use any other AC power adaptor. It may cause a
malfunction.
* Not available in Australia and some other
regions. Ask your dealer for detailed
information.

hands.
• Connect the AC power adaptor to an easily
accessible AC outlet. Should you notice an
abnormality in the AC power adaptor, disconnect it
from the AC outlet immediately.
