Troubleshooting
If you encounter what appears to be a malfunction, please check the follow-
ing points before assuming that your Clavinova is faulty.
1. No Sound When the Power is Turned ON
Is the AC plug properly connected to the Clavinova and an AC wall outlet? Check the AC connection
carefully. Is the MASTER VOLUME control turned up to a reasonable listening level?
Also make sure that a pair of headphones is not plugged into the PHONES jack, and the Local Control
(page 14) is ON.
2.The Damper Pedal Doesn’t Work
If the damper pedal doesn’t work, or notes are sustained even when the pedal is not pressed, make sure
that the pedal cord is properly plugged into the main unit (page 26).
3. The Clavinova Reproduces Radio or TV Sound
This can occur if there is a high-power transmitter in your vicinity. Contact your Yamaha dealer.
4. 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.
5. Interference Appears On Radio or TV Sets Located Near the Clavinova
The Clavinova contains digital circuitry which can generate radio-frequency noise. The solution is to
move the Clavinova further away from the affected equipment, or vice versa.
6.Noise is heard from the speakers or headphones.
The noise may be due to interference caused by the use of a mobile phone in close proximity to the
Clavinova.
Turn off the mobile phone, or use it further away from the Clavinova.
7. Distorted Sound When the Clavinova is Connected to An External Amplifier/Speaker System
If the Clavinova is connected to a stereo system or instrument amplifier and the sound is distorted,
reduce the volume of the external equipment to a level at which the distortion ceases.
