If the sound from the external audio source is too quiet, increase the outputvolume on the external audio source if possible. If this is not sufficient, setthe input volume (AUX VOL LEVEL) in the system settings to level 2 or level 3.
If the sound from the connected external audio source is too loud or distor-ted, lower the output volume on the external audio source if possible. If thisis not sufficient, set AUX VOL LEVEL to level 2 or level 1.

DAB-FM LINKING FunctionON
If reception of the currently selected DAB station is lost (e.g. no DAB availa-ble), the unit attempts to find the station on the FM frequency band andtune to it.
Automatic station tracking between frequency bands only works if the DABstation and the FM station transmit the same station identifier or the DABsignal indicates a corresponding station on the FM frequency band.
If a corresponding FM station is found, (FM) is displayed next to the stationname. When reception for the corresponding DAB station returns, the unitwill switch back to DAB mode after a short time.
