Troubleshooting
The tables below summarise issues that may be experienced with the CN39 digital piano, explaining the typical
cause(s), and recommended solution(s).

Power
Issue Possible Cause and Solution Page no.
The instrument does not turn on. Check that the power cable is firmly attached to the instrument, and
connected to an AC outlet. p. 14
The instrument turns itself off after a period of
inactivity. Check that the ‘Auto Power Off’ function is not enabled. p. 81

Sound
Issue Possible Cause and Solution Page no.
The instrument is turned on, however no sound
is produced when the keys are pressed. Check that the MASTER VOLUME slider is not set to the lowest position. p. 16
Check that a pair of headphones (or headphone adaptor plug) are not
connected to the PHONES jacks. p. 16
Check that the ‘Local Control’ setting in the MIDI Settings menu is set to On.

The sound distorts when playing at very loud
volume levels. 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
p. 16
Strange sounds or noises are heard when
playing with piano sounds. The CN39 digital piano attempts to reproduce the rich variety of tones
created by an acoustic grand piano as accurately as possible. This
includes various resonances, 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.
p. 83
The top 18 notes of the keyboard sustain for
longer than neighbouring notes, even when the
damper pedal is not pressed. This is the correct behaviour, and intended to reproduce the undamped
notes (typically the top two octaves) of an acoustic grand piano. –

Pedals
Issue Possible Cause and Solution Page no.
The pedals are unreliable or do not function
at all. Check that the pedal cable is firmly connected to the instrument. p. 134
When depressing a pedal, the pedal board
flexes and is not firm. Check that the pedal support bolt is fully extended. p. 134

Headphones
Issue Possible Cause and Solution Page no.
The headphone volume is too low. If the ‘Nominal Impedance’ specification of the headphones is less
than 100 Ω (ohms), set the ‘Phones Volume’ setting in the Phones
Settings menu to High. p. 112
The headphone output sounds strange. Check that the ‘SHS Mode’ and ‘Phones Type’ settings are set to
‘Normal’. p. 110
