Cause
The power cable plugs are not in-
serted either in the Clavinova or a
proper AC outlet.
Electrical current is flowing into the
instrument.
The brightness may be changed by
the surrounding temperature.
The [DISPLAY HOLD] lamp is lit.
The independent volume level of the
keyboard performance sound is too
low.
The [ACMP/SONG VOLUME] is
low.
The [MASTER VOLUME] is low.
Headphones are connected.
Local Control is set to off.
The pedal cord plug is not connected.
MIDI Sync is set to "EXT.".
Notes have been played beyond the
total simultaneous polyphonic capac-
ity (maximum number of notes).
Auto Accompaniment is not turned
on.
Solution
Securely insert one of the cable
plugs into the instrument itself, and
the other plug into a proper AC
outlet.
This is normal, and is no cause for
concern.
Adjust the contrast of the display by
using the [CONTRAST] control. (See
page 15 in the Owner's Manual.)
Press the [DISPLAY HOLD] but-
ton so that the lamp goes out. (See
page 15 in the Owner's Manual.)
Raise the volume of the keyboard per-
formance in the Mixer display. (See
page 94 in the Owner's Manual.)
Raise the [ACMP/SONG VOL-
UME] level.
Raise the [MASTER VOLUME].
Unplug the headphones.
Set Local Control to on. (See page
144 in the Owner's Manual.)
Securely insert the pedal cord plug
into the proper jack. (See page 40
in this manual for the CVP-600 and
page 48 for the CVP-98/96.)
Set MIDI Sync to "INT.". (See
page 144 in the Owner's Manual.)
The tone generation system is
configured such that later notes
have priority, occasionally resulting
in previous notes being cut off. See
the "Specifications" section on page
37 in this Manual for information
on the simultaneous polyphonic
capacity.
Press the [ACMP ON] button to
turn on Auto Accompaniment.
