Troubleshooting
If you experience any trouble with your audio system, then you may nd
it useful to visit the help section on our web site.
As a rst step, the following points should be checked.
Is there power to the audio system?
• Make sure your product is plugged in and connected to the mains - see
page 10.
• Ensure your product is switched on.
Isyouraudiosystemnotreceivingaudio?
• Check the volume level of your product.
• Check your product is in range and that you have connected your
product to your network.
• Ensure the product and the device used for control is connected to the
same network.
• Ensure that WiFi is enabled on your device. Refer to your device’s
documentation for details.
• If your product is not visible within UNDOK, rst try restarting the UNDOK
app on your device. Try reinstalling the UNDOK app and check that
you have the latest version installed.
• If the WiFi connection to the product appears unreliable, try relocating
the audio system or try an Ethernet connection to verify the functioning
of the product.
• Try to eliminate possible interference from other sources e.g. cordless
phone, microwave oven etc.
If you have difculty connecting the audio system to your computer network,
some of these steps may help to resolve the problem:
1. Conrm that a WiFi connected PC can access the Internet (i.e. can
browse the web) using the same network.
2. Check that a DHCP server is available (normally a router function).
Your audio system will by default use DHCP unless you choose to
disable it. This may be congured using the menu items ‘Main Menu'
-> 'System settings' -> 'Network' -> 'Manual settings'. This will ask
rst whether you wish to congure a wired or a wireless connection.
For either wired or wireless you then need to choose 'DHCP enable'
or 'DHCP disable'. If you enable DHCP then the audio system will
negotiate with your router (or DHCP server) and will be provided with
an IP address as well as the other settings needed. If you wish to set
the network conguration manually, refer to paragraph 6.
3. Check that your network’s rewall is not blocking any outgoing ports.
As a minimum, the audio system needs access to UDP and TCP
ports 80 and 123. Port 53 may be required for DNS. Some Internet
radio services may require additional ports to be open. Windows
Media Player 12 will allocate a port number for UPnP media sharing
and will congure Microsoft's Windows built-in rewall appropriately.
Other rewall software may require conguration for UPnP or to allow
particular IP addresses to have trusted access.
4. Check that your access point does not restrict connections to particular
MAC addresses (sometimes called MAC address ltering).
You can view the audio system’s MAC address using the menu items
‘Main Menu' -> 'System settings' -> 'Network' -> 'View settings' -> 'MAC
address'. The MAC address will typically be of the form
00:22:61:xx:xx:xx
5. If you have an encrypted network, check that you have entered the
correct encryption key into the product. Remember that text-format
WPA keys are case sensitive. If your audio system displays 'Network
error' when attempting to connect to an encrypted network, then please
ensure that you enter the correct key for the network. If the problem
persists, then you may need to re-check your network conguration.
