Using the provided pin removal tool, place one of the pins in the small
hole on the side of the tool. This will help to steady the pin as you line it
up with the pin hole on the earhook.
Line up the pin with the hole in the earhook and gently push it through
the hole. The pin will move from one side of the sound processor,
through the earhook to the other side of the sound processor, holding
the earhook in place. The pin should not come out the other side.
