General Help guidelines:
If you have trouble connecting the 851N to your network, these steps may help to
resolve the problem:
• Confirm that a connected computer can access the Internet (i.e. can browse the
web) using the same network.
• Check that a DHCP server is available, or that you have configured a static IP
address on the 851N. You can configure a static IP address on the 851N using
the menu item ‘Settings -> Network Config -> Edit Config’, and then select ‘No’ for
‘Auto (DHCP)’. DHCP is however the recommended method.
• Check that your network’s firewall is not blocking any outgoing ports. As a
minimum, the radio needs access to UDP and TCP ports 80, 5 54, 1755, 5000,
6000 and 7070.
• Check your access point does not restrict connections to a particular MAC
addresses. You can view the radio’s MAC address using the menu item ‘Settings
-> Network Config -> View Config -> MAC address’.
• If you have an encrypted Wi-Fi network, check that you have entered the correct
key or passphrase into the 851N. Remember that text-format keys are case
sensitive. If, when attempting to connect to an encrypted network, your 851N
displays: ‘Wireless error’ followed by a 5-digit number, then please ensure that
you enter the correct passphrase for the network. If the problem persists, then
you may need to consult your network configuration.
If your 851N can connect to the network successfully, but is unable to play
particular Stream Magic stations, it may be due to one of the following causes:
• The station is not broadcasting at this time of the day (remember it may be
located in a different time zone).
• The station has reached the maximum allowed number of simultaneous listeners.
• The station is not broadcasting anymore.
• The link in our database is simply out of date.
• The Internet connection between the server (often located in a different country)
and you is slow.
• Try using a computer to play back the stream via the broadcaster’s web site.
If you can play back the station with a computer, you can use the form at
www.stream-magic.com to notify us so that we can investigate.
If you have problems with UPnP playback always check the following:
• Ensure your chosen UPnP server software is capable of serving the file type you
are trying to access. Some servers do not serve FLAC for instance.
• The 851N can only play non DRM files. Files that have DRM controls cannot
be played by the 851N. Some servers may be able to authorise and de-crypt
Microsoft Playsforsure before then serving the content to the 851N but this
operation is not guaranteed as it is purely a function of the server.
• If attempting to play 24-bit WAV or FLAC content note a wired Ethernet connection
is normally required for reliable operation due to bandwidth considerations.
• Check the 851N is capable of playing back the file type you are trying to access.
WMA, AAC, MP3, Vorbis, FLAC and WAV can currently be played. The 851N does
not support ALAC, WMA Pro, WMA lossless, RAW, AU or other file types not
mentioned.
If you have problems with USB Media playback always check the following:
• Check the 851N is capable of playing back the file type you are trying to access.
WMA, AAC, MP3, Vorbis, FLAC and WAV can currently be played.
• The 851N does not support ALAC, WMA Pro, WMA lossless, RAW, AU or other file
types not mentioned.
• For USB Media the 851N can only play non DRM files. Files that have DRM
controls cannot be played.
• Check that your device does not require more than 1A if it is powered from the
USB socket itself.
• Check your device is formatted in FAT32/NTFS format.
• The way you organise your USB media affects the size of internal database the
851N needs to build dynamically as you browse content. Good practice is to
create folders for Artists within which you should have a sub folders for each
Album which then containing the tracks for that Album. Libraries with thousands
of tracks in one folder will progressively slow down the 851Ns media browsing.
For all servicing, in or out of warranty, please contact your dealer.
