Data Backup

•The QY300 contains a special long-life battery that retains the contents of its internal memory even when the power is turned OFF. The backup battery should last for several years. When the backup battery needs to be replaced “Battery Low” will appear on the display when the power is turned on. When this happens, have the backup battery replaced by qualified Yamaha service personnel. DO NOT ATTEMPT TO REPLACE THE BACKUP BATTERY YOURSELF!

•Internal memory data can be corrupted due to incorrect operation. Be sure to save important data to floppy disk frequently so you have a backup to revert to if something happens to dam- age the data in memory. Also note that magnetic fields can damage data on the disk, so it is advis- able 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 con- taining motors, etc.).

Handle Floppy Disks and the Disk Drive With Care

•Use only 3.5” 2DD type floppy disks.

•Do not bend or apply pressure to the floppy disk. Do not open the shutter and touch the surface of the floppy disk inside.

•Do not expose the disk to high temperatures. (e.g. direct sunlight, a car interior, etc.)

•Do not expose the disk to magnetic fields. Mag- netic fields can partially or totally erase data on the disk, rendering the disk unreadable.

•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 be- come 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 mecha- nism 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.

•Do not insert anything but floppy disks into the disk drive. Other objects may cause damage to the disk drive or the floppy disk.
