Powering Off the Projector

1. Press the "Power/Standby" button to turn off the projector
lamp.
2. After pressing the "Power/Standby" button, you will see a
message "Power off the lamp?" on the on-screen display.
Press the "Power/Standby" button again to confirm.
Otherwise the message will disappear after 5 seconds.
3. "Power/Standby" LED indicator will light solid amber for
about 30 seconds. After the "Power/Standby" indicator
starts flashing, you can turn off the main power switch on
the side of the projector.
If you want to turn on the projector again, you must press
the "Power/Standby" button within 90 seconds of the
indicator flashing.
4. Do not turn on the projector immediately following a power
off procedure.
When the "LAMP" indicator flashs green for about 10 seconds,
you will see a message "Fan Fail" on the on-screen display. Please
contact your local dealer or our service center.
When the "TEMP" indicator lights solid orange, it indicates the
projector has been overheated. You will see a message "Over
Temperature" on the on-screen display. The projector will
automatically shut itself down.
Under normal conditions, the projector can be switched on again
for your presentation. If the problem persists, you should contact
your local dealer or our service center.
