https://support.hiorka.com. 41 Taking Your First Orka Step 42 The beginning of a new hearing journey Yes! Its finally happening! That's the first thought that pops up in every user's mind when they get their hands on the brand new AI DeNoise hearing aids. Well, outstanding hearing aids may completely change your world. Everything automatically sounds better. Once the hearing sensation improves, the environment around you sounds vibrant, fun, and lively. All these feelings can be overwhelming. Hearing so many sounds clearly after a while may be too much to comprehend. But it's okay. Even though it might take a while to adapt to your new set of hearing aids fully, youll finally get the hang of it. After you fully adjust to your hearing aids, you'll never go a day without your hearing buddies!
43 What to expect in the first few weeks The first days are always the hardest. As you get started with your Orka One hearing aids, you'll notice some changes in the sounds received in your ears. That's why we thought it would be best to let you know what to expect. Before using hearing aids, you may be hearing muffles or not able to distinctively pick up sounds, depending on the severity of your hearing loss. First, there are a lot of adjustments your brain and ears need to get accustomed to. If you were not using hearing aids before, this means your ears weren't used to continually holding a device. Therefore, at first, it might be uncomfortable. We recommend a remote fitting appointment with a hearing care professional at Orka via the Orka app or through our official website at www.hiorka.com. The brain also has to start processing sound sensations and auditory stimuli. Remember, this is something that your brain has to learn doing once again, especially if it's been a while since you heard a range of sound. 44 Why is it so loud?
It's okay...it will get loud. Your hearing aids are bound to pick up sounds which you may have never heard before distinctively. Let's say, even though the sound of crunching crisps is not a new thing, it may sound louder. That's why we always advise our users to keep the volume low when wearing your hearing aids for the first time. As mentioned earlier, your brain will take some time before it gets adjusted to the new high-fidelity sounds. The adjustments won't happen overnight. It might take days or weeks, but eventually, you'll be well adjusted. Just be patient and trust the process. For the first two to four weeks, you'll be hearing a lot of unfamiliar sounds. Your voice may sound a little different. This is known as the occlusion effect. During the familiarization phase, you can start by using your hearing aids indoors, for instance, watching TV, listening to the music as you learn how to increase or reduce the hearing aids volume to suit your needs. You may also opt to wear the hearing aids only for a while. As time goes by, start increasing the length of time you use your hearing aids. Before you know it, you'll be comfortable and regularly using hearing aids. Therefore, before you fully get accustomed to your new life, kindly keep the volume low. Remember, the sound coming in should sound clear, not loud. 45 Learning your device inside out When your Orka hearing aids arrive, there will be the actual device and accessories. Accessories include the charging case, charging cable, wax guard, power adapter, etc. Everything in the package serves unique purposes. This is where the concept of learning your hearing aid comes into play. You have to learn how to correctly insert and remove the hearing aids, maintain and clean it to keep the device in excellent condition for long. There are several dos and don'ts. Therefore, please make sure to read the user guide thoroughly before using the device. We understand that a product manual is often dull, detailed, and the excitement of trying on your new device may thin your reading patience even further. But, kindly find the time, before using the device, to familiarize yourself with the user guide. You can also seek an audiologist to help guide you on using and adjusting your hearing aid settings. Remember, if you have any inquiries or need clarification on your hearing aids, always seek professional help from the Orka support team or an audiologist near you. 46 Conversations are about to get better Say goodbye to the hassle of holding and maintaining conversations in noisy places. Once you start adjusting to the new sounds from your environments and getting accustomed to the Orka hearing aids, your ability to understand speech will significantly improve. The best part is, your speech understanding will only get better over time. Since the device amplifies human voices in real-life, you'll be able to understand your friends and family even outside!
Understanding conversations better doesn't happen immediately, you just need to get adapted to your hearing aids step by step. It is essential to be very patient and continuously practice using your hearing aids. If your family and friends encouraged you to get hearing aids or are supportive, ask them to help you. Tell them to hold more conversations around you and talk slowly. Be honest and open with them. If they are talking too loud or too fast, let them know. 47 The final step After learning how to clean, maintain, and get fully adjusted to using your hearing aids in the house where it's less noisy, try wearing it in places with many background noises like restaurants. Use the settings to filter out the background noises to see if you can hold a conversation with the person right in front of you without getting distractions. We call this the final step because once you successfully pass this stage, you're able to use your hearing aids anywhere, anytime conveniently. And we believe it is the ultimate end goal!
