Option” menu only.
Telephone Book: Only entries in the local telephone book of the
mobile unit are deleted.
Note: When resetting the mobile unit and the telephone options
any saved emergency call number is also deleted.
Security: This menu entry allows you to prevent unauthorised use of your
telephone keypad. To do so, you require a PIN (Personal Identification

device PIN (default: “0000”) and then the new PIN twice. You require
