About the PIN Code
■ PIN Code
To prevent unauthorized use of the SIM card, you can set the tablet to
require entry of a PIN code each time the tablet is powered on. The PIN
code must also be entered when setting whether to require its entry.
Incorrectly entering the PIN code three consecutive times activates
the PIN lock. If the tablet becomes PIN-locked, the Personal
Unblocking Key (PUK) can be used to unlock it.
• At time of purchase, the PIN code is "1234", and entry is
"unrequired". You can always change the PIN code to any 4- to
8-digit number, and entry is "required".
Also be sure to change the PIN code to your own code if entry is
"required".
• The "PIN code" is not reset even when the tablet is initialized.
■ Personal Unblocking Key (PUK)
If the tablet becomes PIN-locked, the PUK can be entered to unlock it.
• The PUK is the predetermined 8-digit number indicated on the
back of the plastic card your SIM card was adhered to at time of
purchase.
