IMPORTANT NOTES
 
291a
 
 
Power Supply
 
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.
 
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
 
352
 
• This device may interfere with radio and 
television reception. Do not use this device in 
the vicinity of such receivers.
 
354a
 
• 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.
 
355
 
• To avoid possible breakdown, do not use the 
unit in a wet area, such as an area exposed to 
rain or other moisture.
 
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
 
• 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.
 
558a
 
• To avoid disturbing your neighbors, try to 
keep the unit’s volume at reasonable levels. 
You may prefer to use headphones, so you do 
not need to be concerned about those around 
you (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.
• When you turn on the power, never push 
keys or buttons. This can be the cause of 
malfunction.
