Is the Operation Indicator illuminated in orange?
The projector has been designed so that the Operation Indicator is not
extinguished even when the power has been switched off.
The Operation Indicator will be extinguished when the Power Plug has
been disconnected from the socket.
The fan will not cease operations.
The cool-down process (to allow the projector lamp to cool down; the
operation indicator will blink in orange) will be performed after the
power has been switch off by pressing the [Power] button. The operation
indicator will be illuminated in orange when this has been completed, so
remove the power plug from the socket at this point.
*The amount of time required for the cool-down process will depend on
the external temperature.
