Appendix V. Troubleshooting
Problem | Possible Reason / Solution |
---|---|
A faint 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.
Check that fingered chord mode is not selected.
Incorrect key presses in fingered chord mode will not produce any sound.
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 main volume or accompaniment volume is not right.| Check that the main
(master) volume and accompaniment volume are set correctly. Note
that the main volume also affects the accompaniment volume.
In SYNC status the auto accompaniment does not work.| Check to make sure that
Chord 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 switches off unexpectedly| This is not a fault. The keyboard has
a power save function that switches the keyboard off after a period of not
being played. Press the power on
/ off button to switch back on.
