SOLUTION
- The speaker connection is out of phase.
Check that the positive and negative poles have been
correctly connected, both at the back of the Receiver
and at the back of the speaker
- Some of the conductor wires of the speaker cable
are in contact with each other which causes distortion.
- Bass and treble controls are set too high in relation to
speaker specifications, the main volume is set too high.
- CD Player or Receiver is defective and should be
serviced by a qualified technician.

- The Receiver has not found any stations in FM mode;
- The selected station does not broadcast any
information.
- The antenna signal is too weak, please see the section
on adjusting the antenna.
- FM tuner mode is reproduced at a very high sound
quality.
- But if the antenna signal is too weak, you will not hear
any whistling but instead you will hear blackouts or
"tick/blob" sounds.
- You must therefore check if the antenna signal is strong
enough.
