Before fitting a hearing aid, a professional examination and hearing test must be conducted, and the hearing aid should be adjusted, tested, and worn under the guidance of a certified hearing aid specialist. Included in the package:
1 x E-8 hearing aid
8 x Earplugs (various sizes)
1 x EU Plug Charger (110-240V.)
1 x User manual
 
Note:
Adjust the volume to the minimum before wearing.
Choose an earplug that is slightly larger in size to avoid the sound of whistling.
Increase the volume gradually to avoid a sudden increase in sound.
If you hear a howling, check that the ear (silica gel) is appropriate and whether the size of the plug is tight; ensure the correct type of earplugs and plugs are used, and make sure there is no air leakage.
Keep the ear plug clean
Remove the battery if you don’t use it for a long time.
