Troubleshooting

The tables below summarise issues that may be experienced with the CA97/CA67 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.
The volume of the device connected to the Line
In jacks is too low/too high (distorted).
Pedals

The pedals are unreliable or do not function
at all.
When depressing a pedal, the pedal board

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 CA97/CA67 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.
This is the correct behaviour, and intended to reproduce the undamped
notes (typically the top two octaves) of an acoustic grand piano.
Check the position of the Line In LEVEL knob (located on the jack panel),
and adjust as necessary.
Possible Cause and Solution
Check that the pedal cable is firmly connected to the instrument
(CA67 only).
Check that the pedal support bolt is fully extended.
