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 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 15) 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 iii). 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. 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 setting of the Clavinova volume control to a level at which the distortion ceases.
