I can’t find something that should be here. Carefully check inside all of the packing materials.
Power Requirements
Power will not turned on. • Check the AC adaptor or make sure that the batteries are facing
correctly (page E-5).
• Replace the batteries with new ones or switch over to AC adaptor
power (page E-5).
The Digital Keyboard outputs a loud sound and then
suddenly powers down. Replace the batteries with new ones or switch over to AC adaptor
power (page E-5).
The Digital Keyboard suddenly powers down after a
few minutes. This happens when Auto Power Off (page E-6) is triggered.
Display
If I don’t play anything for a few minutes, keyboard
keys suddenly start flashing. Things return to normal
after I press a keyboard key or a button. Turn off the power on alert feature (page E-6).
The display keeps going out or are flashing. Replace the batteries with new ones or switch over to AC adaptor
power (page E-5).
On-screen keyboard keys or notes remain on the
display. A Step Up Lesson is in progress and the Digital Keyboard is waiting
for you to play the next note in the song. To stop this from happening,
cancel the lesson (page E-21).
Screen contents are visible only from straight ahead. This is dues to production limitations. It does not indicate malfunction.
Sound
Nothing happens when I press any keyboard key. • Adjust the main volume setting (page E-6).
• Check if something is plugged into the PHONES/OUTPUT jack (
dn )
on the back of the Digital Keyboard.
• Turn power off and then back on to initialize all keyboard settings
(page E-6).
Nothing happens or notes do not play normally when
I play notes on the left side of the keyboard. Press bm to disable chord input in the accompaniment keyboard area
(page E-28).
Nothing happens when I start an Auto
Accompaniment. • With rhythms 140, and 142 to 150, nothing will sound until you play
a chord on the keyboard. Try playing a chord (page E-28).
• Check and adjust the accompaniment volume setting (page E-31).
• Turn power off and then back on to initialize all keyboard settings
(page E-6).
Nothing happens when I start playback of a built-in
song. • It takes a little time after you press the button until the song starts to
play. Wait for a moment for the song to start.
• Check and adjust the song volume (page E-17).
• Turn power off and then back on to initialize all keyboard settings
(page E-6).
The metronome does not sound. • Check and adjust the accompaniment volume setting (page E-31).
