Standby Mode
This selects what type of standby mode your player will use. In Network Standby mode your player will still be controllable by the StreamMagic app and other network services.
ECO Mode
In ECO mode your player will use less power than in Network Standby mode (< 0.5 Watts) but will need to be switched on either by the front panel or the remote control before it can be seen and controlled by the StreamMagic app and other services.
