2. Important Notes

In addition to the items listed under “Using the unit safely” on p. 4, please read and observe the following:

Power Supply

• Do not connect this unit to same electrical outlet

that is being used by an electrical appliance that

is controlled by an inverter or a motor (such as a

refrigerator, washing machine, microwave oven, or

air conditioner). 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 lter

between this unit and the electrical outlet.

• The AC adaptor will begin to generate heat after

long hours of consecutive use. This is normal, and is

not a cause for concern.

• To prevent malfunction and equipment failure,

always make sure to turn o the power on all your

equipment before you make any connections.

• With the factory settings, the BK-3 will

automatically be switched o 30 minutes after you

stop playing or operating the unit. If you don’t want

the unit to turn o automatically, change the “AUTO

OFF” setting to “OFF” as described on p. 52.

NOTE

The settings you were editing will be lost when the

unit is turned o. If you want to keep your settings,

you must save your settings before turning the

unit o.

Placement

• Using the unit near power ampliers (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 dierent,

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.

• Do not allow objects to remain on top of the

keyboard. This can be the cause of malfunction,

such as keys ceasing to produce sound.

• 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 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.

Additional Precautions

• Unfortunately, it may be impossible to restore the

contents of data that was stored on a USB memory

once it has been lost. Roland Europe 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 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 others nearby, 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.

• Do not apply undue force to the music stand while

it is in use.

Storage devices that can be connected

to the BK-3’s USB MEMORY port

• The BK-3 allows you to connect commercially

available USB Flash memory. You can purchase

such devices at a computer store, a digital camera

dealer, etc.

• Though external hard disks with a capacity in

excess of 2TB can be used, please bear in mind that

the BK-3 can manage a maximum of 2TB. (FAT-32

formatted storage devices can be used right away.)

• Use USB memory sold by Roland (M-UF-series).

We cannot guarantee operation if any other USB

memory is used.

Before using external USB storage

devices

• Carefully insert the USB memory all the way in—

until it is rmly in place.

• USB memories are constructed using precision

components; handle the storage devices carefully,

paying particular note to the following.

• To prevent damage to the USB memory from

static electricity, be sure to discharge any static

electricity from your own body before handling

the cards.

• Do not touch or allow metal to come into

contact with the contact portion of the USB

memory.

• Do not bend, drop, or subject cards to strong

shock or vibration.

• Do not keep cards in direct sunlight, in closed

vehicles, or other such locations.

• Do not allow USB memories to become wet.

• Do not disassemble or modify the USB memory.

• Never touch the terminals of the USB memory. Also,

avoid getting the terminals dirty.

• When connecting a USB memory, position it

horizontally with the BK-3’s USB MEMORY port

and insert it without using excessive force. The

USB MEMORY port may be damaged if you use

excessive force when inserting a USB memory.

• Do not connect or disconnect a USB drive while it

is being rear from, or written to (i.e., while the USB

ash access indicator blinks).

• Do not insert anything other than a USB memory

(e.g., wire, coins, other types of device) into the USB

MEMORY port. Doing so will damage the BK-3’s USB

MEMORY port.

• Never connect your USB memory to the BK-3 via a

USB hub.

• Do not connect or disconnect a USB drive while it

is being rear from, or written to (i.e., while the USB

ash access indicator blinks).

performance, or broadcast of copyrighted material
