Attach the dome by holding the speaker unit in one hand
and the dome in the other.
Slide the dome over the speaker unit sound outlet. The
speaker unit and the dome should fit perfectly together.
For a more custom fit, the Phonak SlimTip is an optional
earpiece that may be used in place of the provided
dome. The SlimTip must be ordered from Phonak; it is
not provided with the M Acoustic Earhook. Contact your
cochlear implant professional for more details.
