The hearing instrument consists of three basic parts: The hearing
instrument housing, the sound tube, and the dome.
To attach the dome, push the dome completely over the grooves on
the tube to mount it securely. It is recommended practice to check
that the dome is securely mounted on the end of the tubing before
each and every insertion into the ear canal.
The sound tube for the left ear is marked with small blue printing;
the one for the right ear has red printing.
Inserting your
hearing aid
1. Place the hearing instrument over the top of your ear.
2. Hold the tube close to the dome with the thumb and forefinger.
Insert the dome with gentle pressure into your ear canal until the
tube sits flush against the side of the face. The dome should fit
in the ear canal snugly, but not be uncomfortable.
3. Position the retention lock into the outer bowl of the ear above
the ear lobe using your index finger.
