Troubleshooting
Problem Cause Solution
The Clavinova does not turn on.
The Clavinova has not been
plugged in properly.
Securely insert the female plug into
the socket on the Clavinova, and
the male plug into a proper AC out­
let. (See page 17.)
A click or pop is heard when the
power is turned on or off.
Electrical current is being applied to
the instrument.
This is normal, and is no cause for
concern.
Noise is heard from the Clavinova’s
speakers.
The noise may be due to interfer­
ence caused by the use of a mobile
phone in close proximity to the
Clavinova.
Turn off the mobile phone, or use it
further away from the Clavinova.
The [MASTER VOLUME] is set too
low.
Raise the [MASTER VOLUME]
level. (See page 18.)
The overall volume is low, or no
sound is heard.
Headphones are connected.
Unplug the headphones. (See page
18.)
The Local Control function is turned
off.
Turn the Local Control function on.
(See page 79.)
The damper pedal has no effect, or
the sound continuously sustains
even when the damper pedal is not
pressed.
The pedal cord plug is not con­
nected.
Securely insert the pedal cord plug
into the proper jack. (See step 5 on
page 97.)
The pitch and/or tone of the piano
voices in certain ranges do not
sound right.
The Clavinova’s piano voices
attempt to precisely simulate actual
piano sounds. However, as a result
of sampling algorithms, overtones
in some ranges may sound exag­
gerated, producing a somewhat dif­
ferent pitch or tone.
This is normal.
Mechanical noise is heard during
performance.
The Clavinova’s keyboard mecha­
nism simulates the keyboard mech­
anism of a piano. Mechanical noise
is also heard on a piano.
This is normal.
