Using password protection

By setting a password for your handheld, you ensure greater
security against others using the handheld.
You can specify the length of time that the handheld is idle before
the password security screen appears. Once the handheld is left idle
for that amount of time, you will need to type your password to use
the handheld.
You can also manually activate the password security screen by
selecting the Lock function from the Home screen. You should lock
your handheld if you leave it unattended.
If you do not want the password security screen to appear, you
must disable your password in the Security screen.
