WARNING-
When using any electrical or electronic prod-
uct, basic precautions should always be followed. These precau-
tions include, but are not limited to, the following:
1. Read all Safety Instructions, Installation Instructions,
Special Message Section items, and any Assembly Instructions
found in this manual BEFORE making any connections, includ-
ing connection to the main supply.
2. Do not attempt to service this product beyond that
described in the user-maintenance instructions. All other servic-
ing should be referred to qualified service personnel.
3. Main Power Supply Verification: Yamaha products are
manufactured specifically for the supply voltage in the area
where they are to be sold. If you should move, or if any doubt
exists about the supply voltage in your area, please contact your
dealer for supply voltage verification and (if applicable) instruc-
tions. The required supply voltage is printed on the name plate.
For name plate location, please refer to the graphic found in the
Special Message Section of this manual.
4. DANGER-Grounding Instructions: This product must
be grounded and therefore has been equipped with a three pin
attachment plug. If this product should malfunction, the ground
pin provides a path of low resistance for electrical current,
reducing the risk of electrical shock. If your wall socket will not
accommodate this type plug, contact an electrician to have the
outlet replaced in accordance with local electrical codes. Do
NOT modify the plug or change the plug to a different type!
5. WARNING: Do not place this product or any other
objects on the power cord or place it in a position where anyone
could walk on, trip over, or roll anything over power or connect-
ing cords of any kind. The use of an extension cord is not
recommended! If you must use an extension cord, the minimum
wire size for a 25' cord (or less) is 18 AWG. NOTE: The smaller
the AWG number, the larger the current handling capacity. For
longer extension cords, consult a local electrician.
6. Ventilation: Electronic products, unless specifically
designed for enclosed installations, should be placed in locations
that do not interfere with proper ventilation. If instructions for
enclosed installations are not provided, it must be assumed that
unobstructed ventilation is required.
7. Temperature considerations: Electronic products should
be installed in locations that do not seriously contribute to their
operating temperature. Placement of this product close to heat
sources such as; radiators, heat registers etc., should be avoided.
8. This product was NOT designed for use in wet/damp
locations and should not be used near water or exposed to rain.
Examples of wet /damp locations are; near a swimming pool,
spa, tub, sink, or wet basement.
9. This product should be used only with the components
supplied or; a cart ,rack, or stand that is recommended by the
manufacturer. If a cart, rack, or stand is used, please observe all
safety markings and instructions that accompany the accessory
product.
10.The power supply cord (plug) should be disconnected
from the outlet when electronic products are to be left unused
for extended periods of time. Cords should also be disconnected
when there is a high probability of lightening and/or electrical
storm activity.
11.Care should be taken that objects do not fall and liquids
are not spilled into the enclosure through any openings that may
exist.
12.Electrical/electronic products should be serviced by a
qualified service person when:
a. The power supply cord has been damaged; or
b. Objects have fallen, been inserted, or liquids have been
spilled into the enclosure through openings; or
c. The product has been exposed to rain; or
d. The product does not operate, exhibits a marked change
in performance; or
e. The product has been dropped, or the enclosure of the
product has been damaged.
13.This product, either alone or in combination with an
amplifier and headphones or speaker/s, may be capable of
producing sound levels that could cause permanent hearing loss.
DO NOT operate for a long period of time at a high volume
level or at a level that is uncomfortable. If you experience any
hearing loss or ringing in the ears, you should consult an audi-
ologist.
IMPORTANT: The louder the sound, the shorter the time
period before damage occurs.
14.Some Yamaha products may have benches and/or acces-
sory mounting fixtures that are either supplied as a part of the
product or as optional accessories. Some of these items are
designed to be dealer assembled or installed. Please make sure
that benches are stable and any optional fixtures (where appli-
cable) are well secured BEFORE using. Benches supplied by
Yamaha are designed for seating only. No other uses are recom-
mended.

About the Backup Battery
A backup battery (lithium battery) is used to keep internal data (settings) from being lost, even when
the power cord is unplugged. Internal data will be lost when battery power is depleted, so it is recom-
mended that data be stored to an external data recorder such as the Y amaha MIDI Data Filer MDF3
(→ page 24), or keep records of settings in memo form. The average battery life span is about 3
years. When replacement becomes necessary contact the music store where the unit was pur-
chased, or a qualified service representative, to perform the replacement.
• Do not attempt to replace the backup battery by yourself.
• Keep the backup battery out of reach of children.
•“E5” appears in the display when the battery becomes depleted. Internal data may be lost.
• Data may be lost if the unit is improperly handled or if repairs are performed.
Precautions
• Avoid using the DG-Stomp in the following locations to prevent possible damage:
• In direct sunlight or next to heating equipment.
• In extremely cold or hot locations.
• Locations exposed to high humidity or excessive dust.
• Locations subject to strong shocks or vibration.
• Before making any connections, make sure that the power is switched OFF on the DG-Stomp
and any external devices.
• To protect speakers from possible damage, always set the OUTPUT knob to “0” before switching
the power ON/OFF.
• When connecting a speaker to this unit, make sure that the power is switched OFF first.
• Do not apply excessive force to the switches, knobs and controls.
• The DG-Stomp is a precision device. Handle it with care and avoid dropping or jarring it.
• Operating temperatures will rise during use. Make sure the DG-Stomp is used in a well-ventilated
are.
• For safety, always remove the power adaptor from the AC wall outlet if there is any danger of
lightning striking in your area.
• Keep the DG-Stomp away from neon signs or fluorescent lighting to prevent noise pickup.
• To prevent damage and possibly electrical shock, never open the case and tamper with the
internal circuitry.
• Never use benzene, thinner or other volatile liquids for cleaning, as these chemicals may cause
damage or discoloration to the finish. Always use a dry, soft cloth to wipe off dust and dirt.
