 Pedals
Issue
The pedals are unreliable or do not
function at all.
When depressing a pedal, the pedal board
flexes and is not firm.
 Headphones
Issue
The headphone volume is too low.
The headphone output sounds strange.
 USB (memory device)
Issue
A USB memory device is not detected,
cannot be saved to, or does not appear
to function when connected to the "USB
to Device" port.
The instrument pauses briefly when
connecting a USB memory device.
 USB MIDI, MIDI, Bluetooth® MIDI
Issue
The instrument is connected to the
computer using a USB cable, however the
software does not respond to key presses.
The instrument cannot connect to the
smart device/app via Bluetooth.
Possible Cause and Solution
Check that the pedal cable is firmly connected to the instrument (CA79
only).
Check that the pedal support bolt is fully extended.
Possible Cause and Solution
If the "Nominal Impedance" specification of the headphones is less than 100
Ω (ohms), set the "Headphone Volume" setting in the Speaker/Headphone
menu to High.
Check that the "Spatial Headphone Sound" and "Headphone Type" settings
are set to "Normal".
Possible Cause and Solution
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 device. If the USB device still does not function, it may be
damaged or incompatible. Please try using a different USB device.
This is recognised behaviour when using large capacity (e.g. 8GB+) USB
memory devices.
Possible Cause and Solution
Check that a USB MIDI driver is installed on the computer.
Check that "USB Audio Device" or "KAWAI USB MIDI" is selected in the
software's input/output device settings.
Check that the instrument is not connected to a smart device using
Bluetooth MIDI.
Check that the instrument's Bluetooth MIDI/Audio function is turned On.
Ensure that the mobile device's Bluetooth function is turned On.
Ensure that the instrument isn't already connected to another Bluetooth
device.
Try deleting the instrument's Bluetooth connection using the mobile
device's "Forget Device" function.
Try turning the instrument Off and then On, and/or restarting the mobile
device.
