Factory Preset Recall All dual mode, split mode, reverb, effect, touch sensitivity, tuning settings, and the settings affected by the Backup Functions can be POWER restored to their original factory preset values by holding the C7 key (rightmost key on the keyboard) while turning the [POWER] switch ON. This also erases all recorder data, and sets all Backup on/off settings (F9) to "OFF". • The factory setting list is found on page 42. 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 that the Local Control (page 34) 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 50). 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 Clavinova's speakers. 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. q If "Scn" appears on the display an internal malfunction has occurred. In this case, contact your Yamaha dealer. Options & Expander Modules q Options q Expander Modules HPE-160 Stereo Headphones High-performance lightweight dynamic headphones with extra-soft ear pads.
