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 recom-
mend that you periodically save a backup copy of
important data you have stored in the unit's memory
on an SD card, an SDHC card, or a computer.
• Unfortunately, it may be impossible to restore the
contents of data that was stored in the unit's memory,
an SD card or an SDHC card 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, or other controls; and when using its
jacks and connectors. Rough handling can lead to
malfunctions.
• Never strike or apply strong pressure to the display.
• 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.
• 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.
• 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.
Using SD cards
• Carefully insert the SD card or the SDHC card all the
way in—until it is firmly in place.
• Never touch the terminals of the SD card or the SDHC
card. Also, avoid getting the terminals dirty.
• SD cards and SDHC cards are constructed using
precision components; handle the cards carefully,
paying particular note to the following.
• To prevent damage to the cards from static
electricity, be sure to discharge any static electricity
from your own body before handling the cards.
• Do not touch or allow metal to come into contact
with the contact portion of the cards.
• Do not bend, drop, or subject cards to strong shock
or vibration.
• Do not keep cards in direct sunlight, in closed
vehicles, or other such locations.
• Do not allow cards to become wet.
• Do not disassemble or modify the cards.
Handling CDs / DVDs
• Avoid touching or scratching the shiny underside
(encoded surface) of the disc. Damaged or dirty discs
may not be read properly. Keep your discs clean using
a commercially available disc cleaner.
