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 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 filter
between this unit and the electrical outlet.
• To prevent malfunction and equipment failure,
always make sure to turn off the power on all your
equipment before you make any connections.
• Although the LEDs are switched off when the
unit is turned 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 unit’s 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.
• With the factory settings, the GA-212/GA-112 will
automatically be switched off 4 hours after you stop
playing or operating the unit. If you don’t want the
unit to turn off automatically, set the “AUTO OFF”
switch to “OFF” as described on p. 6.
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.
• 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 paste stickers, decals, or the like to this
instrument. Peeling such matter off the instrument
may damage the exterior finish.
• 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
• 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. 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.
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 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 write down
the settings stored in the unit’s memory on paper.
• 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.
• 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.
• A small amount of heat will radiate from the unit
during normal operation.
• To avoid disturbing others nearby, try to keep the
unit’s volume at reasonable levels.
• 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 specified 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 specifications,
contact the manufacturer of the cable.

CAUTION
Place in a well ventilated location
The unit should be located so that its
location or position does not interfere with
its proper ventilation.
Grasp the plug when connecting or disconnecting
the power cord
Always grasp only the plug on the
power-supply cord when plugging into, or
unplugging from, an outlet or this unit.
Periodically clean the power cord’s plug
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.
CAUTION
Manage cables for safety
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.
Remove all casters if mobility presents danger
In every situation where the unexpected
movement of this unit could present a
danger (such as when it’s set up on a stage,
or when it’s being transported inside
a vehicle), make sure to remove all the
casters.
Avoid climbing on top of the unit, or placing heavy
objects on it
Never climb on top of, nor place heavy
objects on the unit.
Do not connect or disconnect the power cord with
wet hands
Never handle the power cord or its plugs
with wet hands when plugging into, or
unplugging from, an outlet or this unit.
CAUTION
Disconnect everything before moving the unit
Before moving the unit, disconnect the
power plug from the outlet, and pull out
all cords from external devices.
Unplug the power cord from the outlet before
cleaning
Before cleaning the unit, turn it off and
unplug the power cord from the outlet
(p. 6).
If there is a possibility of lightning strike, disconnect
the power cord from the outlet
Whenever you suspect the possibility of
lightning in your area, pull the plug on the
power cord out of the outlet.
Do not remove the speaker grille and speaker
Do not remove the speaker grille and
speaker by any means. Speaker not user
replaceable. Shock hazardous voltages and
currents are present inside the enclosure.
