(it has a single pin hole on the bottom
edge)
.

the right.
2. Repeat with the other pin hole.
3. Lift the label cover clear and remove the card insert.
To replace the label cover:

2. Slide the tabs on the right-hand edge of the label cover into their slots.
3. Bow the label cover to slip the tabs on the left-hand edge of the label cover into their slots.
