Getting started
Security codes used on the terminal
Some functions provided for convenient use of the terminal require
the security code to use them. Besides a password for screen lock
of the terminal, a network security code necessary for the network
services, etc. are available. Make use of the terminal using an
appropriate security code according to the purpose.
• Entered PIN/password for screen lock, network security code, PIN code
and PUK code are shown as " ● ".
■ Notes on the security codes
• Avoid using a number that is easy to guess, such as "birth date", "part of
your phone number", "street address number or room number", "1111", and
"1234". Make sure to make a note of the security code you set lest you
should forget it.
• Be very careful not to let others know your security code. If your security
code is known by anyone else, DOCOMO shall have no liability for any loss
due to any unauthorized use of it.
• If you forget security codes, you should bring your official identification
(such as driver's license), the terminal, and docomo nanoUIM card with you
to the nearest docomo Shop. For details, contact the "General Inquiries" on
the last page of this manual.
• The PUK code is written on the subscription form (copy for customer)

Unblocking Key" (PUK) to unlock and then set PIN code again.

the PIN code again → "OK".
