standby mode or wireless transmission is
deactivated.
The surround amplifier is turned on
automatically (the S-AIR/STANDBY
indicator turns green) when the system is
turned on and wireless transmission is
activated.
For details, see “Troubleshooting”

Preventing transmission
to neighbors (Pairing)
If your neighbors also have S-AIR products
and their IDs are the same as yours, your
neighbors could receive the sound of your
S-AIR main unit. To prevent this, you can
identify your S-AIR products by performing
the pairing operation.
x Before the pairing operation
(example)
The sound transmission is established by the
ID.
x After the pairing operation
(example)
Sound transmission is established between
the surround amplifier and the S-AIR main
unit that performed the pairing operation.
