USER MANUAL CRE-C10 SONY
Self-fitting OTC hearing aids CRE-C10

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 18 or older.
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. ▶ You saw blood, pus, or fluid coming out of your ear in the past 6 months. Your ear feels painful or uncomfortable. ▶ 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 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 the 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 does not 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.

WARNING
Risk of injury!
Always wear the hearing aid with a Click Sleeve.
▶ Make sure that the Click Sleeve is completely attached. You should feel that it snaps into place. ▶ Ensure that only a single Click Sleeve is attached to each hearing aid. In the very rare case that the click sleeve gets stuck in the ear canal and you cannot remove it yourself, please contact a physician. Do not insert the Click Sleeves in your ears without the hearing aid attached.

WARNING
In case you have any doubt whether this device is appropriate for you, consult a licensed physician before using this device.

WARNING
This hearing aid is intended for you only and should not be worn by others.

NOTICE
Do not use your hearing aids while swimming or while taking a shower.

WARNING
Choking hazard!
Your hearing aids contain small parts which can be swallowed.
Keep hearing aids, batteries and accessories out of reach of children and pets. If parts have been swallowed consult a physician or hospital immediately.

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 eartip, gets stuck in your ear, and you cannot 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 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, call 1-800-FDA-1088. You can also download a form to mail to FDA.

Regulatory information
FDA identifies this generic type of device as:
Self-fitting air-conduction hearing aid.
A self-fitting air-conduction hearing aid is a wearable sound amplifying device that is intended to compensate for impaired hearing and incorporates technology, including software, that allows users to program their hearing aids.
This technology integrates user input with a self-fitting strategy and enables users to independently derive and customize their hearing aid fitting and settings.
For hearing aid users
Hearing aids will not restore normal hearing and will not prevent or improve a hearing impairment resulting from organic conditions. In most cases infrequent use of hearing aids prohibits the wearer from attaining the full benefit from it. The use of hearing aids is only part of hearing rehabilitation and may need to be supplemented by auditory training and instruction in lip reading.
Health considerations
If soreness or skin irritation develops, discontinue wearing your hearing aids.
Battery tips
If a battery is accidentally swallowed, seek medical attention immediately, or call the National Button Battery Ingestion Hotline collect at 1-800-498-8666.

Wireless security measures
Wireless signal security is assured through the device system design that includes:
- A built-in pairing table which specifies valid and legitimate pairing among units.
- A proprietary communication protocol which checks the package numbers during each transmission. ● A Cyclic Redundancy Check (CRC) to check data validity.
- A convolutional encoder/decoder (Viterbi) to correct errors.
Quality of Service (QoS) for the ear-to-ear wireless technology
Synchronization/exchange of low data rate ear-to-ear signals
Similar QoS as with remote controls in typical households. In typical environment it can happen that electromagnetic noise from appliances (light switch, car ignition) lead to non-valid data. Transmission of unsuccessful command is automatically repeated within approximately 3 seconds. Data transfer is checked via CRC16 checksum.
Exchange of high data rate ear-to-ear signals (microphone signal)
Parameter for QoS is the bit error (BER) of the gross data link. This parameter is estimated and monitored during data receive. For BER > 3.5% the channel coding will become less effective thus the transferred microphone signal is automatically muted and not used until the QoS is good enough again. For the used ITU G.722 Audio Codec CRC check is not useful.
It is reasonably foreseeable that no risk/hazard can rise caused by invalid data.
Cybersecurity
Proper set-up and operation of your hearing aids requires a safe, private and secure operating environment.
The U.S. Federal Trade Commission's guidance for online security https://consumer.ftc.gov/online-security
provides examples of best practices for securing your home network and mobile device to ensure your security.
For 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.
