Problem #1: My hearing aid is not producing any sound
Replace the battery and make sure that the batteries are new
Check to make sure there is no wax blocking any of the surfaces of the hearing aid or earmold
Open and close the battery door OR turn the hearing aid off and back on
Problem #2: My hearing aid is not loud enough
Visually examine the hearing aid to make sure there is no wax blocking any of the surfaces of the hearing aid or earmold
Change the battery
Problem #3: My hearing aids are whistling
Remove the hearing aid and re-insert it into your ear
Make sure the seal of the earmold is tight and there are no cracks in the earmold
You may have wax in your ear canals that should be removed by a physician
Problem #4: How do I clean my hearing aids?
Wear gloves when cleaning hearing aids.
When handling behind-the-ear hearing aids, clean the hearing aid surface with wet wipes that don't contain alcohol. This is because they are coated with a hydrophobic coating that is sensitive to alcohol.
For in-the-ear hearing aids, all kinds of wet wipes can be used for cleaning the hearing aids' surface.
An alternative to wet wipes is cleaning with a mild soap solution on a hard-twisted cotton cloth. Avoid using excess water that can enter the hearing aids.
After cleaning, discard the gloves and wash your hands carefully with soap and water or with a suitable alcohol disinfectant.
Let your cleaned hearing aids dry for one hour.
