Your hearing aids run on batteries. To turn the hearing aid on, insert a fresh battery into the battery door. The hearing aid will turn on once you have closed the battery door. After a few seconds, you will hear a startup jingle. The jingle is only played while the hearing aid is starting up. At this time, you can put the hearing aids on your ears.
To turn off your hearing aid, remove it from your ear and open up the battery door. When you are not wearing the hearing aid, you will want to be sure you always open the battery door completely to preserve battery life.When you are not wearing your hearing aid, you will want to be sure you always open up the battery door completely to preserve battery life.
