IMPORTANT NOTES

291b

In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 2,
3 and 4, 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 LED are switched off when the

POWER switch is switched off, this does not mean
that the unit has been completely disconnected 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

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.

557

• A small amount of heat will radiate from the unit

during normal operation.

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.
