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 refrigerator,
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.
• The AC adaptor will begin to generate heat after
long hours of consecutive use. This is normal, and is
not a cause for concern.
• 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.
• With the factory settings, the unit’s power will
automatically be switched off 30 minutes after you
stop playing or operating the unit.
If the unit’s power has been turned off
automatically, you can use the [Power] switch to
turn the unit back on again.
If you don’t want the power to turn off
automatically, change the “Auto Off” setting
to “OFF” as described on “Making the power
automatically turn off after a time (Auto Off)” (p. 27).
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. 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.
• 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 rubber, vinyl, or similar materials to
remain on this unit for long periods of time. Such
objects can discolor or otherwise harmfully affect
the finish.
• 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.
• Do not paste stickers, decals, or the like to this
instrument. Peeling such matter off the instrument
may damage the exterior finish.
• Do not put anything that contains water (e.g.,
flower vases) 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.
• 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.
Maintenance
• 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.
• Never use benzine, thinners, alcohol or solvents of
any kind, to avoid the possibility of discoloration
and/or deformation.
• The pedals of this unit are made of brass.
Brass eventually darkens as the result of the natural
oxidization process. If the brass becomes tarnished,
polish it using commercially available metal
polisher.
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 to a USB memory, 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.
Care of the keyboard
• Do not write on the keyboard with any pen or other
implement, and do not stamp or place any marking
on the instrument Ink will seep into the surface
lines and become unremovable.
• Do not affix stickers on the keyboard. You
may be unable to remove stickers that use
strong adhesives, and the adhesive may cause
discoloration.
• To remove stubborn dirt, use a commercially
available keyboard cleaner that does not contain
abrasives. Start by wiping lightly. If the dirt does not
come off, wipe using gradually increasing amounts
of pressure while taking care not to scratch the
keys.
Additional Precautions
• Please be aware that the contents of memory can
be irretrievably lost as a result of a malfunction, or
the improper operation of the F-120R. To protect
yourself against the risk of loosing important data,
we recommend that you periodically save a backup
copy of important data you have stored in the unit’s
memory on the USB memory.
• Unfortunately, it may be impossible to restore
the contents of data that was stored in the unit’s
memory once it has been lost. Roland Corporation
assumes no liability concerning such loss of data.
• 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.
• Never strike or apply strong pressure to the display.
• 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.
• 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.
• The sound of keys being struck and vibrations
produced by playing an instrument can be
transmitted through a floor or wall to an
unexpected extent. In particular, when using
headphones, please take care not to cause
annoyance to others nearby.
• 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.
• 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 information on cable specifications,
contact the manufacturer of the cable.
