How do I replace the dome? 1. With one hand, hold the receiver (lead) with your fingers and thumb. 2. With the other hand, pinch the dome with your thumb and forefinger. 3. Gently pull the receiver and dome apart until the dome comes off. 4. Aim the receiver directly at the middle of the inside of the new dome. 5. Press the new dome firmly into the receiver to ensure it is held securely in place. 6. If your domes are worn, or not securely fastened to the receiver, you risk losing them in the ear canal. As soon as you notice that the dome is missing, listen to it. Your ears may feel "full", just as your ears feel crowded. If you are not sure if your missing dome is stuck in your ear, visit your audiologist or doctor to have it examined through an otoscope. If they find it, they can remove the dome with specialist tools. Do not try to remove the dome from your own ear. You risk pushing the dome further into your ear and potentially injuring your ear drum or risking infection."
