Cause
The power cable is not plugged in
(check at the Clavinova and at the
electrical outlet).
This is caused by the electrical
power within the instrument.

near the Clavinova (or the ring tone
is sounding).

ered.
Headphones are connected (only if
the Speaker setting is "Normal

"Expression" is assigned to one of
the right, center, and left pedals.

performance is set too low.
Speaker setting is On.

adjusted correctly.
The plug of the pedal cable is not
inserted into the [PEDAL] jack.
Solution

into the Clavinova and into the elec-
trical outlet of the correct voltage.
