9. SETTING MENU LOCKOUTS
For security and ease of operation, any or all program menu items may be disabled. Each
function to be disabled is set to "1" in the menu items, " Loc 1"," Loc 2" or "Loc 3". These lockout
menu items may in turn be "locked-out" by installing an internal hardware shorting jumper. With
the jumper installed, the operator has access only to enabled menu items.

not want the value changed by the operator.
