Some notes are cut off while they are playing. Notes are cut off whenever the number of notes being sounded 
exceeds the maximum polyphony value of 48 (24 for some tones). This 
does not indicate malfunction. See “Maximum Polyphony” in the “Tone 
List” in the separate “Appendix”.
The volume or tone setting I made has changed. Adjust the main volume setting (page E-6).
 Turn power off and then back on to initialize all keyboard settings 
(page E-6).
 Replace the batteries with new ones or switch over to AC adaptor 
power (page E-5).
Output volume does not change even though is 
change my keyboard touch. Change the Touch Response setting (page E-8).
 Turn power off and then back on to initialize all keyboard settings 
(page E-6).
In certain keyboard ranges, the volume and tone 
quality sound are slightly different from those in other 
keyboard ranges.This is due to system limitations. It does not indicate malfunction.
With some tones, octaves do not change at the far 
ends of the keyboard.This is due to system limitations. It does not indicate malfunction.
The pitch of the notes does not match other 
accompanying instruments or sounds strange when 
played long with other instruments. Check and adjust the transpose (page E-13) and tuning settings 
(page E-13).
 Turn power off and then back on to initialize all keyboard settings 
(page E-6).
The reverb of notes seems to change suddenly.  Check and adjust the reverb setting (page E-12).
 Turn power off and then back on to initialize all keyboard settings 
(page E-6).
A loud ringing sound is produced when I connect a 
microphone.Point the microphone away and move it away from the speakers.
Sounds I sampled were deleted. Sampled data is deleted whenever keyboard power is turned off (page 
E-15).
Operation
When I perform a skip forward or skip back 
operation, the skip operation moves multiple song 
measures instead of only a single measure.While song playback is stopped or a Step Up Lesson is in progress, 
skip forward and skip back operations are performed in phrase units 
(page E-18).
Computer Connection
I can’t exchange data between the Digital Keyboard 
and a computer. Check to make sure that the USB cable is connected to the 
keyboard and computer, and that the device is selected correctly 
with your computer’s music software settings (page E-34).
 Turn off the keyboard and then exit the music software on your 
computer. Next, turn the keyboard back on and then restart the 
music software on your computer.
