Important Notes
560
Do not pull the music stand too far forward when setting/
releasing its latches.
562
Use a cable from Roland to make the connection. If using
some other make of connection cable, please note the
following precautions.
Some connection cables contain resistors. Do not use
cables that incorporate resistors for connecting to this
unit. The use of such cables can cause the sound level
to be extremely low, or impossible to hear. For infor-
mation on cable specifications, contact the manufac-
turer of the cable.
Before Using Floppy Disks
Handling the Floppy Disk Drive
602
Install the unit on a solid, level surface in an area free from
vibration.
603
Avoid using the unit immediately after it has been moved
to a location with a level of humidity that is greatly
different than its former location. Rapid changes in the
environment can cause condensation to form inside the
drive, which will adversely affect the operation of the
drive and/or damage floppy disks. When the unit has
been moved, allow it to become accustomed to the new
environment (allow a few hours) before operating it.
604
To insert a disk, push it gently but firmly into the drive—
it will click into place. To remove a disk, press the EJECT
button firmly. Do not use excessive force to remove a disk
which is lodged in the drive.
605a
Never eject a disk while reading or writing is in progress,
since that can damage the magnetic surface of the disk,
rendering it unusable. (The disk drive’s indicator will
light up at full brightness when the drive is busy reading
or writing data. Ordinarily, the indicator will be less
brightly lit, or be extinguished.)
606
Remove any disk from the drive before powering up or
down.
607
To prevent damage to the disk drive’s heads, always try to
hold the floppy disk in a level position (not tilted in any
direction) while inserting it into the drive. Push it in
firmly, but gently. Never use excessive force.
608
To avoid the risk of malfunction and/or damage, insert
only floppy disks into the disk drive. Never insert any
other type of disk. Avoid getting paper clips, coins, or any
other foreign objects inside the drive.
Handling Floppy Disks
651
Floppy disks contain a plastic disk with a thin coating of
magnetic storage medium. Microscopic precision is
required to enable storage of large amounts of data on
such a small surface area. To preserve their integrity,
please observe the following when handling floppy disks:
Never touch the magnetic medium inside the disk.
Do not use or store floppy disks in dirty or dusty areas.
Do not subject floppy disks to temperature extremes
(e.g., direct sunlight in an enclosed vehicle). Recom-
mended temperature range: 10 to 50° C (50 to 122° F).
Do not expose floppy disks to strong magnetic fields,
such as those generated by loudspeakers.
652
Floppy disks have a “write protect” tab which can protect
the disk from accidental erasure. It is recommended that
the tab be kept in the PROTECT position, and moved to
the WRITE position only when you wish to write new
data onto the disk.
653
The identification label should be firmly affixed to the
disk. Should the label come loose while the disk is in the
