[Power] Switch
This turns the power on/o.
* With the factory settings, the LX-15’s power will
automatically be switched o 30 minutes after you
stop playing or operating the unit.
If the unit’s power has been turned o automatically, you can use the
[Power] switch to turn the unit back on again.
If you don’t want the power to turn o automatically, change the “Auto O”
setting to “O” as described on “Making the Power Automatically Turn O
After a Time (Auto O)” (p. 40).
* When turning the power on again, you must allow at least ve seconds after
power-o before you once again turn the power on.
If you fail to allow enough time, the Auto O function might not be reset,
preventing the power from turning on correctly.

Top Lid
By opening or closing the lid you can change the clarity of the
sound.
Damper Pedal
Use this pedal to sustain the sound. While this pedal is held down, notes will be sustained for an extended time even if you
release your ngers from the keyboard.
With the damper pedal on an acoustic piano, when you step on the pedal it will at rst oer only a slight amount of resistance,
but as you press down further it will start to feel much heavier. On the LX-15, this change in the feeling of resistance is
simulated.
On an acoustic piano, when you step on the damper pedal, you’ll rst hear the sound of the dampers releasing the strings. Then,
you should also be able to hear the sound of strings adjacent to the ones for the notes actually played resonate sympathetically,
resulting in a rich, resounding tone.
Additionally, when using half-pedaling techniques, the core of the sound disappears rapidly while a rich, spacious resonance
remains, producing a unique form of reverberation. On the LX-15, the unique, lingering tones produced by the half-pedaling
technique are reproduced in addition to released-string sounds (Damper Noise) and resonating sounds (Damper Resonance).
Sostenuto Pedal
The notes you are pressing when this pedal is depressed will be sustained.
Soft Pedal
This pedal is used to make the sound softer.
Playing with the soft pedal depressed produces a sound that is not as strong as when otherwise played with the equivalent
strength. This is the same function as the left pedal of an acoustic piano.
The softness of the tone can be varied subtly by the depth to which you press the pedal.

Headphone Hook
Whenever you are not using the
headphones, you can hang them on the

* Don’t hang anything other than headphones on
this hook, and don’t apply excessive force to it.
Doing so may damage the headphone hook.

NOTE
If you need to move the piano, make sure the lid is closed rst to prevent accidents.
Opening/Closing the Top Lid
Opening the lid will make the sound more sharply dened; closing the lid produces a more mellow sound.
NOTE
• The top lid must be opened or closed by an adult.
• Do not force the top lid backward; doing so will damage it.
• Be careful not to pinch your ngers in the gap.
Opening the Top Lid

You can place music books or sheet music on the top edge of the opened lid.
Tips for placing music
• Insert the sheet music into the groove on the top edge of the lid.
• Crease sheet music so that it will stay open.
If this does not work, use paper clips to secure it.
• If the sheet music is thin, attach it to a clipboard before placing it on the music Rest.

Turning the Power On/O
NOTE
• Once the connections have been completed (p. 11), turn on power to your various devices in the order specied. By turning on devices in the wrong
order, you risk causing malfunction and/or damage to speakers and other devices.
• Before switching the power on/o, always be sure to turn the volume down. Even with the volume turned down, you might hear some sound
when switching the power on/o. However, this is normal and does not indicate a malfunction.

After a brief interval, you’ll be able to produce sounds by playing the keyboard.
* This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is required before the unit will operate normally.
3. Use the [Volume] slider to adjust the volume.
Adjust the volume while playing something on the keyboard, so you can hear how it sounds.
The volume increases when you slide it to the right, and decreases when you slide it to the left.
MEMO
The LX-15 is designed so that nuances in the dynamics of your playing will be clearly heard even at low volume, and that the sound will remain
clear even at high volume.
Turning the power o
1. Move the [Volume] slider all the way to the left to minimize the volume.
2. Press the [Power] switch.
The power is turned o.
* If you need to turn o the power completely, rst turn o the POWER switch, then unplug the power cord from the power outlet. Refer to “Power

If you don’t want the power to turn o automatically, change the “Auto O” setting to “O”!
With the factory settings, the LX-15’s power will automatically be switched o 30 minutes after you stop playing or operating the unit.
If the unit’s power has been turned o automatically, you can use the [Power] switch to turn the unit back on again.
If you don’t want the power to turn o automatically, change the “Auto O” setting to “O” as described on “Making the Power Automatically
Turn O After a Time (Auto O)” (p. 40).
NOTE
• When turning the power on again, you must allow at least ve seconds after power-o before you once again turn the power on. If you fail
to allow enough time, the Auto O function might not be reset, preventing the power from turning on correctly.
• The settings will be initialized after the power has been turned o. If you want to still be retained the next time you turn on the power, you
should refer to “Having Your Settings Be Retained after the Power Is Turned O (Memory Backup)” (p. 40) and save your settings.

button will switch the speed of the rotary eect.
For details on the tones, refer to “Tone List” (p. 52).
