PREMIUM IN-THE-EAR OTC HEARING AIDS Android or iOS device compatible but not required for use TALA ™ 1 Welcome Aboard! We’re honored you’ve chosen to be a part of the Lucid Hearing™ family! Our commitment to you is simple: To help you hear better! Your journey to better hearing begins now. Every successful journey has a guide to help you get the most out of the adventure! There are two key guides at your disposal. This booklet is a quick and easy reference for you to get started. And for additional details and information, be sure to check out our “how to” video series at lucidhearing.com! Let’s get started! WARNING: If you are younger than 18, do not use this. You should talk 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. 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. 23 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, puss, 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 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. 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. 45 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 ear tip, 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 out of using hearing aids in both, especially 67 CONTENTS Quick Start Guide .........................................................................................8 Getting to Know Tala™ ............................................................................10 What’s Inside .................................................................................................11 Getting to Know Tala™ Charging Case...........................................12 Charging Tala™ ............................................................................................13 Charging Lights ...........................................................................................14 Wearing Your New Hearing Aids ........................................................15 Download the Lucid Hearing App .....................................................16 How to Adjust Volume and Programs .............................................17 Start-Up and Pairing ........................................................................18-19 Care and Cleaning Instructions ...................................................20-21 How to Clean Tala™ Hearing Aids .....................................................19 Replacing Wax Stop ........................................................................22-23 Choosing the Correct Ear Tip ..............................................................24 Replacing the Ear Tips ............................................................................25 Troubleshooting .................................................................................26-27 Technical Data ............................................................................................28 Warranty ...........................................................................................…

Introduction The FCC, Innovation, Science and Economic Development Canada, European Union and Australia/New Zealand publish standards regarding the evaluation of the RF Exposure hazard of radio communications devices. An evaluation has been performed on the Etymotic Research Inc TALA Bluetooth Hearing Aids (Model No. Tala) pursuant to the relevant requirements. 3. Subject of Investigation This document presents the demonstration of RF Exposure compliance on a TALA Bluetooth Hearing Aids (hereinafter referred to as the Equipment under Test (EUT)). The EUT was identified as follows: EUT Identification Description TALA Bluetooth Hearing Aids Model/Part No. Tala Serial No. (LEFT) 003A (RIGHT) 008B (CHARGER) 005 Radio Access Technology BLE Band of Operation 2400 – 2483.5MHz EIRP -14.13dBm (0.0000386W) Antenna Gain 0dB 4. Standards and Requirements The tests were performed to selected portions of, and in accordance with the following specifications. - 47 CFR Parts 1.1307,1.1310, 2.1091 and 2.1093 Code of Federal Regulations, Title 47, Telecommunications - KDB 447498 D01 – “RF Exposure Procedures and Equipment Authorization Polices for Mobile and Portable Devices, General RF Exposure Guidance v06” - OET Bulletin 65 Edition 97-01:1997 – “Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields” - ANSI/IEEE C95.1:1992 – "Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz," - RSS-102, Issue 5 – “Radio Frequency (RF) Exposure Compliance of Radiocommunication Apparatus (All Frequency Bands)” 5. Sample Calculations The far field power density can be calculated using the following formula: = 4 (1) where P is the transmit output power (mW), G is the maximum antenna gain relative to an isotropic antenna (linear) and R is the evaluation distance (cm).
