How to insert and remove your Core One

Inserting your Core One correctly ensures a secure fit, better sound quality, and less feedback.

Identifying left and right

• The left hearing aid is marked with a blue indicator; the right is marked red.

Inserting the hearing aids

1. Hold the hearing aid by its body and grasp the removal thread. Insert it gently into your ear canal with the thread pointing downward.
2. Guide it in until it feels comfortable and secure. Do not force it deeper than is comfortable.
3. Give the hearing aid a gentle tug to confirm it is seated properly and will not fall out.

Removing the hearing aids

1. Grasp the removal thread that hangs from the hearing aid.
2. Pull the hearing aid out of your ear gently.
3. Place it in the charging case when not in use.

Tips

• If the hearing aid feels uncomfortable or causes whistling, try a different ear-tip size or switch between open and closed ear tips.
• Do not use tweezers or cotton swabs to remove the hearing aid from your ear.
