3. Connect with network

Network cable (LAN)

Plug the provided network cable into the network socket on the media player.
Plug the other end of the cable into the network switch
Make sure the selected port on the switch is available and enabled for access by your IT department.
Verify that the connection is working (flashing indicator lights on the port)
The media player should now be identifiable on your network, visible with an IP address (router, DHCP table).

Please make sure you have a constant network connection - the player needs to be online regularly and not blocked by a firewall so that it can be updated with new music content and troubleshooting support can be provided if needed.

Network socket (LAN) music player

These domains need to be whitelisted:

*.heardis.com
*.balena-cloud.com

These ports must be enabled:

443 TCP - Fore remote connection and content updates
123 UDP - For NTP time synchronisation
53 UDP - For DNS name resolution

4. Plug audio cable into player

RCA cabel, 3.5 mm stereo jack

When plugging the audio cable into the headphone port of the music player, you should hear music immediately
If you can't hear music, make sure the volume on the amplifier is at an audible level and that the right input channel at the amplifier is selected
If you still can't hear music, check the output signal by plugging headphones into that port of the music player (also see troubleshooting)
If you hear music via the headphones, then the music player has been installed correctly
If you can't hear music via the headphones, repeat the previous steps or visit the troubleshooting guide
