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 conden-
sation 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. 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.
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.
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. 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.
USB Memory Handling
(Using USB Memory)
When connecting USB memory, firmly insert it all the way in.
Do not touch the pins of the USB memory connector, or allow them
to become dirty.
USB memory is made using high-precision electronic components,
so 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
handling USB memory.
Do not touch the terminals with your fingers or any metal object.
Do not bend or drop USB memory, or subject it to strong impact.
Do not leave USB memory in direct sunlight or in locations such as
a closed-up automobile. (Storage temperature: 0–50 degrees C)
Do not allow USB memory to become wet.
Do not disassemble or modify USB memory.
When connecting USB memory, position it horizontally with the USB
MEMORY 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 MEMORY connector. Doing so will
damage the USB MEMORY connector.
Do not apply excessive force to the connected USB memory.
If you will not be using USB memory for an extended period of time,
close the USB memory cover.
