User Lockout
User Lockout is achieved via the position of the LOCK jumper on the board header. Locate the header on the board
(shown below) and place the jumper in the desired position. In the Locked position all menus in this document are
locked out, and the unit will only allow brewing or grinding functions. There are two versions of the header, 10 pin
and 2 pin. Both configurations are shown below.
