IMPORTANT NOTES

291a
In addition to the items listed under "USING THE UNIT SAFELY" on page 2, please read and
observe the following:

Power Supply:

Use of Batteries
301
• Do not use this unit on the same power circuit
with any device that will generate line noise
(such as an electric motor or variable lighting
system).
302
• The AC adaptor will begin to generate heat
after long hours of consecutive use. This is
normal, and is not a cause for concern.
303a
• The use of an AC adaptor is recommended as
the unit's power consumption is relatively
high. Should you prefer to use batteries,
please use the alkaline type.
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.
Placement
351
• 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.
352
• This device may interfere with radio and
television reception. Do not use this device in
the vicinity of such receivers.
355
• To avoid possible breakdown, do not use the
unit in a wet area, such as an area exposed to
rain or other moisture.

Maintenance

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 deformation.

Additional Precautions

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.
554
• Never strike or apply strong pressure to the
display.
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.
