CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you
or others, or damage to the instrument or other property. These precautions include, but are not
limited to, the following:
• Do not connect the instrument to an electrical outlet using a
multipleconnector. Doing so can result in lower sound quality, or
possibly cause overheating in the outlet.
• When removing the electric plug from the instrument or an outlet,
always hold the plug itself and not the cord. Pulling by the cord
can damage it.
• Remove the electric plug from the outlet when the instrument is
not to be used for extended periods of time, or during electrical
storms.
• Do not place the instrument in an unstable position where it might
accidentally fall over.
• Before moving the instrument, remove all connected cables, to
prevent damage to the cables or injury to anyone who might trip
over them.
• When setting up the product, make sure that the AC outlet you are
using is easily accessible. If some trouble or malfunction occurs,
immediately turn off the power switch and disconnect the plug
from the outlet. Even when the power switch is turned off,
electricity is still flowing to the product at the minimum level.
When you are not using the product for a long time, make sure to
unplug the power cord from the wall AC outlet.
• Use only the stand specified for the instrument. When attaching it,
use the provided screws only. Failure to do so could cause
damage to the internal components or result in the instrument
falling over.
• Before connecting the instrument to other electronic components,
turn off the power for all components. Before turning the power on
or off for all components, set all volume levels to minimum.
• Be sure to set the volumes of all components at their minimum
levels and gradually raise the volume controls while playing the
instrument to set the desired listening level.
• Do not insert a finger or hand in any gaps on the instrument.
• Never insert or drop paper, metallic, or other objects into the gaps
on the panel. This could cause physical injury to you or others,
damage to the instrument or other property, or operational failure.
• Do not rest your weight on, or place heavy objects on the
instrument, and do not use excessive force on the buttons,
switches or connectors.
• Do not use the instrument/device or headphones for a long period
of time at a high or uncomfortable volume level, since this can
cause permanent hearing loss. If you experience any hearing loss
or ringing in the ears, consult a physician.

Power Requirements
Although the instrument will run either from an AC
adaptor or batteries, Yamaha recommends use of an
AC adaptor whenever possible. An AC adaptor is
more environmentally friendly than batteries and
does not deplete resources.
Usingan AC Adaptor
Connect the AC adaptor in the order shown in the
illustration.
UsingBatteries
This instrument requires six “AA” size, Alkaline (LR6)/
Manganese (R6) batteries, or rechargeable nickel-
metal hydride batteries (rechargeable Ni-MH batter-
ies). The Alkaline batteries or rechargeable Ni-MH
batteries are recommended for this instrument, since
other types may result in poorer battery performance.
1Make sure that the power of the instrument is off.
2Open the battery compartment cover located on
the instrument’s bottom panel.
3Insert the six new batteries, being careful to follow
the polarity markings on the inside of the com-
partment.
4Replace the compartment cover, making sure that
it locks firmly in place.
Make sure to set the battery type correctly (page 13).
• Use the specified AC adaptor (page 85) only. Using the
wrong AC adaptor can result in damage to the instrument
or overheating.
• When using the AC adaptor with a removable plug, make
sure to keep the plug attached to the AC adaptor. Using the
plug alone can cause electric shock or fire.
• If the plug is accidentally removed from the AC adaptor,
slide it back in until it clicks into place, taking care to
avoid touching any internal metal parts. To avoid electric
shock, short circuit or damage, also be careful that there
is no dust between the AC adaptor and plug.
• When setting up the product, make sure that the AC outlet
you are using is easily accessible. If some trouble or mal-
function occurs, immediately turn the power off and dis-
connect the plug from the outlet.
• Follow the order shown above in reverse when disconnecting
the AC adaptor.

This instrument can apply various Effects as listed
below to the instrument’s sound.
DSP
The DSP (digital signal processor) is an effect in
which digital signal processing is applied to the
sound to change it.
When a Voice or Song that features a recommended
DSP processing is selected, the DSP effect is
applied to the Main Voice and Song part. DSP effect
has effect variations, called DSP types. Please refer
to page 82.
You can also turn the DSP on / off and change the
DSP type using the following procedure.
1Press the [DSP] button to turn on the DSP.
When the DSP is turned on, the DSP type (page
82) appropriate for the current panel setting is
automatically selected, but you can also select it
yourself.

ond. After a few seconds, the current DSP type
appears.

buttons to select the desired type.
4Play the keyboard.
5Press the [DSP] button again to turn off the DSP.
Changing the Touch Response of
the Keyboard
1Soft
Produces relatively high volume even with
light playing strength. Best for players with a
light touch who want to maintain a consis-
tent, relatively loud volume.
2Medium Produces a fairly “standard” keyboard
response.
3Hard
The keys must be played very strongly to
generate loud volume. This setting is best
for a wide dynamic range and optimum
expressive control of the sound, from pianis-
simo to fortissimo.
4Fixed All notes are produced at the same volume
no matter how hard the keyboard is played.
• When the Touch Response is [Fixed], the strength meter
is at fixed medium strength.

Articulation
Articulation is an effect that reproduces the sounds
of playing methods that are unique to specific acous-
tic instruments.
The Articulation effect is applied to the sound only
while holding down the [ARTICULATION] button. The
Articulation effect is enabled only for S.Art Lite
Voices (Super Articulation Lite Voices). The S.Art
Lite Voices are indicated by “***” in Voice List (page

[ARTICULATION] button, a harmonics sound is pro-
duced.
Example: Voice number 048 “S.Art Lite Distortion
Guitar”
If you press the [ARTICULATION] button, a scratch-
ing noise is produced.
When S.Art Lite Voices are selected, the appropriate
articulation effect is automatically selected.
When other Voices are selected, the modulation
effect is automatically selected.
1Press the [ARTICULATION] button while playing
the keyboard.
2Release the [ARTICULATION] button to turn
Articulation off.

Reverb
Adds the ambience of a club or concert hall to the
sound. Although the best-suited Reverb type is
called up by selecting a Song or Style, you can
select another one via Function number 020 (page
53). When you select “oFF,” the Reverb effect is
turned off. And you can also set the Reverb depth via
Function number 021 (page 53).
Chorus
Makes the Voice sound richer, warmer and more
spacious. Although the best-suited Chorus type is
called up by selecting a Song or Style, you can
select another one via Function number 022 (page
53). When you select “oFF,” the Chorus effect is
turned off. You can also set the Chorus depth for
Voices via Function numbers 007 (page 52), 011, 015
(page 53).
The Chorus depth cannot be applied to the Styles or
Songs.
Sustain
By turning on the Sustain parameter of Function
number 024 (page 53), you can add a fixed, auto-
matic sustain to the Main/Dual Voices played on the
keyboard. Or, you can produce a natural sustain as
desired with the footswitch (sold separately; page
14).
