Troubleshooting
Problem Possible cause and solution
The digital piano turns off unexpectedly.
This does not indicate a problem—the Auto Power-Off function turns off the
instrument after the set period of inactivity. If necessary, you can deactivate
this function to prevent it turning off the digital piano again (page 10).
The digital piano will not turn on.
The instrument may not have been plugged in correctly. Ensure that the power
adaptor is securely connected to the digital piano and a domestic-use, AC wall
socket (page 10).
A click or pop can be heard when turning the digital
piano on or off.
This type of noise can occur when a device is charged and does not indicate a
problem.
Noise can be heard coming from the digital piano.
Noise may be caused by interference when a mobile phone in the vicinity of
the instrument is used. Try turning off any mobile phone located close to the
digital piano.
Noise can be heard coming from the digital piano’s
built-in speakers and/or headphones when using it
with an iPad, iPhone, or iPod touch app.
I
n order to eliminate the risk of noise from other communication when using
the instrument with an iPad, iPhone, or iPod touch, we recommend turning on
the devices Airplane Mode.
The overall volume is low or nothing can be heard.
The digital piano’s master volume may be turned down. Try moving the [MAS-
TER VOLUME] slider to the right (page 11).
If headphones are connected to the instrument, try unplugging them (page
11).
The digital piano’s speakers are turned off. Please turn them back on (page
44).
If local control has been turned off, try turning it back on (page 45).
The sound is distorted.
The volume has been set too high.
•Turn down the volume using the [MASTER VOLUME] slider (page 11).
•Move the [EQ] sliders downward (page 17).
•Turn off the Sound Boost function (page 18).
Pedals have no effect.
The pedal cord may not be securely connected to the [SUSTAIN PEDAL] jack
or the [PEDAL UNI
T] terminal. With the digital piano turned off, insert the
cord’s plu g securely into the correct jack or terminal. When fully inserted, none
of the metal section of the plug will be visible (pages 11, 12).
The pitch or tone of a Piano Voice sounds strange
in a specific frequency range.
The instrument’s Piano Voices have been carefully designed to recreate the
sounds of a real piano as faithfully as possible. In certain frequency ranges,
therefore, harmonics may appear accentuated or the pitch may not seem quite
right; however, this does not indicate a problem.
The keyboard makes a mechanical noise when
played.
Yo ur digital piano’s keyboard has been specially designed to simulate the feel
of a real piano keyboard. Even real pianos can make a mechanical noise when
played, and this does not indicate a problem.
The USB flash drive plugged into the digital piano
freezes and/or stops working.
If a message has been shown on the display, refer to the section Display Mes-
sages (page 49) for more information. If no message has been shown, the
USB flash drive may be broken.
