it to overheat, or create a fire hazard.

CAUTION
• Be sure to unplug the power adaptor from the AC wall
socket during electrical storms or if the instrument is
not to be used for an extended period of time.

CAUTION
• The digital piano remains charged and draws a small
amount of power even when turned off. Be sure, therefore,
to unplug the power adaptor from the AC wall socket if it
is not to be used for an extended period of time.
NOTE
• Carry out the above procedure in reverse when disconnecting the power adaptor.
If you are going to use your instrument in a live
music situation such as on-stage, please read

Auto Power-Off

The Auto Power-Off function automatically turns off
your digital piano after a set period of inactivity in order
to save power. By default, it will turn off the instrument
after 30 minutes if it is not operated in any way.
Disabling the Auto Power-Off function
To disable the Auto Power-Off function, either set the
corresponding Function parameter to "Off" or turn on
the instrument while holding down the left-most key
on the keyboard. When disabled in this way, the
instrument will not turn off automatically.

ous screen.
NOTE
• Before the Auto Power-Off function turns off the instrument, unsaved data
will be automatically backed up. See page 46 for details of the data backed
up at this time.
NOTICE
• In certain modes of operation, the Auto Power-Off func-
tion will not turn off the digital piano when the set time
has elapsed. We recommend, therefore, that you
always turn off the instrument manually when you are
finished using it.
• If your digital piano is connected to other equipment
such as amplifiers, speakers, or a computer but you do
not intend to use it for some time, we recommend that
you turn off all devices as described in their owner's
manuals. Doing so eliminates the risk of damage to the
other equipment. If you do not want the instrument to
turn off automatically when connected to other equip-
ment, disable the Auto Power-Off function.
If you are going to use your instrument in a live music
situation such as on-stage, we recommend that you
disable the Auto Power-Off function. (See page 37, 39.)
