ZRR-ZT2209Self-Tuning Hearing aids

LR L R Safety and health information Intended use The Lark Sound hearing aids are a pair of user-fitted wireless air conduction hearing aids intended for use by individuals 18 years and older with perceived mild to moderate hearing impairment. Indications for use The Lark Sound hearing aids are intended to amplify sound for individuals 18 years of age or older with perceived mild to moderate hearing impairment. They are adjusted by the user to meet the user’s hearing needs. No pre-programming or hearing test is necessary. The device is intended for direct-to-consumer sale and use without the assistance of a hearing care professional. Clinical data In a clinical study, people with mild to moderate hearing impairment generally experienced similar hearing benefit, and were more satisfied, when using the Lark Sound self-fitting technology compared with professional fitting of the same device. There were no adverse events encountered during this study. Hearing health care information This product may help you hear better if you: • Strain to follow conversations when others don’t, especially in noisy places. • Have trouble understanding the TV. 23 This product may not be right for you if you: • Consistently experience feedback (whistling) of the hearing aid when you turn up volume to a level that is comfortable for you, even after you have followed the suggestions in these Instructions for Use to make sure your hearing aid fits properly. • Feel the hearing aid is not providing enough amplification even at the highest volume setting. A hearing health care professional may be able to help you select a different hearing aid solution to meet your needs. You should see a hearing health care professional if you: • Have a visible deformity of the ear. • Have a current ear infection or a history of active discharge from one or both ears within the past 90 days. • Have sudden or rapid progression of hearing loss within the past 90 days in one or both ears. • Have acute or chronic dizziness, poor dexterity, poor vision, or significant dementia. • Suspect that you have significant ear wax accumulation or a foreign object in the ear canal. Symptoms of significant ear wax accumulation can include itching in your ear, a feeling of fullness in your ear, and/or reduced hearing. • Experience pain or discomfort in the ear. • Have a noticeable difference in hearing between ears. • Have sudden onset or rapid worsening of tinnitus (ringing in the ear) in one or both ears within the past 90 days. This product will not restore normal hearing and will not prevent or improve a hearing impairment resulting from organic conditions. This product is designed to help you make greater use of your remaining hearing ability. You should keep in mind that it can take time to become accustomed to hearing new sounds. For best results, practice using the hearing aids as much as possible. In most cases, infrequent use of the hearing aids doesn’t permit you to attain full benefit from them. The use of a hearing aid is only part of hearing habilitation and may need to be supplemented by auditory training and instruction in lipreading. It is good health practice for a person with a hearing loss to have a medical evaluation by a licensed physician (preferably a physician who 645 specializes in diseases of the ear). Licensed physicians who specialize in diseases of the ear are often referred to as otolaryngologists, otologists, or torhinolaryngologists. The purpose of a medical evaluation is to assure that all medically treatable conditions that may affect hearing are identified and treated. • Do NOT use the hearing aids in explosive or oxygen-enriched atmospheres. Otherwise, a fire or explosion could occur. • Check before using the hearing aids in areas where electronics or wireless devices are restricted. This may cause interference. • 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. • Keep the product away from fire and excessive heat (e.g., from storage in direct sunlight, near candles, or in a hot car) to avoid burns or damage to product. • 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. Keep and store device and components out of reach of children. Contains small parts which may be a choking hazard. • To prevent hearing damage: – Use appropriate hearing protection in loud environments. The hearing aids are NOT hearing protection devices. – Remove the hearing aids if you encounter any overly loud sounds. • Be aware that some sounds may sound different when you’re using the hearing aid. Keep this in mind when you need to be aware of your urroundings. You should adjust to this over time. • Consult a hearing care professional if you experience any unusual side effects like skin irritation, excessive accumulation of ear wax, dizziness, change in your hearing, or if you think there may be a foreign object in your ear canal. • When adjusting the volume/bass/treble, turn up gradually until you reach a comfortable listening level. • Do NOT use the hearing aid or their components if any part of them is damaged, if they emit any loud unusual noise, if you 879 experience a warming sensation, or if you experience loss of audio. If this happens, remove and power off the hearing aid immediately, then contact our support team via email [email protected]. • Do NOT make unauthorized alterations to this product. 101112 Typical symptoms of hearing impairment: 1. Complete hearing loss : No sound can be heard. 2. Hearing loss: Sound can be heard, but very difficult to hear clearly. 3. Hearing loss of high frequency sound: hardly to catch the high-pitched sounds like women’s voice, Can’t hear clearly when in phone call, watching TV etc. 4. Hearing loss of low frequency sound: Hardly to catch the low…
