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 or a motor (such as a refrigerator,
washing machine, microwave oven, or air
conditioner). 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 lter 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.
• To prevent malfunction and equipment
failure, always make sure to turn o the
power on all your equipment before you
make any connections.
• With the factory settings, the GT-100 will
automatically be switched o 10 hours after
you stop playing or operating the unit. If you
don’t want the unit to turn o automatically,
change the “AUTO OFF” setting to “OFF” as
described on p. 42.
* The settings you were editing will be lost
when the unit is turned o. If you want to
keep your settings, you must save your
settings before turning the unit o.
Placement
• Using the unit near power ampliers (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 o.
• 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 dierent, 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.
• 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 computer, in another
MIDI device, 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.
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 unit. 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 a computer, or in another MIDI
device.
• Unfortunately, it may be impossible to
restore the contents of data that was stored
in the unit’s memory, on a computer, or in
another MIDI device 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 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 others nearby, 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.
• 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.
• Use only the specied expression pedal
(Roland EV-5, BOSS FV-500L, BOSS FV-
500H; sold separately). By connecting any
other expression pedals, you risk causing
malfunction and/or damage to the unit.
• 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 specications, contact
the manufacturer of the cable.
• When you operate the expression pedal,
please be careful not to get your ngers
pinched between the movable part and the
panel. In places where small children are
present, make sure that an adult provides
supervision and guidance.
