Roland Piano 用户手册

401a

• For everyday cleaning wipe the unit with a soft, dry cloth or one 

that has been slightly dampened with water. To remove stubborn 
dirt, use a cloth impregnated with a mild, non-abrasive detergent. 
Afterwards, be sure to wipe the unit thoroughly with a soft, dry 
cloth.

402

• Never use benzine, thinners, alcohol or solvents of any kind, to 

avoid the possibility of discoloration and/or deformation.

551

• Please be aware that the contents of memory can be irretrievably 

lost as a result of a malfunction, or the improper operation of the 
unit. To protect yourself against the risk of loosing important data, 
we recommend that you periodically save a backup copy of 
important data you have stored in the unit’s memory on a floppy 
disk.

552

• Unfortunately, it may be impossible to restore the contents of data 

that was stored on a floppy disk, in the unit’s memory or another 
MIDI device (e.g., a sequencer) once it has been lost. Roland 
Corporation assumes no liability concerning such loss of data.

553

• Use a reasonable amount of care when using the unit’s buttons, 

sliders, or other controls; and when using its jacks and connectors. 
Rough handling can lead to malfunctions.

554

• Never strike or apply strong pressure to the display.

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).

559a

•  When you need to transport the unit, package it in the box 

(including padding) that it came in, if possible. Otherwise, you 
will need to use equivalent packaging materials.

561

• Use only the specified expression pedal (EV-5; sold separately). By 

connecting any other expression pedals, you risk causing 
malfunction and/or damage to the unit.

602

• Install the unit on a solid, level surface in an area free from 

vibration. If the unit must be installed at an angle, be sure the 
installation does not exceed the permissible range: upward, 2°; 
downward, 18°.

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 attempt to remove a floppy disk from the drive while the 

drive is operating (the indicator is lit); damage could result to both 
the disk and the drive.

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.

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). Recommended temper-
ature 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.
