automatically by connecting the AC power cord to an

AC outlet (p. 46).

• The running speed of cooling fans is changed according

to the temperature inside the projector.

• Do not put the projector in a case before the projector is

cooled enough.

• If the WARNING indicator blinks or emits a red light, see

“Warning Indicator” on page 51.

• While the POWER indicator is blinking, the lamp is being

cooled down and the projector cannot be turned on. Wait

until the POWER indicator stops blinking to turn on the

projector again.

• The fan rotation will terminate directly if the AC power

cord is unplugged immediately after the projector is turned

off.

• The projector can be turned on after the POWER indicator

turns red. The waiting time to restart will be shortened

when the normal power-off processing for fan cooling is

completed, compared with the time the AC power cord is

immediately unplugged after the power-off.
