● PIN...code ...
To prevent unauthorized use of the au IC card
by a third party, you can set the product to
require PIN code entry every time the power
is turned on. You also need to enter PIN code
when setting whether the PIN code entry is
required.
If the PIN code is incorrectly entered three
times consecutively, the PIN code will be
locked. Use the PUK code to unlock the PIN
code.
• PIN code is "1234" and PIN code entry
was set to not be required at the time of
purchase. You can change PIN code to any
four- to eight-digit number, and set the PIN
code entry to be required as necessary.
If you require a PIN code to be entered,
make sure to change the number to your
own unique number.
● PUK...code ...
In case the PIN code is locked, you can
unlock it by entering the PUK code.
• PUK code is an eight-digit number given
at the time of purchase, which is printed
on the back side of the plastic card where
your au IC card is attached.
• After entering the PUK code, you need to
set a new PIN code.
• If the PUK code is incorrectly entered ten
times consecutively, contact an au shop/
au Style, Toyota store or the Customer
Center.
• "PIN code" is not reset by initializing the
product.
