18.19 Security code
Access to the pump‘s Setup menu, direction control and keypad lock can be restrict-
ed to those who correctly enter a three-digit security code: the main code. A sec-
ondary user code can be set, which permits PIN access to direction and keypad lock,
but blocks access to Setup. See 18 Setup, 14.1 Keypad functions in manual mode
and 14.2 Keypad lock.
The codes must first be set.
