Setting Up
Be sure to do the following operations BEFORE turning on the power.
Introduction
Power Requirements
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).
WARNING
• Use the specified adaptor (page 22). The use of other
adaptors may result in irreparable damage to both the
adaptor and the instrument.
2 Connect the AC adaptor to the power supply jack.
3 Plug the AC adaptor into an AC outlet.
CAUTION
• Unplug the AC Power Adaptor when not using the
instrument, or during electrical storms.

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.
NOTE
• 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.
For battery operation, the instrument requires six 1.5V
“AA” size, LR6 or equivalent batteries. (Alkaline batteries 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.
WARNING
• Make sure to install the batteries with the proper orientation, 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 complete set of six new batteries. NEVER mix old and new batteries. 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.
NP-31/NP-11 Owner’s Manual

The PHONES/OUTPUT jack also functions as an
external output. You can connect the PHONES/OUTPUT 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.
CAUTION
• 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.
CAUTION
• 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 electric shock or equipment damage. Also, be sure to set the
volumes of all devices at their minimum levels and gradually raise the volume controls while playing the instrument
to set the desired listening level.
Connecting a Footswitch or a Foot
Pedal (SUSTAIN Jack)
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.

Transposing the Pitch
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 produces 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.

between MIDI devices and personal computers. Using MIDI, you can control a connected MIDI device from the instrument, or control the instrument from a connected MIDI device or computer.
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 Capabilities
MIDI functions enable you to transmit performance data between MIDI devices.

Troubleshooting
Problem
The instrument does not turn on.
Possible Cause and Solution
The instrument has not been plugged in properly. Securely insert the female
plug into the jack on the instrument, and the male plug into a proper AC outlet
(page 7).
The batteries are low or dead. Replace all six batteries with completely new
alkaline ones, or use the optional AC adaptor.
Noise is heard from the speakers or
headphones.
The noise may be due to interference caused by the use of a mobile phone in
close proximity to the instrument. Turn off the mobile phone, or use it further
away from the instrument.
The batteries are low or dead. Replace all six batteries with completely new
alkaline ones, or use the optional AC adaptor.
The Master Volume is set too low; set it to an appropriate level using the [MASTER VOLUME] dial.
The overall volume is low, or no sound
is heard.
Make sure a pair of headphones is not connected to the headphones jack
(page 8).
Make sure that Local Control (page 20) is ON.
The batteries are low or dead. Replace all six batteries with completely new
alkaline ones, or use the optional AC adaptor.
The sound is distorted.
If you are using manganese batteries with the instrument, try replacing them
with a set of new alkaline batteries. Alternately, you could use the AC adaptor
instead, or try turning down the volume.
The sustain pedal has no effect.
The pedal cable/plug may not be properly connected. Make sure to securely
insert the pedal plug into the SUSTAIN jack (page 8).
The pitch and/or tone of the piano
Voices in certain ranges do not sound
right.
The piano Voices attempt to precisely simulate actual piano sounds. However,
as a result of sampling algorithms, overtones in some ranges may sound exaggerated, producing a somewhat different pitch or tone.
Power suddenly and unexpectedly
turns off.
This is normal and the Auto Power Off function may have been activated. If you
need to disable the Auto Power Off function, select “Off” in the function settings
(page 18).
