loud volume levels.
Check that the MASTER VOLUME slider is set to an appropriate level,
reducing the volume if excessive distortion is heard. p. 16
Strange sounds or noises are heard when
playing with piano sounds.
The CA98/CA78 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.
The noise occurs when the damper pedal is depressed and released.

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. –
The volume of the device connected to the
Line In jacks is too low/too high (distorted).
Check the position of the Line In LEVEL knob (located on the jack panel),
and adjust as necessary. p. 155
