Troubleshooting

Problem
The instrument does not turn on.
The instrument turns itself off after a
period of inactivity.
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.
The pedals are unreliable or do not
function at all.
When depressing a pedal, the pedal
board flexes and is not firm.
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 firmly attached to the instrument, and
connected to an AC outlet.
Check that the 'Auto Power Off' function is not enabled.
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 CN24 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 effects that contribute
to the overall piano playing experience.
While these additional effects are intended to enhance the realism of
the instrument, it is possible to reduce their prominence, or disable
them altogether using the sound settings.
Check that the pedal cable is firmly 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.
