About the Ivory Feel Keyboard
Features of an ivory feel keyboard
Traditional piano keys are made from the best materials-ivory (for
white keys) and ebony (for black keys). The Ivory Feel keyboard uses
the latest in technology to reproduce the touch and feel of these
materials.
An Ivory Feel keyboard offers the following features.
• We’re sure you’ll develop a fondness for the distinctive texture of
these keys, which feels better the more you play them.
• Surfaces incorporate stripes of moisture-absorbing material for
improved touch and playability.
• The keys feature subtle gloss and understated coloring,
enhancing the look and elegance.
• The white keys are finished with a slight yellowish tinge for the
look of real ivory.
Handling
• Do not write on the keyboard with any pen or other implement,
and do not stamp or place any marking on the instrument. Ink
will seep into the surface lines and become unremovable.
• Do not affix stickers on the keyboard. You may be unable to
remove stickers that use strong adhesives, and the adhesive
may cause discoloration.
Care and maintenance
Please note the following points. Failure to do so may result
in scratches on the surface finish, damaged gloss, or other
discoloration or deformation.
• To remove dirt, use a soft cloth.
Using a moistened and tightly wrung-out cloth, gently wipe off
any dirt.
Do not rub the surface vigorously.
• To remove stubborn dirt, use a commercially available keyboard
cleaner that does not contain abrasives.
Start by wiping lightly. If the dirt does not come off, wipe using
gradually increasing amounts of pressure while taking care not
to scratch the keys.
• Do not use benzene, paint thinner, or alcohol on the instrument.
Installing the CD Drive (Sold
separately)
Attach the CD drive as shown the figure, using the mounting holes
on the unit’s bottom panel.
• For details of the attachment or connecting, refer to the owner’s
manual of the CD drive.
MEMO
Use a CD drive sold by Roland. We cannot guarantee operation if
any other CD drive is used.
Caution when using a CD
NOTE
• You cannot play back CD-R/RW disks to which audio tracks have
been added or CDs containing both audio tracks and data (CD
Extra).
• The unit is capable of playing back only commercial CDs that
conform the official standards-those that carry the “COMPACT
DISC DIGITAL AUDIO” logo.
• The usability and sound quality of audio discs that incorporate
copyright protection technology and other non-standard CDs
cannot be guaranteed.
For more detailed information on audio discs featuring
copyright protection technology and other non-standard CDs,
please consult the disc vendor.
• You cannot save songs and styles to CDs, and you cannot delete
songs or styles recorded to CDs. Furthermore, you cannot
format CDs.
