Appendix IV. Troubleshooting
Trouble
Possible Reason / Solution
A slight noise is heard when turning the
power on or off.
This is normal and nothing to worry
about.
After turning the power on to the
keyboard there was no sound when the
keys were pressed.
Check the master volume is set to the
correct volume. Check that headphones
or any other equipment are not
plugged into the keyboard as these will
cause the built-in speaker system to cut
off automatically.
Sound is distorted or interrupted and
the keyboard is not working properly.
Use of incorrect power adapter. Use
the power adapter supplied or the
batteries may need replacing.
There is a slight difference in timbre of
some notes.
This is normal and is caused by the
many different voice sampling ranges
of the keyboard.
When using the sustain function some
tones have long sustain and some short
sustain.
This is normal. The best length of
sustain for different tones has been
pre-set.
The master volume or accompaniment
volume is not right.
Check that the master volume and
accompaniment volume are set
correctly.
In SYNC status the auto
accompaniment does not work.
Check to make sure Single Finger or
Fingered mode has been selected and
then play a note from the first 19 keys
on the left hand side of the keyboard.
The pitch of the note is not correct.
Check that the transpose is set to 00.
The keyboard appears to switch itself
off.
This is the power saving feature in
operation. See page 6.
