Important Notes

In addition to the items listed under "IMPORTANT SAFETY INSTRUCTIONS" and "USING THE UNIT SAFELY" on pages 2
and 3, please read and observe the following:

Power supply

• Do not use this unit on the same power circuit with any
device that will generate line noise (such as an electric
motor or variable lighting system).
• Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions
and/or damage to speakers or other devices.
Placement
• Using the unit near power amplifiers (or other equipment
containing large power transformers) may induce hum. To
alleviate the problem, change the orientation of this unit; or
move it farther away from the source of interference.
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
• To avoid possible breakdown, do not use the unit in a wet
area, such as an area exposed to rain or other moisture.
Maintenance
• 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.
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
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 memory
card, 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.

Memory backup

• This unit contains a battery which powers the unit's
memory circuits while the main power is off. When this
battery becomes weak, the message shown below will
appear in the display. Once you see this message, have the
battery replaced with a fresh one as soon as possible to
avoid the loss of all data in memory. To have the battery
replaced, consult with your retailer, the nearest Roland
Service Center, or an authorized Roland distributor, as
listed on the "Information" page.
"Checking BATTERY ... NG."
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 memory card.
4
• Unfortunately, it may be impossible to restore the contents
of data that was stored on a memory 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, sliders, 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.
• A small amount of heat will radiate from the unit during
normal operation.
• 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, package it in the box
(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.
• 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 information on
cable specifications, contact the manufacturer of the cable.
• The explanations in this manual include illustrations that
depict what should typically be shown by the display.
Note, however, that your unit may incorporate a newer,
enhanced version of the system (e.g., includes newer
sounds), so what you actually see in the display may not
always match what appears in the manual.
Before using cards

Using memory cards

• Carefully insert the memory card all the way in—until it is
firmly in place.
• Never touch the terminals of the memory card. Also, avoid
getting the terminals dirty.
