Security
From the More menu, touch Security. The Security
menu displays. The following options are available:
• Encryption:
As a security measure, you can encrypt the contents of
the phone or an installed memory card, and require a
password each time you turn on the phone or access the
memory card.
Encryption may take an hour or more to complete. Start
with a charged battery, and attach the charger until
encryption is complete. Loss of power or other
interruption may cause the loss of some or all data.
Once your information is encrypted you are prompted to
enter your decryption password each time you turn the
phone on.
