Before using this unit, carefully read the sections entitled:
“USING THE UNIT SAFELY” and “IMPORTANT NOTES” (p. 2–
3; p. 5). These sections provide important information concerning
the proper operation of the unit. Additionally, in order to feel
assured that you have gained a good grasp of every feature
provided by your new unit, Owner’s manual should be read in its
entirety. The manual should be saved and kept on hand as a
convenient reference.
• Do not attempt to repair the unit, or replace
parts within it (except when this manual
provides specific instructions directing you
to do so). Refer all servicing to your retailer,
the nearest Roland Service Center, or an
authorized Roland distributor, as listed on
the “Information” page.

• Be sure to use only the AC adaptor
supplied with the unit. Also, make sure the
line voltage at the installation matches the
input voltage specified on the AC adaptor’s
body. Other AC adaptors may use a
different polarity, or be designed for a
different voltage, so their use could result
in damage, malfunction, or electric shock.
• Do not excessively twist or bend the power
cord, nor place heavy objects on it. Doing
so can damage the cord, producing severed
elements and short circuits. Damaged cords
are fire and shock hazards!
• Immediately turn the power off, remove
the AC adaptor from the outlet, and request
servicing by your retailer, the nearest
Roland Service Center, or an authorized
Roland distributor, as listed on the “Information” page when:
• The AC adaptor or the power-supply
cord has been damaged; or
• Objects have fallen into, or liquid has
been spilled onto the unit; or
• The unit has been exposed to rain (or
otherwise has become wet); or
• The unit does not appear to operate
normally or exhibits a marked change in
performance.
• In households with small children, an adult
should provide supervision until the child
is capable of following all the rules
essential for the safe operation of the unit.
• Do not force the unit’s power-supply cord
to share an outlet with an unreasonable
number of other devices. Be especially
careful when using extension cords—the
total power used by all devices you have
connected to the extension cord’s outlet
must never exceed the power rating
(watts/amperes) for the extension cord.
Excessive loads can cause the insulation on
the cord to heat up and eventually melt
through.
• Before using the unit in a foreign country,
consult with your retailer, the nearest
Roland Service Center, or an authorized
Roland distributor, as listed on the “Information” page.
• If used improperly, batteries may explode
or leak and cause damage or injury. In the
interest of safety, please read and observe
the following precautions (p. 14).
1
• Carefully follow the installation instruc-
tions for batteries, and make sure you
observe the correct polarity.
2
• Avoid using new batteries together with
used ones. In addition, avoid mixing
different types of batteries.
3
• Remove the batteries whenever the unit
is to remain unused for an extended
period of time.
5
• If a battery has leaked, use a soft piece of
cloth or paper towel to wipe all
remnants of the discharge from the
battery compartment. Then install new
batteries. To avoid inflammation of the
skin, make sure that none of the battery
discharge gets onto your hands or skin.
Exercise the utmost caution so that none
of the discharge gets near your eyes.
Immediately rinse the affected area with
running water if any of the discharge
has entered the eyes.
6
• Never keep batteries together with
metallic objects such as ballpoint pens,
necklaces, hairpins, etc.
• Used batteries must be disposed of in
compliance with whatever regulations for
their safe disposal that may be observed in
the region in which you live.
• All Program Change information can be transmitted using only the pedals and buttons.
• The GFC-50 can accept connection of two external expression pedals and two foot
switches. This allows you to control the connected MIDI instrument in real time with
Control Change messages.
• The GFC-50 employs a two-way Battery/AC power supply.
• During battery operation the Economy Mode can be used to effectively extend battery
life by about twice as long as usual. When the battery voltage is low, a warning
indicator will appear.
• A Cord Hook is provided to prevent the unit from being disconnected accidentally
during AC operation.

IMPORTANT NOTES
291a
In addition to the items listed under “USING THE UNIT SAFELY” on page 2, please read and
observe the following:
Power Supply:
Use of Batteries
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).
302
• The AC adaptor will begin to generate heat
after long hours of consecutive use. This is
normal, and is not a cause for concern.
303a
• The use of an AC adaptor is recommended as
the unit’s power consumption is relatively
high. Should you prefer to use batteries,
please use the alkaline type.
304a
• When installing or replacing batteries, always
turn off the power on this unit and disconnect
any other devices you may have connected.
This way, you can prevent malfunction and/
or damage to speakers or other devices.
307
• 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.
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 interference.
352
• This device may interfere with radio and
television reception. Do not use this device in
the vicinity of such receivers.
355
• To avoid possible breakdown, do not use the
unit in a wet area, such as an area exposed to
rain or other moisture.
Maintenance
401a
• 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.
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 unit’s buttons, sliders, or other controls;
and when using its jacks and connectors.
Rough handling can lead to malfunctions.
554
• Never strike or apply strong pressure to the
display.
556
• When connecting / disconnecting all cables,
