IMPORTANT NOTES

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.

• 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.

• 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

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 and readily accessible.

Placement

• 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.

• 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

off.

• 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. 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.

• 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.

• 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.

• Do not allow objects to remain on top of the keyboard or pedal board.

This can be the cause of malfunction, such as keys ceasing to produce

sound.

• Do not paste stickers, decals, or the like to this instrument. Peeling

such matter off the instrument may damage the exterior finish.

Maintenance

• 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.

• Never use benzine, thinners, alcohol or solvents of any kind, to avoid

the possibility of discoloration and/or deformation.

Repairs and Data

• Please be aware that all data contained in the unit’s memory may be

lost when the unit is sent for repairs. Important data should always be

backed up on a USB memory, or written down on paper (when

possible). During repairs, due care is taken to avoid the loss of data.

However, in certain cases (such as when circuitry related to memory

itself is out of order), we regret that it may not be possible to restore

the data, and Roland assumes no liability concerning such loss of

data.

Before Using USB Memory

Using USB memories

• Use USB memory available from Roland. Proper operation cannot be

guaranteed if other USB device is used.

• We cannot guarantee correct operation if other brands of USB

memory are used. Note that only USB memory keys can be used—

never use any other kind of USB device.

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

connector and insert it without using excessive force. The USB

MEMORY connector may be damaged if you use excessive force when

inserting USB memory.

• Do not insert anything other than USB memory (e.g., wire, coins, other

types of device) into the USB connector. Doing so will damage the

USB connector.

• Do not apply excessive force to the connected USB memory.

• Carefully insert the USB memory all the way in—until it is firmly in

place.

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

terminals dirty.

• USB memories are constructed using precision components; handle

the USB memories carefully, paying particular note to the following.

• To prevent damage to the USB memories from static electricity, be

sure to discharge any static electricity from your own body before

handling the USB memories.

• Do not touch or allow metal to come into contact with the contact

portion of the USB memories.

• Do not bend, drop, or subject USB memories to strong shock or

vibration.

• Do not keep USB memories 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 memories.
