Troubleshooting

Problem	Possible Reason / Solution
A faint noise is heard when turning the power on or off.	This is normal and

nothing to worry about.
After turning the power on to the keyboard there was no sound when the keys were pressed.| Check the volume is set to the correct setting. Check that headphones or any other equipment are not plugged into the keyboard as these will cause the built-in speaker system to cut off automatically.
Sound is distorted or interrupted and the keyboard is not working properly.| Use of incorrect power adapter or the batteries may need replacing. Use the power adapter supplied.
There is a slight difference in the timbre of some notes.| This is normal and is caused by the many different tone sampling ranges of the keyboard.
When using the sustain function some tones have long sustain and some short sustain.| This is normal. The best length of sustain for different tones has been pre-set.
In SYNC status the auto accompaniment does not work.| Check to make sure that Chord mode has been selected and then play a note from the first 19 keys on the left-hand side of the keyboard.
