Troubleshooting Problem The Clavinova does not turn on. A click or pop is heard when the power is turned on or off. Noise is heard from the Clavinova's speakers. The overall volume is low, or no sound is heard. The damper pedal has no effect, or the sound continuously sustains even when the damper pedal is not pressed. The pitch and/or tone of the piano voices in certain ranges do not sound right. Mechanical noise is heard during performance. Cause The Clavinova has not been plugged in properly. 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 the Clavinova. The [MASTER VOLUME] is set too low. Headphones are connected. The Local Control function is turned off. The pedal cord plug is not connected. 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 exaggerated, producing a somewhat different pitch or tone. The Clavinova's keyboard mechanism simulates the keyboard mechanism of a piano. Mechanical noise is also heard on a piano. Solution Securely insert the female plug into the socket on the Clavinova, and the male plug into a proper AC outlet. (See page 19.) This is normal, and is no cause for concern. Turn off the mobile phone, or use it further away from the Clavinova. Raise the [MASTER VOLUME] level. (See page 20.) Unplug the headphones. (See page 20.) Turn the Local Control function on. (See page 85.) Securely insert the pedal cord plug into the proper jack. (See step 5 on page 107.) This is normal. This is normal. 100 CLP-970

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 19.)
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 overall volume is low, or no
sound is heard.
The [MASTER VOLUME] is set too
low.
Raise the [MASTER VOLUME]
level. (See page 20.)
Headphones are connected.
Unplug the headphones. (See page
20.)
The Local Control function is turned
off.
Turn the Local Control function on.
(See page 85.)
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 107.)
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.
