Security Settings
The Security Settings section allows the operator to change the system
password. The password has a minimum length of four digits, any other
characters are not allowed. Once a valid password has been entered, it needs
to be entered a second time to protect against typos and unwanted changes.
System Name allows the operator to change the reported name of the CS-700
unit, instead of using the MAC address.
