Problem Cause Solution<br />

The power of the Clavinova does<br />

not turn on.<br />

There is a clicking noise when you<br />

press [POWER] to turn the power<br />

on or off.<br />

Noise is heard from the Clavinova.<br />

The overall volume is too low. Or,<br />

there is no sound at all.<br />

The keyboard volume is lower than<br />

the song playback volume.<br />

Sound is still heard from the speakers<br />

even though headphones are<br />

plugged in.<br />

turned ON.<br />

notes are sustained even though<br />

the damper pedal is not pressed.<br />

The power cable is not plugged in<br />

(check at the Clavinova and at the<br />

electrical outlet).<br />

This is caused by the electrical<br />

power within the instrument.<br />

A portable telephone is being used<br />

near the Clavinova (or the ring tone<br />

is sounding).<br />

The [MASTER VOLUME] is lowered.<br />

Headphones are connected (only if<br />

the Speaker setting is “Normal<br />

HeadphoneSW”). (page 95)<br />

Insert the power cable plug firmly<br />

into the Clavinova and into the electrical<br />

outlet of the correct voltage.<br />

(page 17)<br />

This is not a malfunction.<br />

Turn off the power of the portable<br />

telephone located near the Clavinova.<br />

the jacks. (page 116)<br />
