6. Troubleshooting
If you encounter any issues with your hearing aids, please refer to the following common solutions:
- Q: Why is there no sound when wearing it?
- A: Check if the volume is suitable for your hearing. Check whether the hearing aid has electricity. Check whether there is earwax in the ear canal.
- Q: Why do I feel uncomfortable and unrealistic sound when using a hearing aid for the first time?
- A: It's common to feel overwhelmed when first using a hearing aid; hearing sounds may seem unrealistic. It takes time to adjust. Follow usage recommendations, gradually increase wearing time, and be patient. Soon, you'll grow to love it.
- Q: Why is there a whistling (sharp sound)?
- A: If hearing aids don't fit right, they can make a whistle sound. This is because the sound from the receiver goes back into the microphone and gets louder and louder, causing the whistle.
- Q: How can we eliminate the whistling?
- A: Solution: Please select a dome that fits your ear canal size and ensure that it is securely fitted to your ear. Try out all the available sizes, and once you find the one that best suits your ear, you will never hear any whistling sound again.
- Q: How can I care for my hearing aid?
- A: Avoid heat and moisture for hearing aids. Clean hearing aids as instructed to prevent damage from earwax and ear drainage. No hairspray while wearing. Turn off when not in use.
