results in an error.

The S-AIR function
Symptom
S-AIR connection is not
established (sound transmission
is not established), e.g., the
indicator of the S-AIR sub unit
does the following:
• Turns off.
• Flashes.
• Turns red.
No sound is heard from the
S-AIR sub unit.
Remedy
• The communication speed of the USB device is extremely slow. Connect a
USB device that this system can play.
• If the transferring and erasing operations are repeated multiple times, the file
structure within the USB device becomes complex. Follow the procedure in the
operating instructions of the USB device to format the USB device. If the
problem persists, contact your nearest Sony dealer.
• You are using an unsupported USB device. See "Playable USB Devices"
(supplement).
• The USB device was disconnected or the power was turned off during
transferring. The USB device may be broken. Follow the procedure in the
operating instructions of the USB device to format the USB device. If the
problem persists, contact your nearest Sony dealer.
• Check if the USB device is write-protected.
• The USB device was disconnected or the power was turned off during erasing.
Delete the partially-erased file. If this does not fix the problem, the USB device
may be broken. Follow the procedure in the operating instructions of the USB
device to format the USB device. If the problem persists, contact your nearest
Sony dealer.
