WARNING
DO NOT play a CD-ROM disc on a
conventional audio CD player. The result-
ing sound may be of a level that could
cause permanent hearing loss. Damage
to speakers or other system components
may result.
CAUTION
The unit should be located so that its
location or position does not interfere
with its proper ventilation.
This JUPITER-80 for use only with Roland
stand KS-J8, KS-G8, and KS-18Z. Use with
other stands is capable of resulting in
instability causing possible injury.
Even if you observe the cautions given
in the owner’s manual, certain types of
handling may allow this product to fall
from the stand, or cause the stand to
overturn. Please be mindful of any safety
issues before using this product.
Always grasp only the plug on the
power-supply cord when plugging into, or
unplugging from, an outlet or this unit.
At regular intervals, you should unplug
the power plug and clean it by using
a dry cloth to wipe all dust and other
accumulations away from its prongs.
Also, disconnect the power plug from
the power outlet whenever the unit is to
remain unused for an extended period of
time. Any accumulation of dust between
the power plug and the power outlet can
result in poor insulation and lead to fire.
Try to prevent cords and cables from
becoming entangled. Also, all cords and
cables should be placed so they are out of
the reach of children.
CAUTION
Never climb on top of, nor place heavy
objects on the unit.
Never handle the power cord or its plugs
with wet hands when plugging into, or
unplugging from, an outlet or this unit.
Before moving the unit, disconnect the
power plug from the outlet, and pull out
all cords from external devices.
Before cleaning the unit, turn off the
power and unplug the power cord from
the outlet (p. 20).
Whenever you suspect the possibility of
lightning in your area, pull the plug on the
power cord out of the outlet.
To prevent accidental ingestion of the
parts listed below, always keep them out
of the reach of small children.

IMPORTANT NOTES
Power Supply
• 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 refrig-
erator, 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.
• 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.
• Although the LCD and LEDs are switched off
when the POWER switch is switched off, this does
not mean that the unit has been completely
disconnected from the source of power. If you need
to turn off the power completely, first turn off the
POWER switch, then unplug the power cord from
the power outlet. For this reason, the outlet into
which you choose to connect the power cord’s plug
should be one that is within easy reach and readily
accessible.
Placement
• 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.
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of
such receivers.
• 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 initiating 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.
• 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.
• 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.
• 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.
• Depending on the material and temperature of the
surface on which you place the unit, its rubber feet
may discolor or mar the surface.
You can place a piece of felt or cloth under the
rubber feet to prevent this from happening. If you
do so, please make sure that the unit will not slip or
move accidentally.
• Do not put anything that contains water on this
unit. 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.
Maintenance
• 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.
• Never use benzine, thinners, alcohol or solvents of
any kind, to avoid the possibility of discoloration
and/or deformation.
Repairs and Data
• 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 backed up
USB flash drives, or written down on paper (when
possible). 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.
