ume of fluid has been
dispensed, press the
STOP key twice within
half a second. This
starts the MemoDose
feature.
The pump has made a record of the fluid it has just dispensed.
You may now repeat this dose or adjust the quantity as required.

change to show 100%.

correct press START to repeat the dose.
If the initial dose is larger than required use
