Power Outlet

Your Digital Piano runs on standard household power. Be
sure to turn off power whenever you are not using the Digital
Piano.

■ Using an AC Adaptor

Use only the AC adaptor (JEITA Standard, with unified
polarity plug) that comes with this Digital Piano. Use of a
different type of AC adaptor can cause malfunction.

Specified AC Adaptor:
AD-A12150LW

• Use the supplied power cord to connect the AC adaptor.

Bottom

• Never connect the AC adaptor that comes with this
Digital Piano to any other device besides this Digital
Piano. Doing so creates the risk of malfunction.

• Make sure the Digital Piano is turned off before
plugging in or unplugging the AC adaptor.

• The AC adaptor will become warm to the touch after
very long use. This is normal and does not indicate
malfunction.

• Never try to use the supplied power cord with any
other device.

• Place the AC adaptor on the floor with its label
surface pointed downwards. The AC adaptor
becomes more prone to electromagnetic wave
generation if the label surface is in a different
position.

Turning Power On or Off

■ To turn on power

Press the P (Power) button. Power up takes about five
seconds.

■ To turn off power

Hold down the P (Power) button until the power lamp goes
out.

Front

• Pressing the P (Power) button to turn off power

actually puts the Digital Piano into a standby state
(minute current continues to flow). If you do not plan
to use the Digital Piano for a long time or if there is a
lightning storm in your area, unplug the AC adaptor
from the power outlet.

■ Auto Power Off

Power turns off automatically after four hours of non-use.
To disable Auto Power Off, turn on power by holding down
the FUNCTION button and pressing P (Power).

Adjusting Volume

Use the VOLUME knob to adjust the volume of speaker and
headphone output.

Changing the Tuning

The factory tuning (A4=440.0Hz) can be change in 0.1 Hz
steps.

1.

Hold down the FUNCTION button and use the A­tuning keys (+, –).

• Tuning is raised or lowered in 0.1 Hz steps.

• To toggle between the two settings below, hold
down the FUNCTION button and press the A-tuning
keyboard keys (+ and –) at the same time.

440.0 Hz (1 beep)

442.0 Hz (2 beeps)

Connecting Headphones

Connect headphones to the PHONES/OUTPUT jack.
Connecting headphones mutes speaker output, so you can
practice even late at night. To protect your hearing, do not
set the volume too high when using headphones.

Front

NOTE

• If the plug of the headphones does not match the
PHONES/OUTPUT jack, use a commercially available
adaptor plug.

Selecting a Tone with a Button

1.

Press the GRAND PIANO 1 button or GRAND
PIANO 2 button.

Selecting a Tone with a Keyboard
Key

Tone names are marked above the keys.

1.

Hold down the FUNCTION button and press the
desired tone key. (See the “Tone” area under
“Keyboard Keys Used for Configuring Settings”.)

• Some keys may have more than one tone assigned.
In this case, each press of the key cycles to the next
assigned tone. Which tone is selected by the key
press is indicated by beeps.

Example: Cycling through MODERN, ROCK, and

JAZZ settings
MODERN: (1 beep)
ROCK: (2 beeps)
JAZZ: (3 beeps)

■ Bass Tone (BASS)

Pressing the BASS (LOWER) key to select a bass tone
selects a bass tone for the low end (left side) of the
keyboard only. The high end (right side) of the keyboard
retains the tone assigned to it before the bass tone was
selected.

sides have the same range. The left outer pedal is the left
side damper pedal, while the right outer pedal is the right
side damper pedal.

Changing the Octaves of the Keyboards

You can change the ranges of the left and right keyboards in
octave units from their initial default settings.

1.

Pressing the FUNCTION button and the GRAND
PIANO 1 button, press the C-key you want as
middle C (C4) of the left keyboard. Keep the
FUNCTION button and the GRAND PIANO 1
button depressed as you advance to step 2.

Example: Pressing the leftmost C key configures the

keyboards below.

2.

With the FUNCTION button and the GRAND
PIANO 1 button still depressed, press the C-key
you want as middle C (C4) of the right keyboard.

2/4USER’S GUIDE

Troubleshooting

If this happens: Do this:

No sound is produced when I
press a keyboard key.

The pitch of the Digital Piano
is off.

Nothing happens when I press
a pedal.

Tones and/or effects sound
strange. Turning power off and
then back on again does not
eliminate the problem.
Example: No change in

intensity when key press
pressure (touch) is changed

A tone’s quality and volume
sounds slightly different
depending where it is played
on the keyboard.

When I press a button, the
note that is sounding cuts out
momentarily or there is a
slight change in how effects
are applied.

I need to reset all Digital Piano
data and settings to their
initial defaults.

I need to reset a specific
setting to its initial default.

1. Rotate the VOLUME knob more towards “MAX”.

2. Disconnect whatever is connected to the PHONES/OUTPUT jack.

3. Turn on the Local Control setting. For details, refer to the “User’s Guide (Full)”.

1. Change the transpose setting to “0”. Or turn power off and then back on.

2. Change the tuning setting to 440.0 Hz. Or turn power off and then back on.

3. Change the octave shift setting to “0”. For details, refer to the “User’s Guide (Full)”.

4. Change the temperament setting to “00: Equal”.
Check the orientation of the pedal unit plug and makes sure it is inserted as far as it goes.

For the correct plug orientation, see “To connect the cables” under “Assembling the
Stand” of page 4/4 of these instructions.

Turn off Auto Resume, and then turn power off and then back on again. For details, refer
to the “User’s Guide (Full)”.

This is an unavoidable result of the digital sampling process,* and does not indicate
malfunction.

* Multiple digital samples are taken for the low range, middle range, and high range of

the original musical instrument. There may be a very slight difference in tonal quality
and volume between sample ranges.

This happens while multiple parts are sounding at the same time while using layer, using
the Duet Mode, playing back a built-in tune, recording, etc. Pressing a button when one of
these conditions exists causes the effect setting that is built into the tone to change
automatically, which causes notes to cut out momentarily or a slight change in how
effects are applied. It does not indicate malfunction

Hold down the FUNCTION, MIDI REC and GRAND PIANO 2 buttons, and press the
power button to turn on power.

Hold down the FUNCTION button and press the + and – keyboard keys of the setting at
the same time.
