• Be sure to press the POWER button to turn off power and
make sure that the LCD backlight is off before
disconnecting the AC adaptor or doing anything else.
• Never disconnect the AC adaptor while the keyboard is
turned on or try to turn off power using any other
technique besides pressing the POWER button. Doing so
can cause the contents of the keyboard's Flash memory to
become corrupted. Strange keyboard operation and
abnormal startup when power is turned on are symptoms
of corrupted Flash memory contents. See
“Troubleshooting” on page E-78 for more information.
• While the following message is on the display, never turn off
the keyboard by pressing the POWER button, disconnecting
the AC adaptor, etc.
(message)“Pls Wait” or “Bulk In”
Turning off the keyboard while the above message is on the
display can cause user data (user tones, song memory data,
etc.) currently stored in keyboard memory to become
corrupted. Once corrupted, you may not be able to recall the
data again.
In addition to the above settings, data stored in the
Registration Mode and Song Memory Mode is also retained
when keyboard power is turned off.
J About Flash memory
Your keyboard comes with built-in Flash memory, which can
continue to hold data even when electrical power is totally cut
off. This means that even after batteries go completely dead,
you can attach the AC adaptor, turn on power, and still recall
data stored in memory.
• When running under battery power, be sure to replace
batteries as soon as possible after the first signs of low
battery power (dim power indicator lamp, dim display
characters, etc.) Though the keyboard’s Flash memory is
non-volatile (which means that data is not lost when power is
interrupted), data can be lost if power suddenly fails while
data is being written to flash memory*.
* While storing or deleting user data, while recording with
the synthesizer, while transferring data from a computer,
etc.
J Backing Up Data to a Computer
You can use a MIDI connection to back up keyboard settings
and memory contents on a computer’s hard disk. See
“MIDI”on page E-75 for more information.
Initialization can be used to return keyboard parameters to
their initial factory default settings, or to delete all data
currently in keyboard memory. See page E-70 for more
information about initialization.
Returning the keyboard to its initial factory defaults
You can use the CD-ROM that comes with the keyboard and
your computer to return the keyboard’s flash memory and all
of its parameters to their initial factory default settings. See
“Bundled CD-ROM Data” on page E-76 for details.
