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.
Service and Modification
• The QY300 contains no user serviceable parts.
Opening it or tampering with it in any way can
lead to irreparable damage and possibly electric
shock. Refer all servicing to qualified YAMAHA
personnel.
