PIN
■ 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 PIN code entry is required.
If PIN code is incorrectly entered three times consecutively, the PIN code will
be locked. You can unlock the PIN code using PUK code.
• At the time of purchase, the PIN code is "1234", and entry requirement is
"not required". You can change the PIN code to any 4- to 8-digit number and
the entry requirement to "required" if necessary.
To use the product with a PIN code "required", be sure to change the PIN
code to your own number you have chosen.
■ PUK Code
In case PIN code is locked, you can unlock it by entering 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 on which your au IC Card is
attached.
• After entering PUK code, you need to set a new PIN code.
• If PUK code is incorrectly entered ten times consecutively, contact an au
shop, Toyota store or Customer Center.
• "PIN code" is not reset by initializing the product.
◎ When the PIN code is locked, the product may restart for the security
reasons.
