Troubleshooting

Problem
The H01 does not turn on.
A click or pop is heard when the power is
turned on or off.
Noise is heard from the speakers or head-
phones.
The overall volume is low, or no sound is
heard.
The 50 Piano Preset songs cannot be
played.
The sustain pedal has no effect.
There is a slight difference in sound quality
among different notes played on the key-
board.
Possible Cause and Solution
The H01 has not been plugged in properly. Securely insert the female plug into the
socket on the H01, and the male plug into a proper AC outlet (page 10).
This is normal when electrical current is being applied to the instrument.
The noise may be due to interference caused by the use of a mobile phone in close
proximity to the H01. Turn off the mobile phone, or use it further away from the H01.
• The Master Volume is set too low; set it to an appropriate level using the [MASTER
VOLUME] control.
• Make sure a pair of headphones is not connected to the headphones jack
(page 10).
Make sure that a USB storage device is not connected to the [USB TO DEVICE] ter-
minal.
The pedal cable/plug may not be properly connected. Make sure to securely insert
the pedal plug into the proper jack (page 24).
This is normal and is a result of the sampling system.
