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 functions. There are two versions of the header, 10 pin and 2 pin.
Both configurations are shown below.

System Restore Function
This function will restore a Precision Brew® unit to its original factory settings. To activate system restore, power on
the unit while holding in the DOWN button on the keypad (use the keypad that controls the RIGHT side for a double
unit).
Continue holding the DOWN button and the display will scroll “rEStorE” to indicate that a system restore is about to
happen. If the DOWN button is released at this point, the restore is cancelled. If the button hold is continued, the
display will scroll “donE” to show completion of a system restore.
Upon a successful restore, the original factory settings will override all changes. The brew counters are not affected.
Factory Specific Features
The following sections describe features that are not intended to be used by the end user. These features, instead,
are intended to help Grindmaster set up and test the machine.
Factory/Field Test Menu
This menu is intended to check product functionality both at the end of the factory line and in the field. The con-
trol must be completely OFF (both sides) to enter field test. This mode is entered by pressing and holding the UP
key and the LARGE BREW key on the keypad (use the keypad that controls the RIGHT side for a double unit)
for 6 seconds. Once the menu is entered, the unit will start with an LED test that lights all LEDs and segments
on the display.
Proceeding through the field test is done by pressing the ON/OFF key (RIGHT side if a double unit). Each time
this button is pressed, the test will advance to the next step. For the output test, use the UP and DOWN keys to
select the desired output.
Refer to the table on the following page for operation. Field Test Mode exits after stepping through all modes
only- there is not a timeout.
