Using the provided 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 M Acoustic
Earhook.
Line up the pin with the hole in the M Acoustic Earhook
and gently push it through the hole. The pin will move from
one side of the sound processor, through the M Acoustic
Earhook to the other side of the sound processor, holding
the M Acoustic Earhook in place. The pin should not come
out the other side.
