3 How to wear Put on the hearing aids Check your fit
3 How to wear Put on the hearing aids TIPS: • If you have long hair, put your hair up. • If you wear glasses, keep your glasses on. • Consider using a mirror to check your fit. Step 1: Compare the left and right hearing aids. The left hearing aid has a blue receiver, and the right hearing aid has a red receiver. Step 2: Place the right hearing aid on your right ear. The hearing aid body should sit near the top of your ear. The curved section of receiver wire should wrap around the front of your ear.
How to wear 3 TIP: If you wear glasses, place the hearing aid between your glasses and your ear. Step 3: Hold the hearing aid by the bend in the receiver wire close to the dome. Step 4: Fully insert the dome into your ear canal until the receiver wire is flat against your ear and the dome feels secure. Do not insert it past this point.
3 How to wear Note: The dome may feel strange or itchy inside your ear canal at first. If you’re uncomfortable, check whether your dome size is correct (see page 36). Step 5: Check to make sure that all parts of the receiver wire run close to the side of your head. Step 6: Repeat steps 2 – 5 for the left hearing aid. Step 7: Check your fit (see page 35).
How to wear 3 To remove the hearing aids Hold the receiver wire close to the dome and gently remove the dome from your ear canal. Then, pull the hearing aid body out from behind your ear. Check your fit Use a mirror to make sure that the hearing aids are on correctly and that they fit your ears properly. Are the hearing aids on correctly? Correct: • The hearing aid body is behind your ear. • The dome is deep in your ear canal. • If you look straight in a mirror, you can’t see the dome or receiver.
3 How to wear Is the dome size correct for each ear? The size of the dome affects comfort and stability. Correct size: • The dome feels secure, though it may feel strange at first (see “Adjusting to the hearing aids” on page 54). • If you shake your head and open your mouth, the dome feels comfortable and doesn’t move. If the dome feels uncomfortable or loose: Check whether the dome is too big or too small (see page 92). If it is, you can replace it with a different size.
How to wear 3 Note: Don’t try to modify the shape of the receiver wire to force the hearing aid to fit. Correct size: • If you shake your head, the hearing aid body feels secure. • The receiver wire runs close to the side of your head. • The hearing aid body sits near the top of your ear. If the hearing aid body feels loose or the receiver wire feels tight: Check whether the receiver wire is too long or too short (see page 98). If it is, you can order a free replacement.

10 Troubleshooting Try another dome size If the domes don’t feel comfortable or secure, choose another dome size. Note: You may need to try all three dome sizes or use a d ifferent size dome for each ear. Step 1: Based on the sizing information on page 36, if the default size 2 domes are too big, try size 1. If they’re too small, try size 3 (see page 93). Step 2: From the dome packaging, select the pair of domes that matches your current dome type (see page 95). Step 3: Change the domes (see page 96).
Troubleshooting 10 Dome types Within each dome size, there are two types of domes: open and closed. Open domes (attached to the hearing aids) help your voice sound more natural. They have holes around Lorem ipsum the center of the dome. Closed domes provide more bass and allow you to comfortably use a higher World Volume setting. Try another dome type Lorem ipsum During first-time setup, use the default open domes and focus on finding the correct size for each ear.
10 Troubleshooting Change the domes Step 1: Hold the receiver and firmly pull the current dome off. Step 2: Choose a new dome size (see page 94) and/or dome type (see page 95). Note: Each dome can work with either the left or right hearing aid. Step 3: Align the opening of the new dome with the receiver and slide the dome firmly onto the receiver until it fits tightly against the ridge of the receiver. There should be no gap between the opening of the new dome and the ridge of the receiver.
Troubleshooting 10 Step 4: Gently tug the dome to make sure that it’s securely fastened on the receiver. Note: Don’t wear the hearing aid if the dome isn’t secure. Otherwise, the dome could become stuck in your ear canal (see page 88). Step 5: Repeat steps 1 – 4 for the other hearing aid, if necessary. Step 6: Put on the hearing aids (see page 32). Step 7: Check your fit (see page 35).
10 Troubleshooting Receiver wire size troubleshooting Check if the receiver wires are too long or too short If one or both receiver wires match the descriptions below, use the provided receiver wire sizing tool to measure your exact size (see page 100). If you need a different size, you can order a free replacement. Too long: • The receiver wire bends away from your head or hangs above your ear. • The hearing aid body sits far back behind your ear or feels loose.
Troubleshooting 10 Too short: The receiver wire feels tight or pulls the dome partially out of your ear canal. • If you look straight in a mirror, you see the hearing aid body over the top of your ear. Correct size: • If you shake your head, the hearing aid body feels secure. • The receiver wire runs close to the side of your head. • The hearing aid body sits near the top of your ear.
10 Troubleshooting Measure your receiver wire size Step 1: Ask a friend or family member to help (recommended). They can make things easier by checking that the receiver wire sizing tool is on your ear correctly and taking a photo for you. Note: If nobody’s around to help, you can use a mirror to check the receiver wire sizing tool and use your phone camera to take a photo. Step 2: Locate the receiver wire sizing tool provided in the box.
10 Troubleshooting Step 3: Compare the red and blue sides of the tool. Use the red side to measure your right ear and the blue side to measure your left ear. L R 1 1 2 2 3 3 Step 4: Place the tool on your right ear. It should hook around the front of your ear and lie flat against the side of your head. R Dotted line 1 2 3 Make sure that the dotted line near the top of the tool is level and aligned with the top of your ear.
10 Troubleshooting Step 5: Ask a friend or family member to take a photo of your ear. Make sure that you can see your ear canal in the photo. Note: If you’re taking the photo yourself, rest your elbow on a surface and hold your phone facing you. Position yourself so that you can see your face in your phone’s front-facing camera display. Then, turn your head and take a photo of your ear.
10 Troubleshooting Step 6: Look at the photo and see which colored band aligns with the top of your ear canal. The number in the band is the receiver wire size you need.
10 Troubleshooting Step 7: Repeat steps 4 – 6 for your left ear. L 1 Note: 2 3 You may need a different receiver wire size for each ear. Step 8: Compare your measurements for each ear. • If you need size 2: Size 2 receiver wires come attached to the hearing aids, so you already have the correct size for that ear. • If you need size 1 or 3: Order a replacement receiver wire through the Lexie Contact Center.
