sales package of the communicator. For security reasons, it is
imperative that you change the lock code. Change the code either in
the Security options menu of the phone (see ?Settings (Menu 4)? on
page 159), or via the communicator interface (see ?To change the
security settings? on page 128). Keep the new code secret and in a safe
place, separate from the communicator.
