Message Meaning

When using the P-250 connected to your personal computer ...
The driver or MIDI application on your computer is not functioning correctly,
perhaps because the computer is turned off, the cable is not connected cor-
rectly, or the HOST SELECT switch is not set correctly. In this case, turn off the
power to the P-250 and your computer, and check the cable connections and
HOST SELECT switch setting. Then turn on the power first to your computer,
then to the P-250, then check that the driver and MIDI application on your
computer are functioning correctly.
When using the P-250 by itself ...
This message may appear if a cable is left connected to the [TO HOST] or
[USB] connector on the P-250. In this case, turn off the power of the P-250,
disconnect the cable, and then turn on the power again. If the cable is left con-
nected, the P-250 may not function correctly.
You turned off the power to the P-250 while it was writing a file to stor-

age memory as much as possible.

While a song was being read, the P-250 detected defects in memory.
Reset the P-250 to its normal (factory default) settings with "Memory-
FileIncluded" (page 79) after you back up all song data.
This message indicates that there may be a problem with the memory. If
the message appears repeatedly when you continue using the P-250,
back up the song data and performance file, then restore the default set-
ting by using "FactorySet" with "MemoryFileIncluded" selected
(page 79).
There is not enough memory space left and you cannot save any more
songs and files. Save or delete some songs and performance files in the
storage memory, then save new data to memory.
