If you feel pain in or behind your ear, if it is inflamed, if skin irritation or accumulations of ear wax occur, please check with your hearing healthcare provider or physician. Hearing programs in the directional microphone mode reduce background noises. Please be aware that warning signals or noises coming from behind, e.g. cars, are partially or entirely suppressed.
Caution: You might need medical help if a piece gets stuck in your ear. If any part of your hearing aid, like the eartip, gets stuck in your ear, and you can’t easily remove it with your fingers, get medical help as soon as you can. You should not try to use tweezers or cotton swabs because they can push the part farther into your ear, injuring your eardrum or ear canal, possibly seriously. Note: If you remain concerned, consult with a professional.
Note: Tell FDA about injuries, malfunctions, or other adverse events. To report a problem involving your hearing aid, you should submit information to FDA as soon as possible after the problem. FDA calls them “adverse events,” and they might include: skin irritation in your ear, injury from the device (like cuts or scratches, or burns from an overheated battery), pieces of the device getting stuck in your ear, suddenly worsening hearing loss from using the device, etc.

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. L R Step 2: Place the right hearing aid on your right ear. The hearing aid body should sit near the top of your ear.
3 How to wear 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. 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 37).
How to wear 3 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 36). 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.
3 How to wear 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.
How to wear 3 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 49). • 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 83). If it is, you can replace it with a different size.
3 How to wear Is the receiver wire size correct for each ear? The size of the receiver wire determines the position and a ngle of the hearing aid behind your ear. This affects audio p erformance, comfort, and stability. The provided receiver wires will fit most ears. However, you might need longer or shorter receiver wires or a different size for each ear. Note: Don’t try to modify the shape of the receiver wire to force the hearing aid to fit.

5 Adjusting to the hearing aids What to expect
5 Adjusting to the hearing aids What to expect Adjusting to a new hearing aid can feel overwhelming at first, and it can take time to feel fully comfortable. With patience, though, you’ll soon be enjoying better hearing. Here’s what you can expect during the first few days and weeks of using the hearing aids. Comfort and fit • The domes may feel strange or itchy inside your ear canal at first. This is normal, and you’ll get used to the feeling over time.
5 Adjusting to the hearing aids Adjusting to new sounds • Sounds may seem loud or different. You may also notice background noises that you haven’t heard before. As your brain learns to recognize and filter out these sounds, they’ll become less apparent over time. TIP: Wear the hearing aids as much as possible to become more quickly accustomed to new sounds. • Your voice may seem loud at first.

Hearing aids whistle Choose another dome size (see page 85). You may need a different size for each ear. If you’re using open domes, try replacing them with the same size closed domes (see page 86). Decrease World Volume (see page 41).
9 Troubleshooting Problem Solutions On your phone, increase the volume. If you’re in private, turn on speaker phone and hold your phone in front of you. Can’t hear phone call Make sure you’re not pressing your phone too hard against your ear. This can block the hearing aid microphones and cause the call to sound muffled. Try holding your phone so that the phone receiver is slightly above and behind your ear. This puts it closer to the hearing aid microphones.
Troubleshooting Problem Solutions Hearing aids whistle when on the phone Tilt your phone receiver slightly away from the hearing aid on that ear. Hearing aids sound different from each other Adjust World Volume (see page 41). This syncs audio settings between the hearing aids.
9 Troubleshooting Problem Sound of own voice is too loud Solutions Practice listening to new sounds and talking with a friend in a familiar environment before you use the hearing aids for conversation (see page 51). If you’re using closed domes, try replacing them with the same size open domes (see page 86). Consider adjusting the treble or bass on your app to see if any improvement is perceived.
Troubleshooting 9 Dome troubleshooting Check if the domes are too big or too small If one or both domes match the descriptions below, try a different dome size (see page 84). Too big: • The dome feels painful or uncomfortable. • It’s difficult to insert the dome into your ear canal. • The bend in the receiver wire close to the dome doesn’t sit flat against your ear. Too small: • The dome feels loose or insecure. • If you shake your head and open your mouth, the dome feels painful or moves.
9 Troubleshooting Dome sizes The dome size is marked on the dome packaging as size 1, size 2, or size 3. SIZE 1 SIZE 2 SIZE 3 Size 2 open domes come attached to the hearing aids. Note: Dome size doesn’t relate to receiver wire length. You might have a different dome size and receiver wire size for the same hearing aid.
Troubleshooting 9 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 different size dome for each ear. Step 1: Based on the sizing information on page 84, if the default size 2 domes are too big, try size 1. If they’re too small, try size 3. Step 2: From the dome packaging, select the pair of domes that matches your current dome type (see page 86). Step 3: Change the domes (see page 87).
9 Troubleshooting 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 the center of the dome. Closed domes provide more bass and allow you to c omfortably use a higher World Volume setting. Try another dome type During first-time setup, use the default open domes and focus on finding the correct size for each ear.
Troubleshooting 9 Change the domes Step 1: Hold the receiver and firmly pull the current dome off. Step 2: Choose a new dome size (see page 85) and/or dome type (see page 86). Note: Each dome can work with either the left or right h earing 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.
9 Troubleshooting 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 78). Step 5: Repeat steps 1 – 4 for the other hearing aid, if necessary. Step 6: Put on the hearing aids (see page 33). Step 7: Check your fit (see page 36).
Troubleshooting 9 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 91). 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.
9 Troubleshooting 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.
9 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.
9 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. 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. Make sure that the dotted line near the top of the tool is level and aligned with the top of your ear.
9 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 Ear canal hoto yourself, rest your p 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.
9 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.
9 Troubleshooting Step 7: Repeat steps 4 – 6 for your left ear. Note: 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.
