B) Button lock function
The button lock function serves to prevent improper use
or accidental changes to pump settings.
When the button lock is active, pressing the button has
no effect. This prevents users from accidentally access-
ing setting mode while allowing them to use setting
display mode.
Press and hold the button for more than 10 seconds, to
activate / deactivate the button lock.
When the button is held down for 10 seconds, all the
LEDs except the red LED flash for one second to indi-
cate that the button lock function has been activated/
deactivated.
C) Setting mode
To access setting mode, press and hold the button (1)
for between 2 and 10 seconds. The button lock must
be deactivated in order to change settings. Available
settings are displayed in a pre-defined sequence that
is repeated every time the button is briefly pressed
and released. If the button is not pressed for over 10
seconds, the pump exits setting mode and returns to
performance display mode. The last settings made are
saved in memory. See the table above for the meanings
of the LED sequences.
