Troubleshooting

The tables below summarise issues that may be experienced with the CN34 digital piano, explaining the typical
cause(s), and recommended solution(s).
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 pressed.
The sound distorts when playing at very loud
volume levels.
Strange sounds or noises are heard when
playing with piano sounds.
The top 18 notes of the keyboard sustain for
longer than neighbouring notes, even when
the damper pedal is not pressed.
Pedals
Issue
The pedals are unreliable or do not function
at all.
When depressing a pedal, the pedal board
flexes and is not firm.
108
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.
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 to the PHONES jacks.
Check that the 'Local Control' setting in the MIDI Settings menu is set
to On.
Check that the MASTER VOLUME slider is set to an appropriate level,
reducing the volume if excessive distortion is heard.
If connecting the instrument to an amplifier/mixer using the Line Out
jacks, reduce the value of the 'Line Out Volume' setting in the Basic
Settings menu
The CN34 digital piano attempts to reproduce the rich variety of tones
created by an acoustic grand piano as accurately as possible. This
includes string and damper resonances, key-off noises, and other
subtle characteristics that contribute to the overall piano playing
experience.
While these additional tones are intended to enhance the realism of
the instrument, it is possible to reduce their prominence, or disable the
effects altogether using the settings in the Virtual Technician menu.
This is the correct behaviour, and intended to reproduce the undamped
notes (typically the top two octaves) of an acoustic grand piano.
Possible Cause and Solution
Check that the pedal cable is firmly connected to the instrument.
Check that the pedal support bolt is fully extended.
