TROUBLESHOOTING
MIDI DATA FORMAT
If you encounter what appears to be a malfunction, please check
the following points before assuming that your Personal Elec-
tronic Piano is faulty.
1. No Sound When the Power is Turned ON
Is the AC plug properly connected to an AC wall outlet?
Check the AC connection carefully. Is the MASTER VOLUME
control turned up to a reasonable listening level?
2. The Personal Electronic Piano Reproduces Radio or TV
Sound
This can occur if there is a high-power transmitter in your
vicinity. Contact your Yamaha dealer.
3. Intermittent Static Noise
This is usually due to turning ON or OFF a household appli-
ance or other electronic equipment which is fed by the same
AC mains line as your Personal Electronic Piano.
4. Interference Appears On Radio or TV Sets Located Near
the Personal Electronic Piano
The Personal Electronic Piano contains digital circuitry which
can generate radio-frequency noise. The solution is to move
the Personal Electronic Piano further away from the affected
equipment, or vice versa.
5. Distorted Sound When the Personal Electronic Piano is Con-
nected to An External Amplifier/Speaker System
If the Personal Electronic Piano is connected to a stereo
system or instrument amplifier and the sound is distorted,
reduce the setting of the Personal Electronic Piano volume
control to a level at which the distortion ceases.

puter to control your music hardware with computer-generated
MIDI messages, the data provided in this section can help you
to control the Personal Electronic Piano.
