1. Take the black cap off the lancing device by
pulling it straight off. It is not a twist cap. The
easiest way to do this is to place your thumb to
the side of the notch as seen in the illustration.
NOTE
A used drum cannot be reinserted into the lancing device.
2. Hold the drum between your thumb and index
finger and pull it straight out of the lancing
device. A red stripe is visible on the white part,
indicating that the drum has been used.
