Something not working as it should? In many cases what appears to be a malfunction can
be traced to a simple error that can be remedied immediately. Before assuming that your PSR-
730/630 is faulty, please check the following points.
PROBLEM POSSIBLE CAUSE/SOLUTION
The speakers produce a “pop” sound whenever the power is
turned ON or OFF.
This is normal and is no cause for alarm.
The volume is reduced or the sound is distorted.
The registration memory doesn’t work properly.
Recorded song data will not play back properly.
The display goes bland and all panel controls are reset.
No sound when the keyboard is played.
Not all simultaneously-played notes sound.
Auto Accompaniment seems to “skip” when the keyboard is
played.
Auto Accompaniment doesn’t sound when started.
Auto accompaniment won’t function properly. No lower keyboard
sound.
The Harmony function will not turn on.
Certain notes sound at the wrong pitch.
The batteries probably need to be replaced. Either replace all six
batteries, or use an AC power adaptor.
The R1/R2/L voice volume settings could be set too low. Make sure
the voice volumes are set at appropriate levels (pages 14, 111).
The Local Control function could be turned off. Make sure Local
Control is turned on (page 127).
You are probably exceeding the maximum polyphony of the
PSR-730/630. The PSR-730 can play up to 64 notes (32 notes
for PSR-630) at the same time — including split, dual, autoaccompaniment,
song, and multi pad notes. Notes exceeding
this limit will not sound.
The MIDI Clock mode may be set to “on”. Make sure it is turned
“off” (page 128).
Make sure that all accompaniment tracks are turned on, and that
the they are all set to appropriate volume levels.
Make sure you are using fingerings recognized by the selected
fingering mode, and are playing in the Auto Accompaniment
section of the keyboard.
Are you sure you’re playing in the Auto-Accompaniment section
of the keyboard? Make sure that the Auto Accompaniment split
point is set appropriately (page 30).
Are you playing chords that the PSR-730/630 can recognize
(see chord types on page 31~)?
Harmony cannot be turned on when the FULL KEYBOARD
fingering mode is selected or if a percussion kit voice is selected.
Select an appropriate fingering mode or voice.
Make sure that the scale tuning value for those notes is set to “0”
(page 115).
