FM radio troubleshooting

Context
FM radio problems can fall into two categories; not possible to tune into a station when headset cable is
inserted, or it can tune in on a station (Station ID and valid signal strength indicated in display) but there is
no audio. In the latter case please refer to "IHF speaker troubleshooting" or "Headset speaker
troubleshooting" for trouble shooting the downlink audio path and headset detection function. It is assumed
that live FM stations with sufficient signal strength are available on the point of service, and that a dedicated
FM signal generator is not used during troubleshooting.
