Appendix V. Troubleshooting

This section provides solutions to common problems encountered with the keyboard:

Problem: A slight noise is heard when turning the power on or off.: Solution: This is normal and nothing to worry about.
Problem: After turning on the keyboard, no sound is heard when keys are pressed.: Solution: Verify that the volume is set correctly. Check if headphones or any other equipment are connected to the keyboard, which would automatically disconnect the built-in speaker system. Ensure that "Fingered Chords" mode is not selected, as incorrect key presses in this mode will not produce sound.
Problem: The sound is distorted or interrupted, and the keyboard is not functioning correctly.: Solution: This may be due to using an incorrect power adapter. Use the supplied power adapter or replace the batteries if necessary.
Problem: There is a slight difference in timbre for some notes.: Solution: This is normal and caused by the different voice sampling ranges of the keyboard.
Problem: When using the sustain function, some tones have long sustain and some have short sustain.: Solution: This is normal. The optimal sustain length for different tones has been pre-configured.
Problem: The main volume or accompaniment volume is incorrect.: Solution: Check that the main volume and accompaniment volume are set correctly. Note that the main volume also affects the accompaniment volume.
Problem: In SYNC mode, automatic accompaniment does not work.: Solution: Verify that "Chord" mode has been selected and then play a note on one of the 19 keys on the left side of the keyboard.
Problem: The note tone is incorrect.: Solution: Check that transposition is set to 00.
Problem: The keyboard turns off unexpectedly.: Solution: This is not a fault. The keyboard has an energy-saving function that turns it off after a period of inactivity. Press the power (on/off) button to turn it back on.
Problem: The left-side keys (first 19 keys) do not emit sound.: Solution: Verify that "FINGERED CHORD" mode has not been selected. Note that sound will only be produced when a correct chord pattern is played. Refer to Appendix VI, "Fingered Chords".
