Troubleshooting
If you encounter what appears to be a malfunction, please
check the following points before assuming that your
Clavinova 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 tumed up to a reasonable listening
level?
2. The Clavinova 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
appliance or other electronic equipment which is fed by
the same AC mains line as your Clavinova.
4. Interference Appears On Radio or TV Sets
Located Near the Clavinova
The Clavinova contains digital circuitry which can gen-
erate radio-frequency noise. The solution is to move the
Clavinova further away from the affected equipment, or
vice versa.
Distorted Sound When the Clavinova is
Connected to An External Amplifier/Speaker
System
If the Clavinova is connected to a stereo system or in-
strument amplifier and the sound is distorted, reduce the
setting of the Clavinova volume control to a level at
which the distortion ceases.

MIDI Data Format
If you're already very familiar with MIDI, or are using a
computer to control your music hardware with computer-
generated MIDI messages, the data provided in this section
can help you to control the Clavinova.
1. NOTE ON/OFF
Data format: [9xH] -> [kk] -> [vv]
9xH = Note ON event (x = channel number)
kk = Note number (21 ~ 108 = A-1 ~ C7)
vv = Velocity (Key ON = 1 ~ 127. Key OFF = 0)
* Note OFF event format [Б] -> [kk] -> [уу] also recognized
(reception only, vv = 0 ~ 127)
2. CONTROL CHANGE & MODE MESSAGES
Data format: [BxH] -> [cc] -» [dd]
BxH = Control event (x = channel number)
cc = Control number (or mode message number)
dd = Control value
