Omni OTC Hearing Aids User Guide Warnings This OTC hearing aid is for users who are 18 and older. People who are younger than 18 with hearing loss should see a doctor, preferably an ENT, because they may need medical testing and management. Hearing loss can affect speech and learning, so professional fitting and continuing care are also important. Warning: When to see a doctor • If you have any of the problems listed below, please see a doctor, preferably an ear-nose-throat doctor (an ENT). • Your ear has a birth defect or an unusual shape. Your ear was injured or deformed in an accident. Warning: If you are younger than 18, do not use this. You should go to a doctor, preferably an ear-nose-throat doctor (an ENT), because your condition needs specialized care. Over-the-counter hearing aids are only for users who are age 18 or older. • You saw blood, pus, or fluid coming out of your ear in the past 6 months • You have a lot of ear wax, or you think something could be in your ear • You get really dizzy or have a feeling of spinning or swaying (called vertigo) • Your hearing changed suddenly in the past 6 months • Your hearing changes: it gets worse then gets better again • You have worse hearing in one ear • You hear ringing or buzzing in only one ear Warning: This hearing aid should not cause pain when inserting it. • Remove this device from your ear if it causes pain or discomfort when you insert or place it. To try again, make sure to follow the instructions. If you feel pain or discomfort again, contact the manufacturer. If your pain or discomfort doesn't go away, contact your hearing healthcare professional. You can also report this to FDA as an adverse event according to the instructions that appear later. Warnings: • Keep and store hearing aids and components out of reach of children. Contains small parts which may be a choking hazard. • Check before using the hearing aids in areas where electronics or wireless devices are restricted. This may cause interference. • Do NOT dry hearing aid with a hairdryer. Heat may damage hearing aid. • Do NOT use the hearing aids without the supplied dome attached. • Do NOT use the hearing aids in explosive or oxygen- enriched atmospheres. Otherwise, a fire or explosion could occur. • Do NOT resell the hearing aids or share them with others. They are intended for use by a single user. Using resold or shared hearing aids may lead to infection. • Do NOT submerge in water, wear in the shower, or wear while participating in water sports, e.g., swimming, waterskiing, surfing, etc. Prolonged exposure to water may damage the hearing aids. • Do NOT repair or replace the lithium-ion rechargeable battery yourself. Contact us if you believe a battery replacement is required. • Do NOT wear hearing aids while sleeping. • Do NOT use hearing aids during X-rays, MRIs, CT scans or other similar medical treatment to prevent damage to the hearing aid. • Do NOT expose hearing aid to contaminants such as hair spray, mousse, gel, lotions, etc. to prevent damage to the hearing aid. • Do NOT use an instrument, such as a cotton swab, to push the hearing aid in the ear canal. Hearing aids may be placed too deep and cause damage to the ear. • Do NOT place charging case in clothing pocket while charging with the USB power cable. The charging case may overheat and malfunction. Cautions 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. 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. Caution: You might need medical help if a piece gets stuck in your ear. If any part of your hearing aid, like the dome, 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 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 Notes out of using hearing aids in both, especially in situations that make you tired from listening-for example, noisy environments. 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. Cautions: • Do NOT use the hearing aids or their components if any part of them is…