48 Main takeaways Remember:
It takes training, patience, and time to adjust to your hearing aids fully. Carefully and thoroughly read the user guide before using your hearing aids. Keep the volume low when using the hearing aids for the first time. Cleaning and properly maintaining your hearing aids will make them last longer. Practice often with your family, friends, or the people around you. When training your hearing, start using hearings aids for a short time and increase the time length as you progress. The world will be loud for the first couple of hours. If you experience any problems adjusting to your hearing aids, get in touch with our audiologists or Orka support team, and we will gladly help you out. 49 Safety Information 50 To avoid possible personal injury or property damage caused by electric shock, high temperature, fire, radiation, explosion, mechanical hazards, and improper use, please read and observe the following items before using this product:

If it happens, it is strongly recommended to see a physician for safe removal. To avoid pushing the dome towards the eardrum, never re-insert the speaker into the ear canal. Keep the wireless hearing aids at least 15 cm (6 inches) away from the active implant. If you experience any interferences, do not use the wireless hearing aids and contact the active implant manufacturer. Please note that interferences can also be caused by power lines, electrostatic discharge, and airport metal detectors, etc. When going for special medical activities, including X-ray, CT scan, MRI/NMRI scan, etc, please remove the hearing aids in advance and place it outside the medical room. Electromagnetic radiation may affect the normal function of the hearing aids. They should be shipped per all the rules and regulations on the safe shipment of lithium-ion batteries.

Manufacturer Date of manufacture 64 Important notices Warning to hearing aid dispensers A hearing aid dispenser should advise a prospective hearing aid user to consult promptly with a licensed physician (preferably an ear specialist) before dispensing a hearing aid if the hearing aid dispenser determines through inquiry, actual observation, or review of any other available information concerning the prospective user, that the prospective user has any of the following conditions:
(i) Visible congenital or traumatic deformity of the ear.
(ii) History of active drainage from the ear within the previous 90 days.
(iii) History of sudden or rapidly progressive hearing loss within the previous 90 days.
(iv) Acute or chronic dizziness.
(v) Unilateral hearing loss of sudden or recent onset within the previous 90 days.
(vi) Audiometric air-bone gap equal to or greater than 15 decibels at 500 hertz (Hz), 1,000 Hz, and 2,000 Hz.
(vii) Visible evidence of significant cerumen accumulation or a foreign body in the ear canal.
(viii) Pain or discomfort in the ear. Children with hearing loss In addition to seeing a physician for a medical evaluation, a child with a hearing loss should be directed to an audiologist for evaluation and rehabilitation since hearing loss may cause problems in language development and the educational and social growth of a child. An audiologist is qualified by training and experience to assist in the evaluation and rehabilitation of a child with a hearing loss. 65 Important notice for prospective hearing aid users Good health practice requires that a person with a hearing loss have a medical evaluation by a licensed physician (preferably a physician who specializes in diseases of the ear) before purchasing a hearing aid. Licensed physicians who specialize in diseases of the ear are often referred to as otolaryngologists, otologists or otorhinolaryngologists. The purpose of medical evaluation is to assure that all medically treatable conditions that may affect hearing are identified and treated before the hearing aid is purchased. Following the medical evaluation, the physician will give you a written statement that states that your hearing loss has been medically evaluated and that you may be considered a candidate for a hearing aid. The physician will refer you to an audiologist or a hearing aid dispenser, as appropriate, for a hearing aid evaluation. The audiologist or hearing aid dispenser will conduct a hearing aid evaluation to assess your ability to hear with and without a hearing aid. The hearing aid evaluation will enable the audiologist or dispenser to select and fit a hearing aid to your individual needs. If you have reservations about your ability to adapt to amplification, you should inquire about the availability of a trial-rental or purchase-option program. Many hearing aid dispensers now offer programs that permit you to wear a hearing aid for a period of time for a nominal fee after which you may decide if you want to purchase the hearing aid. Federal law restricts the sale of hearing aids to those individuals who have obtained a medical evaluation from a licensed physician. 66 Federal law permits a fully informed adult to sign a waiver statement declining the medical evaluation for religious or personal beliefs that preclude consultation with a physician. The exercise of such a waiver is not in your best health interest and its use is strongly discouraged. Additional notices A hearing aid will not restore normal hearing and will not prevent or improve a hearing impairment resulting from organic conditions. In most cases infrequent use of a hearing aid does not permit a user to attain full benefit from it. Service and warranty Orka One offers a 2-year limited warranty and a 45-day free trial period valid from the date you receive the product. This limited warranty covers manufacturing and material defects in the hearing aids and charging case, but does not cover accessories including tubes, domes, and external receivers respectively. The warranty does not affect any legal rights that you might have under applicable national legislation governing sale of consumer goods. Users are not covered by the warranty if one of the following occurs:
