Hva betyr feilkoden?
The handset microphone gives either a signal that is too high or no signal at all. The causes are an open circuit in the wire between the handset and the control module, or poor contact in the connectors. The handset does not work, but hands-free still operates.
Mulige årsaker
- Open circuit in the microphone wire running from the handset to the control module
- Poor contact, oxidation or a loose joint in the connectors
Hva du kan gjøre
- 1Check that the handset connector is firmly seated and free from oxidation
- 2If the connectors are in order, use a multimeter to check that the microphone signal wire has no open circuit
- 3If no fault is found in the wire, have a workshop try replacing the handset or the holder
