Cleaning my Wax Guards

If your EV3s are not emitting sound, then it may be time to clean or replace your wax guards. The wax guard is the small white circular piece that goes on the end of the receiver: the side of the hearing aid that goes into your ear canal (this is not the soft silicone earbud, it is the hard white plastic piece
underneath it). If the wax guard becomes clogged with ear wax, the sound from the receiver inside of the hearing aid will not be able to project into your ear.

We recommend that you start this process by turning off your EV3, removing the wax guard, and cleaning both the wax guard and device with an alcohol swab. Use the small cleaning brush to break up any hardened earwax on the wax guard or device. Do this over a table/desk to make sure that you do not
lose the small white wax guard. 

Once you have cleaned the wax guard, reinsert it into the hearing aid and turn the hearing aid on, making sure it is at the lowest volume setting. Slowly adjust the volume dial clockwise, until you reach your desired volume setting. Now your wax guards are clean and your hearing aids are ready to be used.
