The controller can be reset at any time to the default factory settings.
Follow the steps below:
A.
Turn the controller ‘off’ by holding down the mode button
B.
Simultaneously depress and hold the ‘Set Level’ and ‘pH
Calib’ buttons
C.
Turn the controller ‘on’ by pushing the mode button
D.
The display will read ‘LD’
E.
Release the ‘Set Level’ and ‘pH Calib’ buttons
F.

Note: This last step is extremely important since this puts
the controller back in the operating mode. If step F is not
performed, the controller is in the test mode and it will not
operate correctly.
