indicator and the POWER indicator to take proper maintenance.
The projector is shut down and the WARNING indicator
is blinking red.
When the temperature inside the projector exceeds the normal
temperature, the projector is automatically shut down to protect
internal components. The POWER indicator is blinking while the
projector is being cooled down. When the projector has cooled
down enough (to its normal operating temperature), it can be
turned on again by pressing the STAND-BY button.
