Troubleshooting

Possible Cause and Solution
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 10).
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 Volume is set too low: set it to an appropriate level using the [MASTER VOL-
UME] control (page 12).
• Make sure a pair of headphones is not connected to the headphones jack (page 14).
• Make sure that Local Control (page 38) is on.
When the TRS is on, sound can be heard slightly even if the headphones are con-
nected. Turn the TRS off to mute all sound other than the headphones (page 23).
When the TRS (page 23) is on, sound can be heard to some degree even when the
volume is set to the minimum. This is normal, and is not a malfunction.
The Piano Voices attempt to precisely simulate actual piano sounds. However, as a
result of sampling algorithms, overtones in some ranges may sound exaggerated, pro-
ducing a somewhat different pitch or tone. This is normal, and no cause for concern.
Keyboard may not function normally if the key was pressed when the power was
turned on. Turn off the power and turn it again to reset the function. Do not touch any
keys when turning the power on.
The output volume of the external device connected to this instrument is too low.
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.
(N3)
• The pedal cord may not be properly connected. Make sure to securely insert
the pedal cord into the pedal jack (page 42).
(N2)
• The damper pedal was pressed when the power was turned on. This is not a
malfunction; press the pedal again to reset the function.
• Disconnect the device and connect it to the instrument again.
• The USB flash memory is not compatible with the instrument. Only use the USB
flash memory device whose compatibility has been confirmed by Yamaha (page 30).
