                  No sound - If you are listening to an audio source other
                             than the tape deck, be sure the TAPE MONITOR

                             If the PROTECTION indicator comes on, a built
                             in protection circuit has turned off the

                             receiver.  Then, check the following:

                               - Be sure the speakers are correctly
                                 connected.  Be sure there are no stray
                                 wire strands touching other wire strands
                                 or metal objects.

                               - Be sure the receiver is adequately
                                 ventilated.

                               - Be sure the speakers have an impedance of
                                 8 to 16 ohms.

 Low-pitched humming on AM - Move the power cord away from the AM antenna
                             connection wires.

  Unusual beat sound on AM - Turn off the TV or move the receiver away
                             from the TV.
