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 brightness may be affected by
the surrounding temperature.
Either the overall keyboard volume
or the independent volume level of
the keyboard part is set too low.
The [ACMP/SONG VOLUME] is
set too low.
The volume level of one or more
accompaniment parts or song tracks
is set too low.
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 MIDI Sync function is set to EXT.
The Clavinova's total simultaneous
polyphonic capacity (maximum
number of notes) has been exceeded.
Solution
Securely insert the female plug into
the socket on the Clavinova, and the
male plug into a proper AC outlet.
This is normal, and is no cause for
concern.
Turn off the mobile phone, or use it
further away from the Clavinova.
Adjust the contrast of the display
using the [CONTRAST] control.
(See page 11.)
Increase the overall keyboard level in
the main display (page 23), or use the
VOLUME function in the appropriate
KEYBOARD display (pages 32, 34,
or 37) to raise the volume of the key-
board part in question.
Raise the [ACMP/SONG VOL-
UME] level.
Raise the part or track level(s) in the
appropriate MIXER display (page
65 or 100).
Raise the [MASTER VOLUME] level.
Unplug the headphones.
Turn the Local Control function on.
(See page 147.)
Securely insert the pedal cord plug
into the proper jack. (See page 42
in the Reference booklet.)
Set the MIDI Sync function to INT.
(See page 148.)
Since the configuration of the tone
generation system is such that later
notes have priority, previous notes
may occasionally be cut off. (See
"Specifications" in the Reference
Booklet for details about the simul-
taneous polyphonic capacity.)
