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 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 are used and properly inserted to prevent any air leakage.
Keep the ear plug clean
Remove the battery if you don’t use it for a long time.
