I Electrical Interference I Data Backup I Handle Floppy Disks and the Disk Drive With Care I Service and Modification G This instrument contains digital circuitry and may cause interference if placed too close to radio or television receivers. If this occurs, move the instrument further away from the affected equipment. G Internal data (e.g. sequencer data) is retained in memory even if the power switch is turned OFF. If the power is not turned ON for periods longer than about a week, however, memory data will be lost. Save all important data to disk before turning off for longer periods. G Internal memory data can be corrupted due to incorrect operation. Be sure to "save" important data to a floppy disk frequently so you have a backup to revert to if something happens to damage the data in memory. Also note that magnetic fields can damage data on the disk, so it is advisable to make a second back-up copy of disks that contain very important data, and keep backup disks in a safe place away from stray magnetic fields (i.e. away from speakers, appliances containing motors, etc.). G Do not bend or apply pressure to the floppy disk. Do not open the shutter and touch the surface of the floppy disk inside. G Do not expose the disk to high temperatures. (e.g. direct sunlight) G Use only 3.5" 2DD type floppy disks. G Do not expose the disk to magnetic fields. Magnetic fields can partially or totally erase data on the disk, rendering the disk unreadable. G To eject a floppy disk, press the eject button slowly as far as it will go then, when the disk is fully ejected, remove it by hand. The disk may not be ejected properly if the eject button is pressed too quickly, or it is not pressed in as far as it will go (the eject button may become stuck in a half-pressed position and the disk extends from the drive slot by only a few millimeters). If this happens, do not attempt to pull out the partially ejected disk. Using force in this situation can damage the disk-drive mechanism or the floppy disk. To remove a partially ejected disk, try pressing the eject button once again, or push the disk back into the slot and then repeat the eject procedure carefully. G Do not insert anything but floppy disks into the disk drive. Other objects may cause damage to the disk drive or the floppy disk. G Be sure to remove the floppy disk from the drive when moving the PSR5700. Moving the instrument while a floppy disk is loaded can damage both the drive and the disk. G Apply floppy disk labels carefully! Improperly applied disk labels (wrinkled, protruding corners, etc.) can cause the disk to become stuck in the disk drive. G The PSR-5700 contains no user serviceable parts. Opening it or tampering with it in anyway can lead to irreparable damage and possibly electric shock. Refer all servicing to qualified YAMAHA personnel. YAMAHA is not responsible for damage caused by improper handling or operation. 5
