Product Description
The M Acoustic Earhook is an attachment to the
Advanced Bionics Naída™ CI M90 and Sky CI™ M90
sound processors. The M Acoustic Earhook allows for
the addition of acoustic amplification to the electrical
stimulation traditionally produced by a cochlear implant.
From the sound processor connector, a cable extends to
the speaker unit that transfers sound inputs through the
sound outlet into the ear canal. There are 5 sizes of the M
Acoustic Earhook for right and left ears to accommodate
dierent ear sizes and shapes. Domes attach to
the speaker unit of the acoustic earhook to provide
acomfortable fit in the ear canal.

earwax damage. Check the earwax protection regularly
and exchange it if it looks dirty or if volume or sound
quality is reduced. The earwax protection should be
replaced every four to eight weeks. The earwax protection
should be discarded after use.
Remove the dome from the speaker unit and clean the
speaker unit with a lint-free cloth.
Gently rotate the CeruShield Disk in the direction indicated
by the arrows until a free opening appears under the trash
icon.
