Notes

1. Avoid any liquid entering the hearing aid and damaging its parts.

2. Avoid exposing the hearing aid to high temperatures.

3. Avoid dropping the hearing aid on the ground, as this will damage the fragile parts inside.

4. Avoid inserting foreign objects into the hearing aid, which may cause serious damage.

5. Avoid spraying hairspray, perfume, etc. directly on the hearing aid. These liquids can easily stick to the volume controller and microphone.

6. Patience and continuous practice are the only ways to adapt to hearing aids. Hearing aids cannot restore your hearing to normal, nor can they help you avoid or improve hearing impairment caused by physiological factors.

7. For most people, only using hearing aids occasionally will not get sufficient help from hearing aids.
