Hello. We are currently trying to set up our SoundStation IP 5000 and we have encountered some issues with it. First of all, the status indicating LEDs are not working when the MUTE button is pressed or even when it is supposed to be ringing. We said "supposed to be ringing" because it doesn't ring at all. We are sure a connection is made, but the device remains silent, only the LCD screen turns on. On the manual, it is said that some status icons have to appear when the device is connected, but nothing is shown. The most annoying issue we have found is that when we try to change our ringtone, the device freezes and then resets itself. We don't know if the problems we are having are related with the version of firmware (we are using 4.0.7) we have or with the device itself. How can we be sure that it is not a hardware problem? Thanks for your time.
