IMPORTANT NOTES
291b
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY”
on pages p. 2 and p. 3, please read and observe the following:
Power Supply
301
•Do not connect this unit to same electrical outlet that
is being used by an electrical appliance that is
controlled by an inverter (such as a refrigerator,
washing machine, microwave oven, or air condi-
tioner), or that contains a motor. Depending on the
way in which the electrical appliance is used, power
supply noise may cause this unit to malfunction or
may produce audible noise. If it is not practical to
use a separate electrical outlet, connect a power
supply noise filter between this unit and the
electrical outlet.
307
• 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.
308
• Although the LCD and LEDs are switched off when
the POWER switch is switched off, this does not
mean that the unit has been completely discon-
nected from the source of power. If you need to turn
off the power completely, first turn off the POWER
switch, then unplug the power cord from the power
outlet. For this reason, the outlet into which you
choose to connect the power cord’s plug should be
one that is within easy reach.
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.
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.
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.
359
• Do not paste stickers, decals, or the like to this
instrument. Peeling such matter off the instrument
may damage the exterior finish.
Maintenance
401b
• To clean the unit, use a dry, soft cloth; or one that is
slightly dampened. Try to wipe the entire surface
using an equal amount of strength, moving the cloth
along with the grain of the wood. Rubbing too hard
in the same area can damage the finish.
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.
557
•Asmall amount of heat will radiate from the unit
during normal operation.
558b
• To avoid disturbing your neighbors, try to keep the
unit’s volume at reasonable levels (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.
565
• Due to the structural design of this instrument,
small pets or other animals could getting trapped
inside it. If such a situation is encountered, you must
immediately switch off the power and disconnect
the power cord from the outlet. You should then
consult with the retailer from whom the instrument
was purchased, or contact the nearest Roland
Service Center.
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.
