No power (all indicators are off). Press POWER.
                                   Be sure the power cord is plugged in.
                                   Try a different AC outlet.
                                   Check the fuse.

No sound.                          If you are listening to an audio
                                   source other than the tape deck, be 
                                   sure TAPE MON is not lit.  If 
                                   necessary, press TAPE MONITOR so the
                                   indicator goes off.
                                   Check the volume level.

                                   Check the SPEAKER buttons.  If you
                                   connect only one pair of speakers,
                                   press only the corresponding SPEAKER
                                   button.

                                   Check the audio source connections.
                                   Be sure you have selected the 
                                   corrected audio source.

                                   Check the speaker connections.

                                   If the PROTECTION indicator comes on,
                                   a built-in protection circuit has 
                                   turned off the amplifier.  Press POWER
                                   to turn off the receiver.  Then:

                                   - 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.

                                   If there is a TV near the receiver,
                                   turn it off or move the receiver away
                                   from the TV.
