Troubleshooting

Problem

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

The instrument has not been plugged in properly. Insert the plug of the

power cable into the [AC IN] jack on this instrument, then plug the other

end of the cable into the proper AC outlet on the wall (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 (page 26) is On.

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 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.
