LEDs
The Alarm LED on top of the projector (Figure 11 on page 18) will
alert you to certain problems.
• A solid red Alarm LED means it is time to change the lamp.
See page 31.
• A blinking red Alarm LED means the projector is overheat-
ing. Turn off the projector and allow it to cool.
The other LED on top of the projector indicates the normal oper-
ating state of the projector.
• A solid green LED means the projector is on.
• A blinking green LED means the projector is in DPMS
mode. See page 25.
• An blinking orange LED means the projector is going into
standby mode; a solid orange LED means the projector is in
standby mode. See page 14 for detail on standby mode.

• Make sure that the power cord is properly connected to a func-
tional AC electrical outlet. Make sure that the power cord is
also properly connected to the projector.
