It's very easy to care for your hearing aids. Proper care for your hearing aids can help them last longer and lower the necessities for hearing aid repairs.
Basics of Hearing Aid Care
Movable Parts of Your Hearing Aids:
The battery doors of your hearing aids are used everyday. When you're not using your hearing aids, you should open the battery doors. Because of the oils on your skin dirt and grime can build up around the edges of the battery doors. Use the brush provided by your hearing aid specialist to clean around the edges of the battery doors.
The volume controls of your hearing instruments are used even more than your battery doors. The same problem exists with the oils on skin causing a build up of dirt and grime. This dirt and grime not only gets on top of the volume control, it also gets underneath the volume wheel eventually causing the volume control to fail. This can be stopped once again by using the brush your hearing aid specialist provided for you. Be sure to clean underneath the volume wheel as much as possible with the brush. The volume wheel should turn as you clean it so brush both clockwise and counter-clockwise.
Some hearing instruments have telephone switches and very old hearing instruments may have noise reduction switches (which were pretty useless thus only old hearing aid have them). The same situation applies here about oil from the skin and grime getting on the switch. Again use your brush to clean the hearing aids with the switch in both positions.
If one of your hearing instruments is making a buzzing sound and you cannot hear any amplification, check the telephone switch and make sure it's not toggled to telephone.
