To play Spotify content on your 851N, please follow these steps:
1. Open your Spotify App and select your desired media.
2. Connect to the Network Player using the Spotify 'speaker' icon.
3. Spotify should begin playing on your 851N.
If you then wish to save a Spotify playlist, album or 'Artist Radio' as a preset on your 851N, this is also possible. Begin playing your chosen playlist, then using the front panel interface select the Presets menu and select [Set Preset].
Finally, select the preset number you wish to save the playlist as and your Spotify playlist should now be available when you select this preset number.
Please Note - When connecting for the first time both the mobile device and 851N will need to be on the same network in order for the 851N to be discoverable within Spotify.
