Appendix: Troubleshooting
POSSIBLE CAUSE/SOLUTION PROBLEM
The speakers produce a “pop” sound
whenever the power is turned ON or
OFF.
This is normal and is no cause for alarm.
Turn the power OFF and turn the power ON again. The default setting “Local ON”
is automatically selected.
You are probably exceeding the maximum polyphony of the PSR-520. The PSR-
520 can play up to 32 notes at the same time — including split, dual, auto-accom-
paniment, song memory, and multi pad notes. Notes exceeding this limit will not
sound.
Not all simultaneously-played notes
sound.
Auto accompaniment won’t sound right if you’re using SINGLE FINGER type
fingering when the SINGLE FINGER mode is not selected (page 31).
Are you sure you’re playing in the Auto-Accompaniment section of the keyboard?
Auto accompaniment won’t function
properly. No lower keyboard sound.
Are you playing chords that the PSR-520 can recognize (see chord types on page
32)?
The Local Control function could be turned OFF. Make sure Local Control is
turned ON (page 74).
No sound when the keyboard is played.
Something not working as it should? In many cases what appears to be a malfunc-
tion can be traced to a simple error that can be remedied immediately. Before assum-
ing that your PSR-520 is faulty, please check the following points.
Make sure that the Keyboard Volume, Split Voice Volume, and/or Dual Voice Vol-
ume parameters are set at an appropriate level (pages 67, 15, and 18).
Turn the power OFF and turn the power ON again. The appropriate default vol-
ume setting for the voice is automatically selected.
The selected voice does not sound
when the keyboard is played.
Some sections of some styles do not use the accompaniment rhythm track. Rhythm doesn’t sound when started.
Sustain pedal operation will be reversed if you turn ON the power or plug in the
pedal while pressing the pedal. For normal operation turn OFF the power then
turn it back ON while the pedal is not pressed.
Operation of the sustain pedal is re-
versed.
The cursor is not located at the parameter to be edited. Make sure that the cursor
is located at the parameter to be edited (the parameter should be flashing). The desired parameter cannot be ed-
ited.
Make sure that the accompaniment tracks you want to hear are not muted (page
39), and that the Accomp Volume parameter is turned up to a reasonable level
(page 69).
Turn the power OFF and turn the power ON again. The appropriate default track
setting for the style and the default accompaniment volume is automatically se-
lected.
Accompaniment does not play properly.
Neither of these functions can be turned ON if a percussion kit voice is selected.
Make sure a voice between number 01 and 141 is selected.
The Harmony/Echo effect cannot be turned ON when the FINGERED FULL mode
is in use.
The Harmony/Echo and/or Dual Voice
function will not turn ON.
