￿If you chose Cancel codes, any codes previously set are cancelled and access to the pump is not restricted.

￿If you chose Set main code or Set user code, the pump displays a screen with three blank spaces for digits and the instruction “Enter new code”. Use the UP and DOWN keys to enter three digits. Press ENTER to confirm each one.

The pump displays a similar three-digit entry screen and the instruction “Confirm code”.￿ Repeat the digit-entry sequence.

￿If the second three-digit code entered differs from the first, or if the digits cho- sen as a user code are the same as those already set as a main code, the pump briefly displays an error message and redisplays the set code options screen.

￿If the codes tally and, for a user code, if there is no clash with a previously set main code, the pump briefly displays a confirmation message and redisplays the sixth Setup screen. Access to the Setup and Configuration menus, Dose, direction control and keypad lock is now protected by the new security code.

￿If STOP is pressed during code entry, the pump returns the user to the fifth Setup screen. If STOP is pressed during code confirmation, the pump returns the user to the first digit-entry screen.

Note: A user code cannot be set unless a main code has previously been set. If you wish to cancel only a user code, you must use Cancel codes to cancel both user and main codes, then use Set main code to set a new main code.

Note: If a code has been set but forgotten, it is still possible to access the Setup screens to cancel the code or reset it to another three-digit number. Contact your supplier or Watson-Marlow Technical support for the bypass sequence.
