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.
