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

If a small portion of the pin extends beyond the sound
processor, use the side of the tool to push the pin inwards
so it lies flush with the sound processor.
