Cause
The Clavinova has not been
plugged in properly.
Electrical current is being applied to
the instrument.
The noise may be due to interfer-
ence 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 con-
nected.
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.
The Clavinova's keyboard mecha-
nism simulates the keyboard mech-
anism 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 out-
let. (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.
