<Scanning function>
Protecting the FOMA Terminal from Harmful Data
Firstly update the pattern data.
When the FOMA terminal is downloading external files or programs from sites or i-mode messages,
this function scans the data and deletes any data or cancels program launch where the data or
program could cause a fault.
d
Pattern data is used for the check. Update the pattern data when it is upgraded because a problem has
been detected.

d
The scanning function prevents data that causes some problems from invading your FOMA terminal when
viewing a site or receiving a message. If the pattern data that fixes the error is not installed on your FOMA
terminal or if the pattern data does not exist, the scanning function cannot prevent the error from occurring.
d
The pattern data varies depending on the model of the FOMA terminal. As a matter of convenience, NTT DoCoMo
may discontinue to distribute pattern data for the model if three years have passed since it was first released.
d
Ensure that the correct date (year, month and day) is set on the FOMA terminal.
d
When you set the auto-update or update the pattern data, the FOMA terminal-specific information (model,
manufacturer number, etc.) is automatically sent to the server (the server for pattern data updates
managed by DoCoMo). The information sent to DoCoMo is used only for the scanning function.
d
The pattern data update will be suspended if a voice call is received or if the terminal moves out of range.
Setting the scanning function <Set scan>
Setting the scanning function to "ON" will check data and programs automatically when they are
