Important Notes
291a
In addition to the items listed under “USING THE UNIT SAFELY” on page 2-3, please read and observe the following:
Power Supply
Placement
301
352a
•
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.
•
This device may interfere with radio and television
reception. Do not 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 initi-
ating 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.
302
354a
•
The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a cause
for concern.
•
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.
303a
•
The use of an AC adaptor is recommended as the unit’s
355b
power consumption is relatively high. Should you prefer to
use batteries, please use the alkaline type.
•
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.
304a
•
When installing or replacing batteries, always turn off the
power on this unit and disconnect any other devices you
may have connected. This way, you can prevent
malfunction and/or damage to speakers or other devices.
307
•
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.
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.
Maintenance
401a
401a
•
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.
402
•
Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or defor-
mation.
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 written down on paper.
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.
4
Additional Precautions
551
•
Please be aware that the contents of memory can be
irretrievably lost as a result of a malfunction, or the
improper operation of the unit. To protect yourself against
the risk of losing important data, we recommend that you
periodically write down important data you have stored in
the unit's memory on paper.
552
•
Unfortunately, it may be impossible to restore the contents
of data that was stored in the unit’s memory once it has
been lost. Roland Corporation assumes no liability
concerning such loss of data.
553
•
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.
556
•
When connecting / 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.
558b
•
To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels (especially when it is late at
night).
559a
•
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.
561
•
Use only the specified expression pedal (EV-5; sold
separately). By connecting any other expression pedals,
you risk causing malfunction and/or damage to the unit.
Handling CD-ROMs
801
•
Avoid touching or scratching the shiny underside
(encoded surface) of the disc. Damaged or dirty CD-ROM
discs may not be read properly. Keep your discs clean
using a commercially available CD cleaner.
