Caution and notices for users
Caution: This is not hearing protection. You should remove this device if you experience overly loud sounds, whether short or long-lasting. If you’re in a loud place, you should use the right kind of hearing protection instead of wearing this device. In general, if you would use ear plugs in a loud place, you should remove this device and use ear plugs.
Caution: The sound output should not be uncomfortable or painful. The sound output should not be uncomfortable or painful. You should turn down the volume or remove the device if the sound output is uncomfortably loud or painful. If you consistently need to turn the volume down, you may need to further adjust your device.
6

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. If you try this device and continue to struggle with or remain concerned about your hearing, you should consult with a hearing healthcare professional.
Note: What you might expect when you start using a hearing aid. A hearing aid can benefit many people with hearing loss. However, you should know it will not restore normal hearing, and you may still have some difficulty hearing over noise. Further, a hearing aid will not prevent or improve a medical condition that causes hearing loss. People who start using hearing aids sometimes need a few weeks to get used to them. Similarly, many people find that training or counseling can help them get more out of their devices. If you have hearing loss in both ears, you might get more out of using hearing aids in both, especially in situations that make you tired from listening-for example, noisy environments.
7

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. Instructions for reporting are available at https://www.fda.gov/Safety/ MedWatch, or call 1-800-FDA-1088. You can also download a form to mail to FDA.

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.

LR

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.

33

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).
34

How to wear

3

To remove the hearing aids
Hold the receiver wire close to the dome and gently remove the dome end of the receiver wire 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.
35

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.
Is the receiver wire size correct for each ear? The size of the receiver wire determines the position and angle of the hearing aid behind your ear. This affects audio performance, 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.
36

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.

During phone calls, hold your phone to your ear like you normally would. The hearing aid microphones amplify sound from your phone speakers. Tips for clear phone calls · On your phone, increase the volume until you can
comfortably hear the call. · If you’re in a private area, turn on speaker phone and
hold your phone in front of you. · 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 or your hearing aids to whistle.

Steps to connect your hearing aids to an iPhone Your iPhone should have Bluetooth® and your hearing aids need to be paired with it. If your hearing devices aren’t listed in Settings > Accessibility > Hearing Devices, you need to pair them with your iPhone by following these steps: 1. Ensure your hearing aids are fully charged and
switched on before pairing. (see page 39 ) 2. On your iPhone, go to Settings > Bluetooth to
ensure Bluetooth is turned on. 3. On your iPhone, go to Settings > Accessibility >
Hearing Devices. 4. When the name and/or model number of your
hearing aid/s appears on the screen tap the name and respond to both pairing requests (pairing can take up to 60 seconds). 5. You will now hear your iPhone ringtone and message alerts directly through your hearing aids.

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. However, if they feel painful, try a different dome size (see page 99). · The hearing aids might feel slightly uncomfortable to start. Try to wear them as much as possible to give yourself time to get used to the feeling.
TIP: If you aren’t comfortable wearing the hearing aids all day, try wearing them for a few hours at a time and gradually work up to longer use.
58

Adjusting to the hearing aids

Adjusting to new sounds · Sounds might seem loud or different. You may also
notice background noises that you haven’t heard for a long time. 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. To help, practice talking with a friend in a familiar environment before using the hearing aids for other conversations.
· You might need to experiment with different hearing aid settings as you try the hearing aids in new environments. Over time, you’ll find settings that work for you and won’t need to adjust them as often.
TIP: Be patient! It can take some people up to several months to fully adjust to their hearing aids.

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 comfortably 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.
After using the hearing aids for some time, though, if you feel like you need more amplification or hear whistling at higher World Volume settings, consider trying closed domes.
101

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 100) and/or dome type (see page 101).
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.
