Auto Power Off

When you are using battery power, keyboard power turns
off automatically whenever you leave it on without
performing any operation for about 6 minutes. When this
happens, press the POWER button to turn power back on.
NOTE
• Auto Power Off is disabled (it does not function) when
you are using the AC adaptor to power the keyboard.
To disable Auto Power Off
Hold down the TONE button while turning on the keyboard
to disable Auto Power Off.
• When Auto Power Off is disabled, the keyboard does not
turn off automatically no matter how long it is left with no
operation being performed.
• Auto Power Off is automatically enabled whenever you
turn on keyboard power.

Turning Off the Keyboard

• 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-97 for more information.
IMPORTANT!
• 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
or on external media to become corrupted. Once
corrupted, you may not be able to recall the data again.
