No Sound is Produced From the Keyboard ¶ 

The keyboard won’t output sound or the sound quality is poor.

Press the button labeled "ACCOMP" in order to the disable chord input in the accompaniment area of the keyboard. This enables the accompaniment function of the keyboard.

No sound is produced when a key is pressed ¶ 

The volume might be turned to a low setting, try turning the volume up.

Check to see if there are any headphones plugged into the headphone jack.

If there isn’t a sampled sound in memory, nothing will be able to play if a tone within the range of 601 to 608 is selected.

Try turning the keyboard off and then on again so that the keyboard's settings are reset.

Continual Sound Output with No Input ¶ 

Sound is continually produced, even when no keys are pressed on the keyboard.

Notes keep playing, even when no key is pressed ¶ 

Turn the power off and on again so that the keyboard's settings are reset.

Try replacing the batteries (they might be dead) or switch over to AC adapter power.

Turn the keyboard off and on again so that the keyboard settings reset.

Audio Distortion ¶ 

The keyboard sounds broken or disjointed

Sound quality is not consistent within different ranges of the keyboard ¶ 

This is not a malfunction of the keyboard, but a limitation.

Octaves do not change at the far end of the keyboard ¶ 

This is not a malfunction of the keyboard, but a limitation.

Display Does not Turn on Correctly ¶ 

The LCD display is unusually dim, or does not light up at all.

Low battery ¶ 

The battery power may be low. Try replacing the batteries with fresh ones. To do this, follow the Low Battery Guide

To disable this feature, when you turn on the keyboard for use, press and hold the TONE button (upper button to the right of LCD display) while turning on power.

Sticky Keys ¶ 

The keys stick down when pressed or are harder than normal to push.

Contaminates under the key ¶ 

When the key is harder than normal to push, there might be something stuck underneath the key. Try using compressed air to dislodge the contaminates. You can use quick blasts of air from different angles to thoroughly clean the underside of the key.

If the key is still difficult to press, you might have to remove the key and try and physically remove the contaminate. Once the key is removed, thoroughly clean the key with soap and water and then reinstall it.

Key is dirty ¶ 

If a key is sticky, you might have to clean underneath it. To do this the key must be removed. Do this by following the guides for replacing White Keys and Black Keys. After removing the key, try using soap and water to completely clean it, then reinstall the key.

MIDI cables are not plugged in and configured correctly ¶ 

Ensure that all MIDI cables are correctly plugged in, so that the IN is plugged into OUT on the keyboard and OUT is plugged into IN on the keyboard. Ensure that these are correctly configured with the computer.

Local Control is turned off ¶
