Handling caution
Using the bench (If included)
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 multiple-connector.
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.
• Read carefully the attached documentation explaining the assembly process.
Failure to assemble the instrument in the proper sequence might result in
damage to the instrument or even injury.
• (YDP-S54) Be sure to attach the anti-fall brackets to the instrument, to ensure
stability. Failure to do so might result in damage to the instrument or even injury.
• Do not place the instrument in an unstable position where it might accidentally
fall over.
• When transporting or moving the instrument, always use two or more people.
Attempting to lift the instrument by yourself may damage your back, result in
other injury, or cause damage to the instrument itself.
• 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.
• Do not insert a finger or hand in any gaps on the key cover or instrument. Also
take care that the key cover does not pinch your finger.
• Never insert or drop paper, metallic, or other objects into the gaps on the key
cover, panel or keyboard. This could cause physical injury to you or others,
damage to the instrument or other property, or operational failure.
• (YDP-S54) Do not apply excessive force when closing the key cover. A key cover
equipped with the SOFT-CLOSE™ mechanism closes the cover slowly. Applying
excessive force to the key cover when closing it could damage the SOFTCLOSE™ mechanism, and possibly result in injury to your hands and fingers
caught under the closing key cover.
• 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.
• Do not place the bench in an unstable position where it might accidentally fall
over.
• Do not play carelessly with or stand on the bench. Using it as a tool or stepladder
or for any other purpose might result in accident or injury.
• Only one person should sit on the bench at a time, in order to prevent the
possibility of accident or injury.
• If the bench screws become loose due to extensive long-term use, tighten them
periodically using the specified tool in order to prevent the possibility of accident
or injury.
• Keep special watch over any small children so that they don’t fall off the rear of
the bench. Since the bench does not have a backrest, unsupervised use may
result in accident or injury.
• 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.

Auto Power Off Function
To prevent unnecessary power consumption, this
instrument features an Auto Power Off function
that automatically turns the power off if the
instrument is not operated for approximately
30 minutes.
Default setting: Enabled
Disabling Auto Power Off (simple method)
Turn off the power of the instrument once.
While holding down the A-1 key (the lowest key),
press the [P] (Standby/On) switch to turn the
instrument on. The [REC] indicator flashes three
times, indicating the Auto Power Off function has
been disabled.
Switching the Auto Power Off Function
(Enable/Disable)
While holding down [DEMO/SONG] and
[PIANO/VOICE] simultaneously, press the A#0
key to enable the Auto Power Off function or the
A0 key to disable it.
Using Headphones
Since this instrument is
equipped with two
[PHONES] jacks, you
can connect two sets of
standard stereo
headphones. If you are
using only one set of
headphones, insert a plug
into either jack, which
automatically shuts off
the speakers according to
the default setting.
CAUTION
Do not use headphones at a high volume for an extended
period of time; doing so may cause hearing loss.
Speaker On/Off setting
You can set whether the sound of this instrument is
always output from its built-in speaker or not.
While holding down [DEMO/SONG] and
[PIANO/VOICE] simultaneously, press one of the

The speaker will not sound.
The speaker will always sound regardless
of whether a set of headphones is
connected or not.
The speaker will sound only if headphones
are not connected. (This is the default
setting.)
Reproducing a natural sense of distance
(Stereophonic Optimizer)
The Stereophonic Optimizer gives you the feeling
of playing an actual acoustic piano — even though
you’re listening through headphones. Normally, the
sound comes out from headphones sounds very
close to your ears. However, this Stereophonic
Optimizer effect recreates a natural distance or the
sense of physical space between your ears and the
instrument, just as when playing an acoustic piano.
Default setting: On
While holding down [PIANO/VOICE], press the
F#3 key to turn the function on or the F3 key to
turn the function off.
