Problem Possible Cause and Solution
The H01 does not turn on. 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).
A click or pop is heard when the power is
turned on or off.
This is normal when electrical current is being applied to the instrument.
Noise is heard from the speakers or head-
phones.
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 overall volume is low, or no sound is
heard.
• 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).
The 50 Piano Preset songs cannot be
played.
Make sure that a USB storage device is not connected to the [USB TO DEVICE] ter-
minal.
The sustain pedal has no effect. The pedal cable/plug may not be properly connected. Make sure to securely insert
the pedal plug into the proper jack (page 24).
There is a slight difference in sound quality
among different notes played on the key-
board.
This is normal and is a result of the sampling system.
