IMPORTANT NOTES
Repairs and Data
•
Please be aware that all data contained in the unit’s memory may be
lost when the unit is sent for repairs. Important data should always
be backed up on a USB memory, or written down on paper (when
possible). During repairs, due care is taken to avoid the loss of data.
However, in certain cases (such as when circuitry related to memory
itself is out of order), we regret that it may not be possible to restore
the data, and Roland assumes no liability concerning such loss of
data.
Additional Precautions
•
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 USB memory.
•
Unfortunately, it may be impossible to restore the contents of data
that was stored on an Internal Memory, a USB Memory or an external
memory once it has been lost. Roland Corporation assumes no
liability concerning such loss of data.
•
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.
•
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.
•
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).
•
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.
•
Do not apply undue force to the music stand while it is in use.
•
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 information on cable specifications, contact the
manufacturer of the cable.
•
Before opening or closing the keyboard lid, always make sure that no
pets or other small animals are located on top of the instrument (in
particular, they should be kept away from the keyboard and its lid).
Otherwise, due to the structural design of this instrument, small pets
or other animals could end up getting trapped inside it. If such a
situation is encountered, you must immediately switch off the power
and disconnect the power cord from the outlet. You should then
consult with the retailer from whom the instrument was purchased,
or contact the nearest Roland Service Center.
•
A small amount of heat will radiate from the unit during normal
operation.
Handling the Floppy Disk Drive
(Using Optional Floppy Disk Drive)
•
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.
Handling Floppy Disks
•
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 temperature
range: 10 to 50 degrees C (50 to 122 degrees F).
•
Do not expose floppy disks to strong magnetic fields, such as
those generated by loudspeakers.
•
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.
•
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.
•
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.
Handling Using USB memory
(Using Optional USB memory)
•
Do not connect or disconnect USB memory while it is being read
from, or written to (i.e., while the USB memory access indicator will
blink).
•
Carefully insert the USB memory all the way in—until it is firmly in
place.
•
Never touch the External Memory connector. Also, avoid getting the
terminals dirty.
•
USB memories are constructed using precision components; handle
the USB memories carefully, paying particular note to the following.
•
To prevent damage to the USB memories from static electricity, be
sure to discharge any static electricity from your own body before
handling the USB memories.
•
Do not touch or allow metal to come into contact with the contact
portion of the USB memories.
•
Do not bend, drop, or subject USB memories to strong shock or
vibration.
•
Do not keep USB memories in direct sunlight, in closed vehicles,
or other such locations.
•
Do not allow USB memories to become wet.
•
Do not disassemble or modify the USB memories.
Handling CD-ROMs
(Using Optional CD-ROMs)
•
Avoid touching or scratching the shiny underside (encoded surface)
of the disc. Damaged or dirty CD-ROM discs may not be read
properly. Keep your discs clean using a commercially available CD
cleaner.
