Phonak Audéo B90-10 User Manual page 19

Your hearing aids are resistant to water, sweat and dust
under the following conditions:
• The battery door is fully closed. Ensure that no foreign
object such as hair is caught in the battery door when it
is closed.
• After exposure to water, sweat or dust, the hearing aid
is cleaned and dried.
• The hearing aid is used and maintained as described in
this user guide.
Hearing aids with the design-integrated Roger
receiver are also water resistant.
Hearing aids with an audio shoe and Roger X are
not water resistant.
Use of your hearing aid around water can restrict
air flow to the batteries causing it to stop working.
Should your hearing aid stop working after coming
into contact with water, refer to the
troubleshooting steps in chapter 16.
