5. Media Centre
The device supports UPnP and is DLNA-compatible.
This provides the opportunity to stream music from your network. However, this requires you
to have a compatible device in your network that can function as a server. This can be e.g., a
network hard drive or a conventional PC with e.g., Windows 8 via which access to the shared
folder or media sharing is permitted. The folders can then be browsed and played on the Tuner.
Note - Please make sure your computer laptop is on the same Wi-Fi network as the Radio
before you start using this function.
Music streaming
• Once the UPnP/DLNA compatible server is configure to share media files with your radio, you
can start music streaming.

6. Bluetooth playback
Before transmission between your Bluetooth device and the radio is possible, both devices
must be coupled. This process is called "pairing". The Tuner is served as a receiver, to receive
music stream to play on the Tuner.
If you have already paired a Bluetooth device before, this connection will be restored
automatically when both devices are in range and Bluetooth operation has been selected on
the radio. "Pairing" does not have to be repeated. This function may need to be activated in
your Bluetooth device, however.
• Push the Menu button to display the selection menu for the different playback modes.
• Use the up / down button to select the playback mode Bluetooth and push the dial switch.
• Switch your Bluetooth device to which you want to connect the radio on and activate the
pairing mode here. The device scans for Bluetooth devices in the reception range.
• When the radio is found, your bluetooth device shows its name TUN01-L-XXXX (the XXXX is an
identification code for your radio unit).

11. Trouble Shooting
Problem Cause Solutions
Network down • Confirm that a Wi-Fi or Ethernet Wired connected PC can ac-
cess the internet (i.e. can browse the web) using the same net-
work
• Check that a DHCP server is available,or that you have config-
ured a static IP address on the radio.
• Check that you firewall is not blocking any outgoing ports. As a
minimum the radio needs access to UDP and TCP ports 80,443
and 8008, DNS port 53
Router restricts
access to listed MAC

ment list on your access point.
Note: The radio has separate MAC addresses for wired and
wireless networks

• Optimize the distance of the router’s location
• Check

Change encryption method on router.
The radio supports WEP, WPA, WPA2

If your radio can
connect to the
network
• The station is not broadcasting at this time of the day
(remember it may be located in a different time zone).
• The station has too many people trying to attach to the radio
station server and the server capacity is not large enough.
• The station has reached the maximum allowed number of simul-
taneous listeners.
• The link on the radio is out of date. This is updated automati-
cally every day, so the next time you turn on the link will be
recognised.
No Display and no

1. If the Internet Radio keeps re-buffering radio station:
The Internet Radio is streaming the data from the radio station via your broadband
connection, if there is a high error rate on your broadband connection, or the connection is
intermittent, then it will cause the Internet Radio to pause until the connection is
re-established and it has received enough data to start playing again.
If your Internet Radio keeps stopping, please check the DSL modem to ensure that the
Broadband line is not suffering a high error rate or disconnections. If you are experiencing
these problems, you will need to contact your broadband supplier.
2. What is Buffering?
When playing a stream, the Internet Radio/Media player, downloads a small amount of the
stream before it starts playing. This is used to fill in any gaps in the stream that may occur if
the internet or the wireless network is busy.
The Internet Radio streams music data from the PC while you are listening. If a stream gets
blocked or experiences Internet congestion while transferring it may stop/interfere with the
quality of play. If this happens, check your internet connection speed- it must be faster than
the speed of the streams.
3. My Amplifier is working but some stations cannot be played.
The problem may be due to one or more of the followings:
a. The radio station is no longer broadcasting.
b. The radio station has reached the maximum allowed number of simultaneous listeners.
c. The radio station has changed the stream arrangement and the link is no longer valid.
d. The radio station is not broadcasting at the time of the day (not all stations are
broadcasting 24 hours throughout the day).
e. The Internet connection between your Tuner and the radio station server is too slow or
unstable to support the data rate of the broadcast.
