• The Power indicator remains orange.
This projector is designed so that the Power indicator
remains lit even when after the power has been turned off.
The Power indicator will switch off when the power cable
is disconnected from the electrical outlet.
• The cooling fan does not stop.
After the [Power] button is pressed to turn off the power,
the cool-down period starts.
After this, the Power indicator changes to a steady orange,
and you can then disconnect the power cable from the
electrical outlet.
* The cool-down period lasts about 45 seconds. The actual
time will vary depending on the external air temperature.
