Shutting down the projector
1. Press and a confirmation message will appear
prompting you. If you don't respond in a few seconds,
the message will disappear.
2. Press a second time. The power indicator flashes
orange, the projection light source shuts down, and the
fans will continue to run for approximately 2 seconds
to cool down the projector.
3. Once the cooling process finishes, the power indicator
becomes a steady orange and fans stop. Disconnect
the power cord from the power outlet.
To protect the light source, the projector will not respond to any commands during the cooling process.
