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 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.

• 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.

• 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.

• 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.

• 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 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.

• 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 included tool.

ENGLISH

Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or data that is lost or destroyed.

Always turn the power off when the instrument is not in use.

Even when the power switch is in standby status, electricity is still flowing to the instrument at the minimum level. When you are not using the instrument for
a long time, make sure you unplug the power cord from the wall AC outlet.

Features

■ GHS (Graded Hammer Standard) keyboard

This Yamaha digital piano features a special “GHS (Graded Hammer Standard) keyboard with matte black
keytops.”

The GHS keyboard offers natural grand-piano type playability by simulating the heavier touch of the low range
and the lighter touch of the high range across the keyboard.

The matte black keytops enhance the piano’s luxurious and graceful appearance.

■ AWM Stereo Sampling

This digital piano sounds much closer to a true acoustic piano. Two of the piano Voices, “Grand Piano 1” and
“Grand Piano 2,” feature totally samples recorded from a concert grand piano. The “Electric Piano” Voice
features multiple samples for different velocities (Dynamic Sampling); that is, different samples are used
depending on how fast or strong you strike the keys.

Using the Pedals

When you press the damper
pedal here, the notes you play
before you release the pedal
sustain longer.

When you press the sostenuto
pedal here while holding the
note, the note will sustain as
long as you hold the pedal.

Damper (Right) pedal

The damper pedal functions in the same way as a
damper pedal on an acoustic piano. When the damper
pedal is pressed, notes sustain longer. Releasing the
pedal immediately stops (damps) any sustained notes.

Sostenuto (Center) pedal

If you play a note or chord on the keyboard and press
the sostenuto pedal while the note(s) are held, those
notes will sustain as long as you hold the pedal (as if the
damper pedal had been pressed) but all subsequently
played notes will not be sustained. This makes it
possible to sustain a chord, for example, while other
notes are played “staccato.”

The Voice assigned to the lower key is designated as Voice 1, and the Voice
assigned to the higher key is designated as Voice 2.

You can make the following settings for Voices 1 and 2 in Dual mode:

Setting the octave

You can shift the pitch up and down in octave steps for Voice 1 and Voice 2
independently.

Depending on which Voices you combine in Dual mode, the combination may
sound better if one of the Voices is shifted up or down an octave.

While holding down the [PIANO/VOICE] button, press one of the C5–F5 keys.

Setting the balance

You can adjust the volume balance between two Voices. For example, you can set
one Voice as the main Voice with a louder setting, and make the other Voice softer.

While holding down the [PIANO/VOICE] button, press one of the F
setting of “0” produces an equal balance between the two Dual mode Voices.

Settings below “0” increase the volume of Voice 2 in relation to Voice 1, and settings
above “0” increase the volume of Voice 1 in relation to Voice 2.

Transposition

Your digital piano’s Transpose function makes it possible to shift the pitch of the entire keyboard up or down in semitone
intervals up to a maximum of six semitones, and lets you easily match the pitch of the keyboard to the range of a singer or
other instruments.

For example, if you set the transposition amount to “5,” playing key C produces pitch F. In this way, you can play a song as
though it were in C major, and this instrument will transpose it to F major.

About MIDI

MIDI (Musical Instrument Digital Interface) is a global format standard for performance data transmission and reception
between electronic musical instruments.

Connecting musical instruments that support MIDI via MIDI cables enables you to transfer performance and setting data
between multiple musical instruments. Using MIDI, you can also achieve more advanced performances than using just a
single musical instrument.

MIDI data that can be
transmitted or received varies
depending on the type of MIDI
devices. Please check the
“MIDI Implementation Chart”
on the web (please refer to
“MIDI Reference” on page 6)
to find out what MIDI data and
commands your devices can
transmit or receive.

You need a dedicated MIDI
cable (optional) to make a
MIDI connection. MIDI cables
are available at most musical
instrument stores.

MIDI Applications

MIDI functions enable you to transfer performance data between MIDI devices, load song data from a connected computer
to your instrument, and transmit and save user song data to a computer.

Transferring performance data to and from another MIDI device

received will not affect this
instrument’s panel settings or
the notes you play on the
keyboard.

When MIDI receive channel is set to ALL:

A “Multi-timbre” Receive mode is available. In this mode, this instrument receives
different parts from the connected MIDI device on any or all 16 MIDI channels and
plays multi-channel song data.

Data for the demo song,
50 piano preset songs and
user song cannot be
transmitted via MIDI.

When MIDI receive channel is set to 1+2:

A “1+2” Receive mode is available. It allows simultaneous reception on channels 1
and 2 only, enabling this instrument to play 1 and 2 channel song data received from a
music computer or sequencer.

Local Control On/Off

“Local Control” refers to the fact that, normally, the keyboard of this digital piano controls its internal tone generator,
allowing the internal Voices to be played directly from the keyboard. This status is called “Local Control On,” since the
internal tone generator is controlled locally by its own keyboard.

Local control can be turned Off, however, so that the keyboard of this digital piano does not play the internal Voices, but the
appropriate MIDI information is still transmitted via the MIDI [OUT] connector when notes are played on the keyboard. At
the same time, the internal tone generator responds to MIDI information received via the MIDI [IN] connector.

While holding down the [DEMO/SONG] and [PIANO/VOICE] buttons
simultaneously, press the C6 key.

Pressing the C6 key repeatedly toggles between Local Control On and Off.
