Access to the pump’s Setup and Calibration menus, direction control and keypad lock
can be restricted to those who correctly enter a three-digit security code: the main
code. A secondary user code can be set, which permits PIN access to calibration,
direction and keypad lock, but blocks access to Setup. See 18

code. Press

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

to confirm your choice.

to the pump is not restricted.

Set user code
, the pump displays a screen
with three blank spaces for digits and the instruction “Enter new code”. Use the
numeric keys to enter three digits. The pump displays a similar three-digit
entry screen and the instruction “Confirm code”.
