While the 3D surround functions are active on the BRAVIA XR™ TV, no audio comes out from the TV. When you
want to hear TV audio both from the TV and the BLUETOOTH headphones, deactivate the 3D surround functions.
When using a non-BRAVIA XR TV, make sure that PCM is specified as the digital audio output method on the TV.
For specifying the method, refer to the operating instructions supplied with the TV.
Make sure that the TV and the headphones are turned on.
Disconnect the transmitter from the TV and connect it back to the TV. Be sure to plug the cable all the way into the
port.
Make sure that the volume of the headphones is loud enough.
Pair the transmitter with the headphones all over again.
Depending on the headphones, changing the preference for the quality for music playback via BLUETOOTH
connections is available. In such a case, select the “Priority on Stable Connection” (SBC) preference. For details,
refer to the operating instructions supplied with your headphones.
Make sure that the equalizer function is deactivated on the TV.
Move the transmitter and the headphones away from a device such as a microwave oven and a wireless LAN access
point.
Bring the headphones closer to the transmitter. If there is any obstacle between the transmitter and the headphones,
move it out of the way.
Keep the transmitter away from a device such as a radio or a tuner. Use of the transmitter in the vicinity of such a
device may cause noise in audio from the device.
If there is radio interference with another wireless device (a TV, a soundbar, etc.), change the location of the
transmitter. (For example, move the transmitter from left to right or center.)
