Select Dome
•
Place the hearing aid (powered on) in your ear (reference page
30) with the dome attached to the thin tube. Open and close
your jaw with a chewing motion several times to ensure the
dome doesn’t move out of your ear. Use the guide below to
help select another dome if necessary.
•
Keep in mind:
- With a smaller, open dome, your voice is likely to sound
more natural.
- With a larger, closed dome, you may feel like you’re speaking
in a barrel.
- Always start with trying smallest to largest open domes.
Then, try smallest to largest closed domes.
