Troubleshooting

Problem
Power suddenly and unexpectedly turns off.
The instrument does not turn on.
A click or pop is heard when the power is
turned on or off.
Noise is heard from the speakers or
headphones.
The overall volume is low, or no sound is
heard.
Pedals do not function.
The damper pedal does not function as
expected.
Possible Cause and Solution
This is normal and the Auto Power Off function may have been activated
(page 11). If desired, disable the Auto Power Off function.
Securely insert the adaptor plug into the socket on this instrument, and
the adaptor plug into a proper AC outlet (page 10).
This is normal when electrical current is being applied to the instrument.
The noise may be due to interference caused by the use of a mobile
phone in close proximity to this instrument. Turn off the mobile phone, or
move it further away from this instrument.
The Master Volume is set too low. Set it to an appropriate level using the
[MASTER VOLUME] knob (page 12).
Make sure a pair of headphones is not connected to the headphones
jack (page 11).
Make sure that Local Control is On.
The pedal cord may not be securely connected to the [TO PEDAL] jack.
Be sure to insert the pedal cord all the way until the metal part of the
cord plug disappears from view (page 30).
The damper pedal was pressed when the power was turned on. This is
not a malfunction; release the pedal and press it again to reset the
function.
