Restoring the Original Factory Settings

You can restore the entire user memory and all system settings to
the original factory conditions.
1 Turn off the power.
2 Hold down SAVE and SYSTEM, and turn the power back on.
"All Initialize!!" appears in the display and the unit is reset to
the original factory settings.
Note
All user memory data is rewritten by the original factory data.
Before restoring the original factory settings, be sure to save all
necessary data (in a MIDI data filer, etc.).

Replacing the Memory Back-up Battery

If "Battery Low!" appears in the display when you turn on the
power, the internal memory back-up battery is nearly exhausted.
In order to preserve the user memory data, promptly request
battery replacement service from the store of purchase or a nearby
Sony dealer.
Note
User memory data may be reverted to the original factory data
when requesting battery replacement. Be sure to save important
data using an external MIDI data filer, or by writing down the
settings on a piece of paper (etc.).
