BK-7m

1. 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

(such as a refrigerator, washing machine, microwave oven, or air

conditioner), 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.

• The AC adaptor will begin to generate heat after long hours of

consecutive use. This is normal, and is not a cause for concern.

• 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.

Placement

• Using the BK-7m near power amplifiers (or other equipment con-

taining large power transformers) may induce hum. To alleviate

the problem, change the orientation of this instrument or move it

further away from the source of interference.

• This device may interfere with radio and television reception. Do

not use it 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 off.

• Do not expose the unit to direct sunlight, place it near devices that

radiate heat, leave it inside an enclosed vehicle, or otherwise sub-

ject it to temperature extremes. Excessive heat can deform or dis-

color the unit.

•When moved from one location to another where the temperature

and/or humidity is very different, water droplets (condensation)

may form inside the BK-7m. 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 pre-

vent this from happening. If you do so, please make sure that the

unit will not slip or move accidentally.

• 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, nonabrasive detergent.

Afterwards, be sure to wipe the unit thoroughly with a soft, dry

cloth.

• Never use benzene, thinner, 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

Corporation assumes no liability concerning such loss of data.

• Use a reasonable amount of care when using the BK-7m’s buttons,

other controls and jacks/connectors. Rough handling can lead to

malfunctions.

• Never strike or apply strong pressure to the display.

•When connecting/disconnecting 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 BK-7m’s vol-

ume at reasonable levels. You may prefer to use headphones, so

you do not need to be concerned about those around you (espe-

cially late at night).

•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.

• Use only the specified expression pedal (Roland EV-series, sold

separately) or pedal switch (Roland DP-series, BOSS FS-5U). By

connecting any other expression pedal or footswitch, you risk

causing malfunction and/or damage the unit.

• 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 man-

ufacturer of the cable.

Storage devices that can be connected to the

BK-7m’s USB MEMORY port

• The BK-7m 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-7m 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 guar-

antee operation if any other USB memory is used.

Before using external USB storage devices

•When connecting a USB memory, firmly insert it all the way into

the EXTERNAL MEMORY port.

• Do not touch the pins of the EXTERNAL MEMORY port or allow

them to become dirty.

•While using an external USB memory, please observe the following

points when handling it:

• To prevent damage from static electrical charges, discharge any

static electricity that might be present in your body before han-

dling a USB memory.

• Do not touch the terminals with your fingers or any metal

object.

• Do not bend or drop a USB memory, or subject it to strong

impact.

• Do not leave a USB memory in direct sunlight or in locations

such as a closed-up automobile.

• Do not allow a USB memory to become wet.

• Do not disassemble or modify your external USB memory.

•When connecting a USB memory, position it horizontally with the

BK-7m’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 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-7m’s USB MEMORY port.
