Precautions for the secure start-up feature
If you forget your decryption password, you cannot restore encrypted

data and personal information.
Be sure to keep your screen lock passwords separately.

If you enter the screen lock passwords incorrectly more than the

specified times, the device automatically resets itself and the encrypted
data and your personal information are deleted automatically and they
cannot be restored.
Be cautious not to enter incorrect screen lock passwords more than the

specified times.
When you turn on the device right after the device reboots, encryption

also starts. If you stop the encryption arbitrarily, the data may be
damaged. Be sure to wait until the reboot is completed.
