IMPORTANT NOTES
Power Supply
• Before connecting this unit to other devices, turn o the
power to all units. This will help prevent malfunctions
and/or damage to speakers or other peripheral devices.
Placement
• Using the unit near power ampliers (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.
• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the vicinity
of this unit. Such noise could occur when receiving
or initiating a call, or while conversing. Should you
experience such problems, you should relocate such
wireless devices so they are at a greater distance from
this unit, or switch them o.
• Do not expose the unit to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed
vehicle, or otherwise subject it to temperature extremes.
Excessive heat can deform or discolor the unit.
• When moved from one location to another where the
temperature and/or humidity is very dierent, water
droplets (condensation) may form inside the unit.
Damage or malfunction may result if you attempt to use
the unit in this condition. Therefore, before using the
unit, you must allow it to stand for several hours, until
the condensation has completely evaporated.
• Depending on the material and temperature of the
surface on which you place the unit, its rubber feet may
discolor or mar the surface.
You can place a piece of felt or cloth under the rubber
feet to prevent this from happening. If you do so,
please make sure that the unit will not slip or move
accidentally.
• Do not put anything that contains water (e.g., a ower
vase) on this unit. Also, avoid the use of insecticides,
perfumes, alcohol, nail polish, spray cans, etc., near the
unit. Swiftly wipe away any liquid that spills on the unit
using a dry, soft cloth.
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 written down on
paper (when possible). During repairs, due care is taken
to avoid 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 such
data, and Roland assumes no liability concerning such
loss of data.

IMPORTANT NOTES
Additional Precautions
• Please be aware that contents in memory can be
irretrievably lost as a result of a malfunction, or 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.
• Unfortunately, it may be impossible to restore the
contents of data that was stored in the unit’s 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.
• 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 specications, contact the manufacturer of the
cable.
