1. Applicable to: People over 18 years old with moderate/mild air conduction hearing loss. Affordable hearing aids provide scientific self-fitting functions and are loved and welcomed by users.
2. Although self-fitting hearing aids are IP64 waterproof, you still need to be careful not to immerse the hearing aids in any liquid. You should remove the hearing aids before swimming, washing your hair or taking a bath; after swimming or taking a bath, wait until the ear canal is dry before wearing the hearing aids.
3. During use, keep the outer surface of the hearing aid clean and use a brush to clean the earwax in the earplug. The product should be moisture-proof, shock-proof, high temperature-proof, light-proof, and drop-proof. It can be placed in a box with a desiccant.
4. The body of the digital hearing aid is equipped with a raised physical volume control button to avoid accidental touches during use by middle-aged and elderly people. However, the function and volume control switches should be used correctly, and they should be turned on and off gently to avoid excessive force.
5. Earplugs provided by the fitting center or manufacturer should be selected to prevent discomfort caused by earplugs of different specifications during use.
6. Please use the noise reduction hearing aid with the matching small and portable charging box. It supports a total of 48 hours of use.
7. Turn off the hearing aid when not in use to avoid long-term discharge and affect the battery life. When not in use for a long time, the hearing aid and the charging box should be charged regularly. It is recommended to fully charge them every 1 to 3 months.
8. The battery is not removable. If you need to replace the battery, please contact after-sales service.
9. Choose earplugs provided by the fitting center or manufacturer to prevent discomfort caused by earplugs of different specifications. The earplugs delivered with the hearing aid can be reused.
After the earplugs are installed, pull the earplugs appropriately by hand to see if they are installed firmly to ensure that the earplugs are not easy to fall off.
If TWS hearing aid has a whistling phenomenon, you should check whether the earplugs are not properly inserted into the ears. If you confirm that the wearing is correct and the whistling still exists, you can try to replace another earplug that fits your ear size. If it still whistles, you can appropriately reduce the volume until it is comfortable.
10. Occlusion effect: When using headphones, ear molds or in-ear hearing aids, a closed air-filled cavity will be formed in the external auditory canal. When sound is generated in the human body, the sound cannot leave the ear canal and will continue to reach the eardrum. The hearing aid will amplify the sound and we will hear our own voice.
