When the projector and speaker or headphones have successfully connected, the device will be labelled as Connected in the Remotes &
Accessories. You can now output the audio from the ATV to the speaker or headphone.
The projector can only transmit audio from ATV via Bluetooth connection. Even when the projector is switched to other input sources, such as HDMI, as ATV is still running
in the background, it will continue to transmit audio from ATV to the connected Bluetooth speaker or headphones.
