The displayed image may differ depending on the model.
You can choose which speakers to use from among available several speakers. Choose one from the
list of speakers. To use both the TV speakers and the AV receiver speakers simultaneously, set this

to mute the TV speakers.
Using the external speakers only disables the volume button and the mute function. In addition, certain
options will be disabled.
