Have a battery inserted in the battery door
Close the battery door
Insert the hearing aid in your ear as shown in the instructions and video below. Don't forget that red is for the right ear and blue is for the left ear.
Note: Red is for the right ear. Blue is for the left ear.
Place the back of the hearing aid (Where the battery door is located) on top of your ear so that the tube hangs closer to the front of your face. Then grab the earmold and insert it into your ear.
