Roland AT20s Before Using Floppy Disks, Handling Floppy Disks, Handling the Floppy Disk Drive

IMPORTANT NOTES

556

•When connecting / disconnecting all cables, grasp the connector itself—never pull on the cable. This way you will avoid causing shorts or damage to the cable’s internal

elements.

557

• A small amount of heat will radiate from the unit during normal operation.

\558a

•To avoid disturbing your neighbors, try to keep the unit’s volume at reasonable levels. You may prefer to use headphones, so you do not need to be concerned about

those around you (especially when it is late at night).

\559b

•When you need to transport the unit, pack it in shock- absorbent material. Transporting the unit without doing so can cause it to become scratched or damaged, and

could lead to malfunction.

560

• Do not apply undue force to the music stand while it is in use.

\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

drive, it may be difficult to remove the disk.

654

•Store all disks in a safe place to avoid damaging them, and to protect them from dust, dirt, and other hazards. By using a dirty or dust-ridden disk, you risk damaging the

disk, as well as causing the disk drive to malfunction.

655

•Disks containing performance data for this unit should always be locked (have their write protect tab slid to the “Protect” position) before you insert them into the drive on some other unit (except the PR-300, or a product in the HP-G, MT, KR, or Atelier families), or into a computer’s drive. Otherwise (if the write protect tab remains in the “Write” position), when you perform any disk operations using the other device’s disk drive (such as checking the contents of the disk, or loading data), you risk rendering the disk unreadable by this unit’s disk drive.
