18.19 Security code
Access to the pumpís 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 code must first be set.
 In the fifth screen of the Setup menu select Security code using the UP and
DOWN keys. Press ENTER to confirm.
 If no code has been set, a screen is displayed inviting the user to set a main
code. Press ENTER to proceed (or STOP to return to the fifth screen of the
Setup menu).
 If a main code has been set, a screen is displayed inviting the user to set a
new main code, to set a user code (or a new user code if one has already been
set), or to cancel all codes. Choose Set main code, Set user code or Cancel
codes using the UP and DOWN keys. Press ENTER to confirm your choice.
