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.
