Power Requirements
Power will not turned on. • Check the AC adaptor or make sure that the batteries are facing
correctly (page EN-5).
• Replace the batteries with new ones or switch over to AC adaptor
power (page EN-5).
• You may have tried to perform some operation while the “Pls wait”
message was displayed, which caused an internal problem. If other
measures do not correct this problem, perform the operation below

Screen contents are visible only from straight ahead. This is dues to production limitations. It does not indicate malfunction.

PHONES/OUTPUT jack

I play notes on the left side of the keyboard. Press bm to disable chord input in the accompaniment keyboard area
(page EN-16).
Nothing happens when I start an Auto
Accompaniment. • With rhythms D19 to D28, nothing will sound until you play a chord
on the keyboard. Try playing a chord (page EN-16).

Notes keep sounding, without stopping. • Turn power off and then back on to initialize all Digital Keyboard
settings (page EN-6).

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.
