IMPORTANT NOTES
291a
In addition to the items listed under “USING THE UNIT SAFELY” on page 2–4, please read and observe the following:
Power Supply: Use of Batteries
301
• 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).
302
• The AC adaptor will begin to generate heat after
long hours of consecutive use. This is normal, and is
not a cause for concern.
303a
• The use of an AC adaptor is recommended as the unit’s
power consumption is relatively high. Should you
prefer to use batteries, please use the alkaline type.
304a
• When installing or replacing batteries, always turn off the
power on this unit and disconnect any other devices you
may have connected. This way, you can prevent
malfunction and/or damage to speakers or other devices.
307
• Before connecting this unit to other devices, turn off
the power to all units. This will help prevent malfunc-
tions and/or damage to speakers or other devices.
Placement
351
• 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.
352a
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of
such receivers.
352b
• 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 off.
354b
• 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 temper-
ature extremes. Also, do not allow lighting devices
that normally are used while their light source is
very close to the unit (such as a piano light), or
powerful spotlights to shine upon the same area of
the unit for extended periods of time. Excessive heat
can deform or discolor the unit.
355b
• When moved from one location to another where the
temperature and/or humidity is very different, 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.
356
• Do not allow rubber, vinyl, or similar materials to remain
on the unit for long periods of time. Such objects can
discolor or otherwise harmfully affect the finish.
359
• Do not paste stickers, decals, or the like to this
instrument. Peeling such matter off the instrument
may damage the exterior finish.
Maintenance
401a
• 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 impreg-
nated with a mild, non-abrasive detergent. After-
wards, be sure to wipe the unit thoroughly with a
soft, dry cloth.
402
• Never use benzine, thinners, alcohol or solvents of
any kind, to avoid the possibility of discoloration
and/or deformation.
Additional Precautions
553
• 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.
556
• 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.
558a
• 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).
559a
• 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.
562
• 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.
921
• To prevent malfunction and/or damage to speakers
or other devices, always turn down the volume, and
turn off the power on all devices before making any
connections.
