/Set IF BAND to “Narrow” (ST- SB920 only).

/Preset the stations again if you've moved.

There is severe hum and/or background noise.

/Adjust the position or direction of the aerial.

/Tune to a correct frequency.

/Connect an external aerial for FM broadcasts.

/Move the tuner away from the source of the noise.

/Make sure that you tune to an FM station.

/Select a stronger FM station.

“No preset” appears in the display.

/If the mains lead is disconnected from the wall outlet for more than one month, the memory is erased. Preset stations again.

The station was interrupted by another station / The tuner automatically starts searching stations.
