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 accessing
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 indicate 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.
