Power Supply
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.
NOTE
• When this function is turned off, the keyboard does not
turn off automatically no matter how long it is left with
no operation being performed.
• Auto Power Off is enabled again when you manually
turn off power and then turn it back on again.
Memory Contents
Registration memory contents, recorder memory contents,
and song bank data you transfer from a computer to keyboard
memory are all retained when the keyboard is turned off,
either by pressing the power button or by Auto Power Off.
Electrical Power
The memory contents described above are retained as long
as the keyboard is being supplied with electrical power.
Unplugging the AC adaptor when batteries are not loaded
or when loaded batteries are dead cuts off the keyboard’s
electrical power supply. This clears all data stored in memory.
Power Requirements
Note the following precautions whenever you want to ensure
that current memory contents are not lost.
• Make sure the keyboard is being supplied power through
the AC adaptor before replacing its batteries.
• Before unplugging the AC adaptor, make sure that fresh
batteries are loaded in the keyboard.
Make sure that keyboard power is turned off before replacing
batteries or unplugging the AC adaptor.
