11 Appendix Error Messages Errors do occur from time to time, and when they do the QY22 will usually display a message that indicates what type of problem has occurred so you can rectify it and return to normal operation as quickly as possible. Illegal Input This error appears if you attempt to enter a value that is out of range or otherwise unacceptable in the current situation. Memory Full The QY22 memory is full or almost full and the specified operation cannot be performed. Delete unwanted song and/or pattern data to make more memory available. Battery Low The battery voltage is too low for proper opera- tion. The sound may also become distorted when this display appears. Replace the old batteries with a set of new ones as soon as possible. Internal data will be retained while the batteries are replaced. Backup Batt. Low Appears when the power is turned on if the inter- nal memory backup battery is too low to maintain the internal memory data. Have the backup battery replaced by qualified Yamaha service personnel. Now Working This error may appear if a data error is detected when the QY22 power is turned on. The "Now Working" display indicates that the data is being repaired ... wait a few moments until the error message disappears. Preset Pattern Since the preset patterns cannot be changed in any way, this error message will appear if you attempt to execute any operation that is intended to alter the pattern data while a preset pattern is selected. Repeat Exist This error message will appear if you copy a chord part using the song job copy measure function while one or more repeats exist in the accompaniment tracks. Delete all repeats in the step record mode and then execute the copy measure function as required. 186
