Troubleshooting
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 9).
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.
Electrical current is being applied to the instrument. This is normal.
• The Volume is set too low: set it to an appropriate level using the [MASTER VOLUME] control
(page 10).
• Make sure a pair of headphones is not connected to the headphones jack (page 11).
• Make sure that Local Control (page 34) is on.
The Piano Voices attempt to precisely simulate actual piano sounds. However, as a result of sam-
pling algorithms, overtones in some ranges may sound exaggerated, producing a somewhat dif-
ferent 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 (page 10).
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.
• The pedal cord may not be securely connected to the [PEDAL] jack. Be sure to insert the pedal
cord all the way until the metal part of the cord plug disappears from view (page 38).
• 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 26).
