Taking Off Your Hearing Instrument –
Earhook

To take your hearing instrument off, hold the Earmold

with your thumb and first finger. Gently pull it out of

your ear canal.

A slight twist may be needed to remove it. Do not

pull on the tube, as it may come out of the Earmold.

Once the Earmold is out of your ear, remove

the hearing instrument from behind your ear.

Note!

Even though they look the same, hearing

instruments are programmed to fit a specific

ear (right or left). Make sure the correct

hearing instrument is used with the correct

Earmold. Refer to the right and left instrument

markers on pages 18 and 20.
