6. Maintenance and Care
Proper maintenance ensures the longevity and optimal performance of your hearing aids.

- Storage: When not in use, store the hearing aids in their charging case to protect them from dust and damage.
- Moisture Protection: The hearing aids are IP22 sweatproof, meaning they are protected against vertically falling drops of water when tilted up to 15 degrees. Avoid prolonged exposure to excessive moisture or submersion in water.
- Earplug Replacement: Replace earplugs periodically or if they become damaged or uncomfortable.
7. Troubleshooting and Whistling Prevention
If you experience whistling sounds or other issues, follow these steps:
Image: A visual guide detailing four steps to prevent whistling sounds: 1. Turn to minimum volume after use, 2. Choose the right earplugs, 3. Wear and adjust to the right angle, 4. Power on and slowly increase volume.
- Reduce Volume: After every use, double-click the control button until you hear one beep, indicating the minimum volume level. This helps prevent whistling when inserting the device.
- Check Earplug Fit: Ensure you are using the correct size earplug for a snug fit. A loose earplug can cause sound leakage and whistling.
- Proper Insertion: Wear and adjust the hearing aid to the right angle in your ear. It should sit comfortably and securely without feeling loose.
- Gradual Volume Increase: After inserting the hearing aid, power it on and slowly increase the volume to your desired level. Avoid immediately setting it to a high volume.
