Troubleshooting
* For information on other specific problems and explanations of display messages, see the Message List (page 42).
Problem Possible Cause and Solution
The instrument does not turn on.
The instrument has not been plugged in properly. Securely insert the female plug into
the socket on the instrument, and the male plug into a proper AC outlet (page 12).
A click or pop is heard when the power is
turned on or off.
Electrical current is being applied to the instrument. This is normal.
The power is automatically turned off.
This is normal and due to the Auto Power Off function. If necessary, set the parameter
of the Auto Power Off function (page 13).
Noise is heard from the instrument’s
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.
Noise is heard from the instrument’s
speakers or headphones when using the
instrument with your smart device, such as
an iPhone/iPad.
When you use the instrument along with your smart device, we recommend that you
set that device’s “Airplane Mode” to on and then the Wi-Fi/Bluetooth setting to on on
your smart device, in order to avoid noise caused by communication.
The overall volume is low, or no sound is
heard.
The volume is set too low: set it to an appropriate level using the [MASTER VOLUME]
control (page 14).
Make sure a pair of headphones or an adapter plug is not connected to the [PHONES]
jack (page 15).
Make sure that Local Control (page 37) is on.
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. This is normal, and no cause for concern.
Sound is not heard on a particular key.
Keyboard may not function normally if the key was pressed when the power was turned
on. Turn off the power and turn it on again to reset the function. Do not touch any keys
when turning the power on (page 12).
Mechanical noise is heard during
performance.
This is normal. The keyboard mechanism of this instrument is the same as that of an
actual piano, which also has mechanical noise.
The key you pressed does not return to the
original position smoothly.
Since the keyboard mechanism of this instrument is the same as that of an actual
piano, the mechanism may change over years of use. If this occurs or causes problems
in performance, contact your Yamaha dealer.
Some keys sound louder or quieter than
other keys.
Sound input to the [AUX IN] jacks is
interrupted.
The output volume of the external device connected to this instrument is too low,
resulting in the sound being cut off via the Noise Gate after it is input to this instrument.
• Increase the output volume of the external device. The volume level reproduced via
this instrument’s speakers can be adjusted by using the [MASTER VOLUME] control.
• Set the Noise Gate to off (page 36).
The damper pedal has no effect.
The pedal cord may not be securely connected to the [PEDAL] jack. Turn off the power
to the instrument first, and then insert the pedal cord to the [PEDAL] jack all the way
until the metal part of the cord plug disappears from view (page 46).
The damper pedal was pressed when the power was turned on. This is not a
malfunction; press the pedal again to reset the function.
The USB flash drive has hung up (stopped).
Disconnect the USB flash drive and connect it to the instrument again.
The USB flash drive is not compatible with the instrument. Only use the USB flash drive
whose compatibility has been confirmed by Yamaha (page 31).
Higher or lower notes do not sound correctly
when the transpose setting is made.
The instrument can cover a range of C-2–G8 when you set the transposition. If notes
lower than C-2 are played, the actual resulting sound is one octave higher. If notes
higher than G8 are played, the resulting sound is one octave lower.
The Bluetooth-equipped device cannot be
paired with nor connected to this instrument.
The Bluetooth function of the instrument is off; make sure that it is turned on (page 41).
The Bluetooth-equipped device is not paired with this instrument. The device and this
instrument need to be paired to each other via Bluetooth (page 41).
The Bluetooth function of the Bluetooth-equipped device is not activated. Make sure
that the function is activated.
This instrument and the Bluetooth-equipped device are too far apart. Use the device in
close proximity to this instrument.
There is a device (microwave oven, wireless LAN device, etc.) that outputs signals in
the 2.4 GHz frequency band nearby. Move the instrument away from any devices that
might be emitting radio-frequency signals.
Sound input via Bluetooth is interrupted.
The output volume of the Bluetooth-equipped device connected to this instrument is
too low, resulting in the sound being cut off via the Noise Gate after it is input to this
instrument. Increase the output volume of the device. The volume level reproduced via
this instrument’s speakers can be adjusted by using the [MASTER VOLUME] control.
