About the Backup Battery
(DG series Guitar Amplifiers)
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
recommended that data be stored to an external data recorder
such as the Yamaha MIDI Data Filer MDF3 (
→ page. 12), 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 purchased, or a qualified ser-
vice representative, to perform the replacement.
• Do not attempt to replace the backup battery by yourself.
• Keep the backup battery out of reach of children.
• “ E6 ” 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.
● Avoid using your amplifier and speaker in the following locations
to prevent possible damage:
• In direct sunlight or next to heating equipment.
• 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 on
the amplifier and any external devices is switched OFF.
● To protect the speaker 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 to turn OFF
the power first.
● Do not apply excessive force to the switches and controls.
● Your Yamaha guitar amplifier is a precision musical instrument.
Handle it with care and avoid dropping or bumping it.
● Operating temperatures will rise during use. Make sure the
amplifier is used in a well-ventilated area. The DG130HA should
be placed in a position were there is at least 30 cm (12”)
clearance from the wall on the sides, top and back of the
amplifier.
● For safety, always remove the power plug from the AC wall
outlet if there is any danger of lightning striking in your area.

● Keep the amplifier 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.
