Samsung Galaxy Note 8.0 用户手册

Security 

The Security settings allow you to determine the security
level for your tablet.  

To require a numeric PIN or password to decrypt your tablet 
each time you power it on or encrypt the data on your SD 
card each time it is connected: 

1.   From the Settings screen, touch Security. 

2.   You must first set up a screen lock type, if you have not 

already done so. For more information, refer to “Lock 
Screen” on page 139. 

3.   Touch Encrypt device. For more information, read the 

displayed help screen. 

4.   Touch Encrypt external SD card to enable the 

encryption on SD card data that requires a password 
be entered each time the microSD card is connected. 

Tip: Make sure your battery is charged more than 80 percent. 

Encryption may take an hour or more. 

Use this option to set up your password when one is first
required or change your current password.  

1.   From the Settings screen, touch Security ➔ Set up/ 

change password. 

2.   Enter a new password and touch Confirm. 

3.   Enter the new password again and touch Confirm. 

To prevent another person from using your SIM card to make 
unauthorized calls or from accessing information stored on 
your SIM card, you can protect the information by using a 
PIN code. 

When enabled, your tablet asks for a PIN number each time 
you use the tablet. Using this option you can also change 
your SIM PIN number. 

1.   From the Settings screen, touch Security ➔ Set up 

SIM card lock. 

2.   Touch Lock SIM card, enter your SIM PIN code, then 

touch OK.
