You will only see this message if your device has a rain fade card installed, which allows the last 45 minutes of content to repeat in a loop until signal is restored. If you are having or have recently had bad weather in the area, this is normal – the last 45 minutes of content played will repeat until the weather clears and the satellite connection is re-established.
If you have not had bad weather, verify that the coaxial cable is connected correctly. If the problem persists, unplug the device from the power outlet, wait 30 seconds, and plug the device back in.
