If the incoming indicator on your Furuno Boating Equipment does not sound: * Check that the cable between the incoming indicator and the Communication unit is correctly connected. * Adjust the incoming indicator volume by pressing S to increase the volume. * In the Web software, go to Settings ? Basic settings ? Incoming indicator (enabled service) and check if Voice (telephone), FAX, ISDN UDI, ISDN RDI (UDI/ RDI FELCOM 500 only) are checked.
