IMPORTANT NOTES
291b
In addition to the items listed under “Important Safety Instructions” (inside cover) and “Using the unit safely”, p. 2,
please read and observe the following:
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).
307
• When the AC adaptor is used for extended periods, both
the adaptor itself, and the area around the ep-760’s DC IN
connector will become somewhat warm; however, this
does not indicate a malfunction.
• Before connecting the ep-760 to other devices, turn off the
power to all units. This will help prevent malfunctions
and/or damage to speakers or other devices.
• Be sure to only use the supplied adapter or (in the
unlikely event it ceases to function properly) an equiva-
lent Roland ACO adapter.
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 interfer-
ence.
352a
• This instrument 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 initiat-
ing 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.
354b
• Do not expose the unit to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed vehi-
cle, or otherwise subject it to temperature extremes. Also,
do not allow lighting devices that normally are used while
their light source is very close to the unit (such as a piano
light), or powerful spotlights to shine upon the same area
of the unit for extended periods of time. Excessive heat
can deform or discolor the unit.
355
• To avoid possible breakdown, do not use the ep-760 in a
wet area, such as an area exposed to rain or other mois-
ture.
356
• Do not allow rubber, vinyl, or similar materials to remain
on the ep-760 for long periods of time. Such objects can
discolor or otherwise harmfully affect the finish.
357
• Do not put anything that contains water (e.g., flower
vases) on the piano. Also, avoid the use of insecticides,
perfumes, alcohol, nail polish, spray cans, etc., near the
unit. Swiftly wipe away any liquid that spills on the unit
using a dry, soft cloth.
358
• Do not allow objects to remain on the keyboard. This can
be the cause of malfunction, such as keys ceasing to pro-
duce sound.
Maintenance
401b
• To clean the unit, use a dry, soft cloth; or one that is
slightly dampened. Try to wipe the entire surface using an
equal amount of strength, moving the cloth along with the
grain of the wood. Rubbing too hard in the same area can
damage the finish.
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 ep-760’s
buttons, sliders, or other controls; and when using its jacks
and connectors. Rough handling can lead to malfunctions.
556
• When connecting/disconnecting cables, grasp the connec-
tor itself—never pull on the cable. This way you will avoid
causing shorts, or damage to the cable’s internal elements.
557
• A small amount of heat will radiate from the unit during
normal operation.
558a
• To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels. You may prefer to use head-
phones.
559b
• When you need to transport the unit, pack it in shock-
absorbent material. Transporting the unit without doing
so can cause it to become scratched or damaged, and
could lead to malfunction.
560
• Use a cable from Roland to make the connection. If using
some other make of connection cable, please note the fol-
lowing precautions.
• Some connection cables contain resistors. Do not use
cables that incorporate resistors for connecting to this
unit. The use of such cables can cause the sound level
to be extremely low, or impossible to hear. For infor-
mation on cable specifications, contact the manufac-
turer of the cable.
