Bluetooth playback
Issue
Can't connect to a Bluetooth-
compatible music player or
mobile phone.
Some functions don't work as
expected.
The message "Not found" is
displayed.
The message "Not Available" is
displayed.
Possible cause
The USB device is not compatible,
or the DRX-730 cannot supply
enough power to the device for it to
function properly.
Possible cause
The dock cable is not connected to
the Yamaha YBA-10 or DRX-730
properly.
The Bluetooth device doesn't
support A2DP or AVRCP.
The Bluetooth device is too far
away from the Yamaha YBA-10.
There's an obstacle between the
Bluetooth device and the Yamaha
YBA-10.
A device close by is transmitting at
2.4 GHz (e.g., a microwave oven or
wireless network device).
Pairing has not been performed.
The Bluetooth functionality on the
Bluetooth device is disabled.
Depending on your Bluetooth
device and its firmware version,
some functions may not work as
expected, and some may not work
at all.
The last Bluetooth device used with
the DRX-730 cannot be found.
You cannot pair the Yamaha
YBA-10 with a new Bluetooth
device while it's already connected
to another device.
Solution
Turn the DRX-730 off and on
again.
Set the DRX-730 to standby,
disconnect the USB storage device,
and then reconnect it.
Select the USB input source, and
then connect the USB device.
Select a different input source and
select USB again.
If the USB storage device came with
its own power adapter, use it to
power the USB storage device while
it's connected to the DRX-730.
If the message still appears, the USB
storage device is probably
incompatible with the DRX-730.
Solution
Check the dock cable connections
and correct as necessary (see
page 51).
Use a Bluetooth device that
supports A2DP or AVRCP.
Make sure the Bluetooth device is
in line of sight of the Yamaha
YBA-10 and within 10 meters
(33 ft.).
Move the Yamaha YBA-10 away
from the device.
Pair the Bluetooth device with the
DRX-730 (see page 51).
Make sure Bluetooth functionality
is enabled on the Bluetooth device.
Use a compatible Bluetooth device.
Make sure the Bluetooth device is
discoverable and within range (see
page 51).
Disconnect the currently
connected device before pairing
with the new device.
