Error Messages For (format) Pro (protected) dEr (disk error) The loaded disk is not formatted for use with the Clavinova. After making sure that the disk does not contain any important data (for another device, for example), format the disk as described on page 24. You have attempted to format, write to, copy to/from, or delete data from a write-protected disk. Use a disk that is not write protected (set the disk's write-protect tab to the write-enable position). An error occurred while writing to or reading from the disk. Try the operation again; if the error occurs a second time the disk or drive may be faulty. If the drive has been in use for some time the heads may be dirty. Clean the heads with a commercially-available floppy disk head cleaner. If the error still occurs with one disk and not others the disk should be considered faulty and should be discarded. If the error occurs with all disks the drive may be faulty. Refer the problem to your Yamaha dealer. no (no disk/no data) A disk read or write operation was attempted but no disk is present in the disk drive, or the song contains no appropriate data. Make sure an appropriate disk is inserted in the disk drive, or the song contains appropriate data before performing any operation that involves disk access. You have attempted to record or edit data that is not recognized by the CLP-156. Refer to the notes on pages 19, and 27. 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 turned 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 generate radio-frequency noise. The solution is to move the Clavinova further away from the affected equipment, or vice versa. 5. 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.
