Note the following important precautions to avoid damage to
the power cord.
During Use
Never pull on the cord with excessive force.
Never repeatedly pull on the cord.
Never twist the cord at the base of the plug or
connector.
The power cord should not be stretched tight
while it is in use.
During Movement
Before moving the keyboard, be sure to
unplug the AC adaptor from the power outlet.
During Storage
Loop and bundle the power cord, but never
wind it around the AC adaptor.
Make sure that the keyboard is turned off before connecting
or disconnecting the AC adaptor.
Using the AC adaptor for a long time can cause it to become
warm to the touch. This is normal and does not indicate
malfunction.
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.
Auto Power Off is disabled (it does not function) when you
are using the AC adaptor to power the keyboard.
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.
Tone, rhythm, and other “main keyboard settings” in effect
when you turn off the keyboard manually by pressing
POWER button or when Auto Power Off turns off power are
still in effect the next time you turn power back on.
