Possible Cause and Solution
Check that the power cable is firmly attached to the instrument, and
connected to an AC outlet.
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 CA93/CA63 digital piano attempts to reproduce the rich variety
of tones created by an acoustic grand piano as accurately as possible.
This includes string resonances and damper 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 functions in the Virtual Technician menu.
Check the technical specifications of the headphones.
If the 'Nominal Impedance' specification of the headphones is less
than 100 Ω (ohms), please set the 'Phones Volume' setting in the 'Basic
Settings' menu to 'High'.
Check that the pedal cable is firmly connected to the instrument (CA63).
Check that the pedal support bolt is fully extended.
Check that the USB memory device is formatted to use the FAT/FAT32
filesystem, and not set to 'Write Protect' mode.
Disconnect the USB memory device, turn the instrument off then on,
then reconnect the USB memory device. If the USB memory device
still does not function, it may be damaged or incompatible. Please try
using a different USB memory device.
This is recognised behaviour when using very large capacity (e.g. 8GB+)
USB memory devices.
Check that the audio player volume is not set to 0.
Check that the format of the audio file is supported and listed in the
'Audio Player supported format specifications' table.
Check that the format of the audio file is supported and listed in the
'Audio Player supported format specifications' table.
The file transfer speed of the USB memory device may be too slow to
play the audio file. Please try using a different USB memory device,
ensuring that it conforms to USB2.0 Hi-Speed standards.
The CA93/CA63 digital piano does not contain the full General MIDI
sound bank selection. Consequently, some SMF song files may not be
reproduced entirely accurately when played through the instrument.
