volume.

2. Remove the original connector from the

headphone jack.

3. Turn on the power supply and press the

boot button.

1. Plug the pedal cord into the piano socket.

end of the pedal connection is loose or

not, and then tighten it.

This is a normal phenomenon, indicating

that the current enters the machine at this

time.

The use of mobile phones in the vicinity of

the piano produces radiation. To avoid this

situation, you can turn off the mobile phone

or use it away from the piano.

Power shortage. Check power stability.

The maximum number of simultaneous

sounds on this instrument is 128 notes. If

the dual tone mode is in use and the

accompaniment or music is playing, some

notes or sounds in the accompaniment or

music will be default.

This is a normal phenomenon. This

machine adopts AWM sound source mode.

This kind of sound source is sampled and

recorded in the whole keyboard area, so

the quality of the two notes is slightly

different.

No need to install extra drives. If the piano

isn't recognized by the computer, please

check if the USB cords are connected

securely or try to connect other USB

sockets of the computer.
