❖Encryption is irreversible. The only way to revert to an
unencrypted device is to perform a factory data reset,
which will erase all your data.
❖You must not interrupt the encryption process or you
will lose some or all of your data. (See “Backup &
reset settings” on page 78 and “If Something Goes
Wrong” on page 106).
1Before starting the encryption process on your tablet,
you must:
❖Set a lock screen PIN or password (see “Securing
your tablet” on page 50).
❖Charge your tablet’s battery.
❖Plug your tablet to the USB/AC adaptor.
❖Schedule an hour or more for the encryption
process.

exit the encryption process.
3Touch the Encrypt tablet button.
4Enter your lock screen PIN or password and touch
Continue.
5Touch the Encrypt tablet button again, to confirm you
want to continue.
The encryption process begins and displays the progress.
Encryption can take an hour or more, during which time your
tablet may restart several times.
When encryption is complete, you are prompted to enter
your PIN or password. Subsequently, you must enter your
PIN or password each time you power on your tablet, to
decrypt it.
