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 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 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 dam-
age 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 PSR-
5700. 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 (wrin-
kled, 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 tamper-
ing with it in anyway can lead to irreparable damage and possibly elec-
tric shock. Refer all servicing to qualified YAMAHA personnel.
YAMAHA is not responsible for damage caused by improper handling or operation.
