Once you are logged into the unit, proceed to the URL http://192.168.88.89/admin (only the "/admin" needs to be added at the end of the IP Address you have entered). Once on the admin page, clicking on the menu item "Authorisation Settings" allows the user to change the username and password.
WARNING:
Please save your changes followed by clicking on "confirm changes". Do remember your new username and password as there is no way to log in if you forget. If you have forgotten your username and password, the box will need to be shipped back to Cimetrics.
