Rotate the Comfort Dial (cap) until you reach your chosen setting.
The cap snaps into place at each penetration depth setting.
We recommend a low setting (e.g. 2) if you are using the lancing device

To obtain blood you first need to prime the lancing device.
Press the plunger all the way down.
The plunger returns about a third of the way. The lancing device is now
primed.
