 In this video, you will learn how to apply the Adhear system. First, make sure the hairless area of skin behind the ear is big enough for the adhesive adapter. If it isn't big enough, adjust the hairline with a razor. The skin must be clean and dry before you apply the adhesive adapter. Clean the skin thoroughly and let it dry completely before you start. You can use the positioning tool to help you correctly position the adhesive adapter. Place the adapter in the tool and remove the protective film. Do not touch the adhesive surface. If you do accidentally touch it or if you put the adapter in the wrong place on the skin, simply try again with a new one. Make sure that the skin behind the ear is free from hair and move any hair away from the area. Hold the positioning tool so that it is touching the ear with the adapter placed over hard bone. Press the tool down firmly. Gently remove the tool by moving it straight upwards. Take care that you do not pull against the adhesive adapter when removing the tool. Press down firmly on the entire surface of the adhesive adapter for at least 30 to 60 seconds. Before you connect the audio processor to the adhesive adapter behind the ear, it's good to practice on a table or the back of your hand. Find the correct position and tilt the audio processor onto the snap connector while pressing down on the adhesive adapter. To disconnect the audio processor, press down on the long side of the audio processor. Then tilt it off the adapter. Remove the audio processor gently and do not pull on the adapter. You can also practice with your eyes closed to get a better feel for the process. When you connect the audio processor to the adhesive adapter behind your ear, make sure no hair gets between the two parts. Tilt the audio processor onto the adapter from behind the ear. For optimal hearing, make sure the audio processor does not touch the outer ear. To disconnect the audio processor, press down on the side closest to the ear. Tilt the audio processor off the adhesive adapter. Do not pull on the audio processor. This may dislodge the adhesive adapter from the skin. The adhesive adapter can usually be worn day and night and should be changed once or twice a week. Remove the adhesive adapter by slowly peeling it off the skin. The adhesive adapter can only be used once. The retention clip can be connected to the audio processor with a loop. It is recommended during sport, play, or in other situations where there is a risk of the device falling off. The clip can be attached to clothing.
