Troubleshooting

Power
Issue
The instrument does not turn on.
The instrument turns itself off after a
period of inactivity.
Sound
Issue
The instrument is turned on, however
no sound is produced when the keys are
played.
The sound distorts when playing at very
loud volume levels.
Strange sounds or noises are heard when
playing with piano sounds.
Pedals
Issue
The pedals are unreliable or do not
function at all.
When depressing a pedal, the pedal
board fl exes and is not fi rm.
The top 18 notes of the keyboard sustain
for longer than neighbouring notes, even
when the damper pedal is not pressed.
Possible Cause and Solution
Check that the power cable is fi rmly attached to the instrument,
and connected to an AC outlet.
Check that the 'Auto Power Off ' function is not enabled.
Possible Cause and Solution
Check that the MASTER VOLUME slider is not set to the lowest
position.
Check that a pair of headphones (or headphone adaptor plug)
are not connected connected to the PHONES jack.
Check that Local Control is enabled in the MIDI Settings menu.
Check that the MASTER VOLUME slider is set to an appropriate
level, reducing the volume if excessive distortion is heard.
The CA15 digital piano attempts to reproduce the rich variety
of tones created by an acoustic grand piano as accurately as
possible. This includes damper resonances and other subtle
eff ects that contribute to the overall piano playing experience.
While these additional eff ects are intended to enhance the realism
of the instrument, it is possible to reduce their prominence, or
disable them altogether using the sound settings.
Possible Cause and Solution
Check that the pedal cable is fi rmly connected to the
instrument.
Check that the pedal support bolt is fully extended.
This is the correct behaviour, and intended to reproduce the
undamped notes (typically the top two octaves) of an acoustic
grand piano.
