Introduction
Setting Up
Be sure to do the following operations BEFORE turning on the power.
Although the instrument will run either from an optional 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.
Using an AC Power Adaptor
1 Make sure that the [ ] (Standby/On) switch of
the instrument is off (the power indicator located to
the left of the switch is off).
2 Connect the AC adaptor to the power supply jack.
3 Plug the AC adaptor into an AC outlet.
Using Batteries
1 Open the battery compartment cover located on the
instrument’s bottom panel.
2 Insert six new alkaline batteries, being careful to
follow the polarity markings on the side of the
compartment.
3 Replace the compartment cover, making sure that it
locks firmly in place.
For battery operation, the instrument requires six 1.5V
“AA” size, LR6 or equivalent batteries. (Alkaline bat-
teries are recommended.) When battery power
becomes too low for proper operation, the volume
may be reduced, the sound may be distorted, and other
problems may occur. When this happens, make sure to
replace all batteries, following the precautions listed
below.
Power Requirements
• Use the specified adaptor (page 22). The use of other
adaptors may result in irreparable damage to both the
adaptor and the instrument.
• Unplug the AC Power Adaptor when not using the
instrument, or during electrical storms.
• Never connect or disconnect the AC power adaptor when the power is on
and the batteries are installed. Doing so will turn the power off.

NOTE
• Make sure to install the batteries with the proper orienta-
tion, maintaining the correct polarity (as shown). Incorrect
battery installation may result in heat, fire and/or leaking of
corrosive chemicals.
• When the batteries run down, replace them with a com-
plete set of six new batteries. NEVER mix old and new bat-
teries. Do not use different kinds of batteries (e.g. alkaline
and manganese) at the same time.
• If the instrument is not to be used for a long time, remove
the batteries in order to prevent possible fluid leakage and
damage to the instrument.

Make sure to properly connect all external devices you are using (as shown below)
BEFORE turning the power on.
A pair of stereo headphones with a 1/4" stereo phone
plug can be plugged in the PHONES/OUTPUT jack
for convenient monitoring. The speakers are automati-
cally shut off when a plug is inserted into this jack.
The PHONES/OUTPUT jack also functions as an
external output. You can connect the PHONES/OUT-
PUT jack to a keyboard amplifier, stereo system,
mixer, tape recorder, or other line-level audio device
to send the instrument’s output signal to that device.
The SUSTAIN jack is for connecting the Footswitch or
foot pedal. The pedal functions in the same way as a
damper pedal on an acoustic piano. Connect an optional
footswitch FC4/FC5 to this jack and press the pedal to
sustain the sound. An optional FC3 Foot Pedal can also
be connected to this jack. If you connect an optional
FC3 Foot Pedal, the half pedal function* can be used.
* Half pedal function
If you are playing the piano with sustain but want to make the sound
between notes clearer, slightly release your foot from the pedal,
keeping the pedal down in half position or less.
Turn down the volume by turning the [MASTER
VOLUME] dial to the MIN position and press the
[ ] (Standby/On) switch to turn on the power. Press
the [ ] (Standby/On) switch again for a second to
turn the power to standby.
While playing the keyboard, adjust the volume level
by using the [MASTER VOLUME] dial.
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 30 minutes.
The Auto Power Off function can be set to on or off;
see page 18.
The instrument includes a music rest that can be
attached to the instrument by inserting it into the slot
at the top of the control panel.
Connecting Headphones or an Audio
Device (PHONES/OUTPUT Jack)
• Avoid listening with the headphones at high volume for
long periods of time; doing so may not only result in ear
fatigue, it may be damaging to your hearing.
• To prevent damage to the speakers, set the volume of the
external devices at the minimum setting before connecting
them. Failure to observe these cautions may result in elec-
tric shock or equipment damage. Also, be sure to set the
volumes of all devices at their minimum levels and gradu-
ally raise the volume controls while playing the instrument
to set the desired listening level.

The Transpose function makes it possible to shift the pitch of the entire keyboard up or down in semitone intervals to
facilitate playing in difficult key signatures, and to let 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 a C key actually pro-
duces a pitch of F. In this way, you can play a song as though it were in C major, and the instrument will transpose it
to the key of F.
Setting the amount of transposition
While holding down the [DEMO] button, press and hold the [METRONOME
ON/OFF] button, then press one of the F#2 – F#3 keys to set the desired
amount of transposition.
Setting range:
F#2 (-6 semitones) – C3 (normal pitch) –
F#3 (+6 semitones)
To transpose the pitch down (in semitone steps)
While holding down the [DEMO] button, press and hold the [METRONOME ON/
OFF] button, then press any key between F#2 and B2.
To transpose the pitch up (in semitone steps)
While holding down the [DEMO] button, press and hold the [METRONOME ON/
OFF] button, then press any key between C#3 and F#3.
To restore the normal pitch
While holding down the [DEMO] button, press and hold the [METRONOME ON/
OFF] button, then press the C3 key.
You can fine tune the pitch of the entire instrument. This function is useful when you play the instrument along
with other instruments or CD music.
Setting the Pitch
Hz (Hertz):
This unit of measurement refers to the fre-
quency of a sound and represents the
number of times a sound wave vibrates in
a second.
Setting range: 427.0 – 453.0 Hz
Default setting: A3 = 440Hz.
To lower or raise the pitch (in steps of roughly 1.0 Hz):
While holding down the [DEMO] button, press and hold the [METRONOME ON/
OFF] button, then press G3 (to lower) or B3 (to raise).
To lower or raise the pitch (in steps of roughly 0.2 Hz):
While holding down the [DEMO] button, press and hold the [METRONOME ON/
OFF] button, then press G#3 (to lower) or A#3 (to raise).
To restore standard pitch:
While holding down the [DEMO] button, press and hold the [METRONOME ON/
OFF] button, then press C3.

Connecting MIDI Instruments
The instrument features MIDI IN/OUT terminals, allowing you to connect the instrument to other instruments and
devices—including computers—and take advantage of the various performance and recording capabilities in
MIDI applications.
Since MIDI data that can be transmitted or
received varies depending on the type of
MIDI device, check the chapter “MIDI data
format” on page 4 in “MIDI Reference” to
find out what MIDI data and commands
your devices can transmit or receive.
MIDI [IN] [OUT] terminals
Use MIDI cables to connect external MIDI devices to
these connectors.
About MIDI
MIDI (Musical Instrument Digital Interface) is a standard format for data transmis-
sion/ reception. It enables the transmission of performance data and commands
between MIDI devices and personal computers. Using MIDI, you can control a con-
nected MIDI device from the instrument, or control the instrument from a con-
nected MIDI device or computer.
MIDI functions enable you to transmit performance data between MIDI devices.
You cannot transmit the Voice Demo
Songs and the Piano Preset Songs from
the instrument to another MIDI device.
For MIDI connections, use a standard
(optional) MIDI cable, available at most
musical instrument stores.
When the instrument is used as a tone
module, performance data with Voices
that are not found on the instrument will
not be played correctly.
Transmitting performance data to and from another MIDI device
Transmitting performance data to and from a computer
You must install an appropriate software
application on the computer to be able to
transmit performance data between the
instrument and a computer.
Connecting the USB port on the computer to the instrument via an
optional USB-MIDI interface (such as the Yamaha UX16)
Use a USB-MIDI interface device to connect the USB port on your computer
to the instrument’s MIDI terminals. You must install the USB-MIDI interface
(such as the UX16) driver. For more information, refer to the user’s manual
that came with the USB-MIDI interface device.
