You can also connect the projector to Bluetooth audio devices, such as speakers or headphones, to
output the projector's audio from these devices. Select Remotes & Accessories > Pair accessory to
perform pairing.
You may not be able to connect depending on the standard and type of device.
Even when connecting within the specified communication distance, connections can be lost due to
the status of the signal.
The communication method for Bluetooth uses the same frequency (2.4 GHz) as wireless LAN
(IEEE802.11b/g) or microwave ovens. Therefore, if these devices are used at the same time, radio
wave interference may occur, the audio may be interrupted, or communication may not be possible. If
you do need to use these devices at the same time, make sure there is enough distance between
them and the Bluetooth device.
Bluetooth audio devices are not supported in some countries and regions.
