If you still can’t control your iPod/iPhone, start
playback by pressing your iPod/iPhone model’s Play
button. Remote operation should then be possible.

Try resetting your iPod/iPhone.
—
Depending on your iPod/iPhone, some buttons may
not work as expected.

a different input source. If playback is not paused,
the Direct Change function may select your
iPod/iPhone as the input source by mistake during

Music Server and Internet Radio
Check the network connection between the AV
receiver and your router or switch.
—
Make sure that your modem and router are properly
connected, and make sure they are both turned on.
—
Make sure the server is up and running and
compatible with the AV receiver.
Check the “Network Setup”.
Make sure your server is compatible with the AV
receiver.
If you download or copy large files on your
computer, playback may be interrupted. Try closing
any unused programs, use a more powerful
computer, or use a dedicated server.
—
If the server is serving large music files to several
networked devices simultaneously, the network may
become overloaded and playback may be
interrupted. Reduce the number of playback devices
on the network, upgrade your network, or use a
switch instead of a hub.
—
If you’re using DHCP, your router may not always
allocate the same IP address to the AV receiver, so if
you find that you can’t connect to a server or Internet
radio station, recheck the AV receiver’s IP address
on “
Network
” screen.
USB Device Playback
Make sure the USB device is plugged in properly.

The AV receiver supports USB devices that support
the USB mass storage device class. However,
playback may not be possible with some USB

storage device class.
