Yamaha Clavinova PF P-100 Owner's Manual - Error Messages
ERROR MESSAGES
Whenever a problem occurs, the P-100 will display an error message to alert you to the nature of the trouble.
The meanings of the error messages are described below, together with the action you should take in response to each.
(The error messages themselves will be cleared from the display automatically as soon as you operate one of the
controls on the P-100’s upper panel.)
Backup battery low
The charge of the internal backup battery is running low. All of
your P-100’s setup data will be lost if the battery charge runs down
completely. Save any settings you may want to keep using the bulk
dump procedure, if possible, then contact your Yamaha dealer or a
Yamaha service center to have the battery replaced.
50
MIDI buffer full
The P-100 has received a greater volume of MIDI data than it can
process at one time. Take steps to reduce the amount of data the
P-100 is receiving.
MIDI data error
The P-100 had trouble receiving MIDI data. Check your cable
connections and try the operation again.
MIDI checksum error
The P-100 had trouble receiving a MIDI bulk dump. Check your
cable connections and try the operation again.
Bulk protected
The P-100 could not receive an incoming bulk dump because the
bulk protect function has not been turned off. Turn the bulk protect
off using the procedure described on page 36, then try the bulk
dump operation again.
Device number mismatch
The P-100 could not receive an incoming bulk dump because the
current receive channel (Rch) setting does not match the device
number recorded in the bulk data. The bulk data device number is
set equal to the P-100’s transmit channel (Tch) setting at the time
the data is dumped. Set the receive channel to this value using the
procedure described on page 33, then try the bulk dump operation
again.
