PROBLEM
It does not switch on
No sound when the keyboard is played.
The automatic accompaniment does not play.
No sound is produced when the MIDI data are reproduced
from a computer.
Reproduction on the keyboard produces an unnatural sound
when the keyboard is connected to a computer.
When a mobile phone is used you can hear a noise.
No sound is produced even when the keyboard is played or
reproducing a song.
The sound of the voice changes from note to note.
Any other anomalies.
POSSIBLE CAUSE AND SOLUTION
Problem with the power supply.
Connect the adaptor correctly. Ensure that the battery poles (+/-) are facing the correct
direction, and control that the batteries are charged.
The volume is set at a level that is too low.
Use the VOLUME MASTER keys to raise the volume.
The accompaniment volume is set at 0.
Use the VOLUME ACCOMP. keys to raise the volume.
The USB-MIDI cable is not connected properly.
Connect the USB-MIDI cable properly.
The MIDI THRU function of the computer is activated.
Deactivate the MIDI THRU function of the computer.
The use of a mobile phone near to the computer may cause interference.To prevent this
problem, switch the mobile phone off or use it at a distance from the keyboard.
Control that the headphones are not connected to the PHONES/OUTPUT socket of
the rear panel. When headphones are connected to this socket, no sound is trans-
mitted.
The method of sound generation uses multiple recordings (samples) of one instrument
on the whole extension of the keyboard. It is therefore normal that the sound of the voice
differs slightly from note to note.
Switch off and then switch back on after a few seconds
