Cautions
Impact to the sound processor can cause damage to the
processor or its parts. Impact to the head in the area of the
implant can cause damage to the implant and result in its
failure. Young children who are developing motor skills are
at greater risk of impact to the head from a hard object (e.g.
a table or a chair).
