PRECAUTIONS

Please read the following instructions carefully before using your vibes.

● Installation Location

Use or storage in the following locations may cause
damage, even when packaged.

• In direct sunlight, such as near a window, or in a
closed vehicle in daytime.

• Near heating devices or in other locations subject
to excessive heat.

• In excessively cold environment.

• In places with excessive humidity or dust.

• Locations subject to vibrations.

The driver and the controller, in particular, must be
protected from high humidity to avoid corrosion and
short circuit.

● Do Not Use Outdoors

Avoid using the instrument outdoors. Avoid exposure
to rain or moisture.

● Power Supply

Make sure to use the supplied AC adapter. Use of
different adapters may cause damage not covered by
the warranty.

● Handling

• Never place an object on or lean against the instru­ment, as this may cause damage to the tone bars
and frame parts or topple the instrument, which is
extremely dangerous.

• 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.

• Never try to disassemble the controller or driver, as
this may result in severe damage.

● Moving and Transporting the Instrument

• Move the instrument carefully to avoid shocks. Be­fore moving the instrument, make sure that the AC
adapter is disconnected 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 location make sure to fully disassemble it, taking
care to pack each component properly. Disassembly
steps are in the opposite order of assembly.

● When Not in Use

• Make sure to turn off the power switch and discon­nect the AC adapter from the outlet.

• Always engage the caster brakes.

● Maintenance

The tone bars should be polished from time to time
using a soft and dry cloth or silicone cloth. Stains that
cannot be removed 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.

● Keep This Manual for Future Reference

After reading, make sure to keep the manual in a safe
place.

Assembly Cautions

• 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 func­tionality of the instrument or cause noise.

• Make sure to adjust the wire clip positions
after assembly. (YV-3910/3710/3700: P. 17)

• Height adjustment of the striking surface (YV­3910/3710/3700: P. 18, YV-2700/2700G/
1600A/520: P 25) should be performed by AT
LEAST 2 PERSONS.

• After final adjustment of the legs the fixing
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.

■ Dividable Parts and Collapsible Parts (YV-3910/3710 only)

The YV-3910’s/YV-3710’s large parts are designed to either divide or collapse. When the instrument is
broken down, its compact size makes it easy to transport and storage requires a minimum amount of space.

● Rails

The rails fold in from the center.

● Pedal Stay

The pedal stay divides into left and right sections and the pedal itself.
Loosen the 2 wing nuts and remove the stays from the pedal attachment.

Loosen

● Sustain Damper

The sustain damper divides into 2 sections.
Loosen the bolt and separate left and right sections.

Loosen

● Resonators

Both resonators divide into two sections.
Loosen both bolts and separate left and right sections.

* When assembling the resonators, make sure that the

pin and notch are properly aligned.

10-2 Wire Clip Adjustment

For shipment the wire clip is initially set at a low position for packing reasons. For
normal use this clip should be adjusted as follows: With the pedal released loosen the
fixing bolt of the wire clip, shift the clip up until distance A in the illustration below is
1/16" to 1/8" (1 to 3 mm), and tighten the wing bold in this position.
The clip also allows setting the instrument to "half sustain damper" (slight continuous
damper effect) or "open damper"* by changing its position accordingly.
* To set to "open damper" depress the damper pedal fully to keep the damper open,

and set the wire clip to the highest position to lock the damper.

To adjust the height of the tone bars, first remove the synchro belt, driver, controller,
tone bars, and resonators in the reverse order of steps
loosen the center rod fixing bolts.
Loosen the slide leg fixing bolts on the high and low sound sides, while supporting the
frame ends by hand.
Lift the frame ends to the desired height and then securely tighten each fixing bolt,
aligning it with the corresponding notch of the slide leg. Bolt and notch are aligned
when the next higher notch is flush with the upper leg flange.

■ PAUSE MEMORY FUNCTION SETTING (YV-3910/3710/3700 only)

The YV-3910, YV-3710 and YV-3700 are equipped with a PAUSE MEMORY FUNCTION which
stops the fan always in exactly the same position when it is turned off (no vibrato applied).
After connection to an AC outlet, set the PAUSE MEMORY to the desired fan stop position as
follows:

z Turn the controller power ON.
x Press the START/STOP button once to start the fan, and

then press the START/STOP button once again to stop
the fan.

c Remove the synchro belt by sliding it off the fan side

13 Adjust the pedal stroke. (Refer to YV-3910/3710/3700 assembly step 10-1 on page 17.)

14 After assembly, confirm that each bolt and screw is tightened securely.

15 Height adjustment should always be performed by at least 2 persons.

To adjust the height of the tone bars, first remove the round belt (fan belt), driver, controller and tone
bars*, and loosen the center rod fixing bolts. (* To remove the tone bars, disengage the springs on the
low sound side, and then unhook the string from the post.)
Support both frame ends by hand (do not touch the metal parts shown in the illustration), and loosen
the slide leg fixing bolts.

Frame

Do not touch !

Lift the frame ends to the desired height and then securely tighten each slide leg fixing bolt, aligning
it with the corresponding notch of the slide leg. Bolt and notch are aligned when the next higher notch
is flush with the upper leg flange. (Refer to step

When a slide leg fixing bolt is tightened in between two
notches, there is a danger of the slide leg slipping.
Always make sure that the slide legs are held securely.

16 This completes the assembly of the instrument.

To play, connect the supplied AC adapter to the DC 12V IN jack of the controller. (Refer to YV-3700
assembly procedure, "Power Supply", on page 19.)

For height adjustment, make
sure to support the instrument
by the wooden frame. Do not
touch the metal parts.
