Caution
Do not use the instrument in locations with poor ven-
tilation.
Never pull on the cord when disconnecting the AC
adaptor from the outlet. Always hold the AC adaptor
when connecting or disconnecting the power.
Always disconnect the AC adaptor from the outlet
when the instrument is not used for any extended pe-
riod of time.
Always use the supplied power adaptor. The use of
any other power adaptor may cause damage.
Never place your hands or feet underneath the pedal.
Doing so can result in pinched hands or feet.
Never touch the rotating fans. Doing so can result in
pinched fi ngers, etc.
Never use the mallets for anything other than playing
the instrument. Doing so can result in injury or acci-
dents. Do not allow children to use the mallets in any
way that may pose a danger to themselves or others.
Lock the stoppers on the casters when the instrument
is not in use.
Please read the following instructions carefully before using your vibes.
● Do Not Use Outdoors
Avoid using the instrument outdoors. Avoid exposure to rain or
moisture.
● Handling
• Do not use hard orchestra bell mallets or other hard objects
on your vibes. The resulting dents or scratches in the tone
bars could impair the sound.
• Rough handling of the controller and/or the driver may cause
damage to the internal circuitry.
● Moving and Transporting the Instrument
• Move the instrument carefully to avoid shocks. Before moving
the instrument, make sure that the AC adapter is disconnect-
ed and the caster brakes are released. Also make sure to lift
the instrument slightly when moving over rough surfaces.
• When the instrument must be transported to a different loca-
tion make sure to fully disassemble it, taking care to pack
each component properly. Disassembly steps are in the op-
posite order of assembly.
● Maintenance
The tone bars should be polished from time to time using a
soft and dry cloth or silicone cloth. Stains that cannot be re-
moved with a dry cloth may be wiped off using a small amount
of ethyl alcohol. Never use thinner or benzene or a wet cloth
for cleaning purposes.

PRECAUTIONS
● Keep This Manual for Future Reference
After reading, make sure to keep the manual in a safe place.
• When assembling/disassembling the instrument, make sure
to follow the procedure outlined in this manual. Assembly in
the wrong order may impair the performance and functional-
ity of the instrument or cause noise.
• Make sure to adjust the wire clip positions after assembly.
(YV-3910/3710/3700: P. 23)
• Height adjustment of the str iking surface (YV-
3910/3710/3700: P. 24, YV-2700/2700G/1600A/520: P. 31)
should be performed by AT LEAST 2 PERSONS.
• After fi nal adjustment of the legs the fi xing screws must
be tightened securely to prevent loosening. Looseness
may cause the instrument to shift during performance and
can also cause noise and other problems. Retighten the
screws from time to time.
When adjusting the playing surface height (described
on page 29), make sure that the procedure is per-
formed by at least two persons. Attempting to adjust
the height alone can result in the instrument over-
turning and create a danger.
Never touch the areas shown below when adjusting
the height. Doing so can result in pinched hands.
Make sure to hold the side frame when making
height adjustments.
Side Frame
Tighten bolts securely after determining the desired
height. Using the instrument with loose bolts can
result in the instrument collapsing, noise, or other
troubles. Tighten the bolts occasionally.
