Let's get to cleaning! First, you will want to turn your EV3s to the off position. With an alcohol swab, wipe down your EV3s and the charging dock, cleaning both the small circular golden adapters on the aids and
within the charging ports on the charging dock.
Once you have done this, take the small brush and use it to break up any dirt or debris on your EV3s. Brush the microphone and the receiver, as well as the micro-USB port on the charging dock. Try to repeat this routine every week to two weeks.
