IMPORTANT NOTES
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 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 lter between
this unit and the electrical outlet.
307
• Before connecting this unit to other devices, turn o the power to all
units. This will help prevent malfunctions and/or damage to speakers
or other devices.
308
• Although the LCD and LEDs are switched o when the POWER switch
is switched o, this does not mean that the unit has been completely
disconnected from the source of power. If you need to turn o the
power completely, rst turn o 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.

• Using the unit near power ampliers (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.

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
o.

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 dierent, 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.
358
• 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.
360

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.

Repairs and Data
452
• 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 USB memories, 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.

as a result of a malfunction, or the improper operation of the unit.
To protect yourself against the risk of loosing important data, we
recommend that you periodically save a backup copy of important
data you have stored in the unit’s memory on USB memories.

that was stored in the unit’s memory, or USB memories once it has
been lost. Roland Corporation assumes no liability concerning such
loss of data.
