              by independent scientific organizations through periodic and thorough evaluation
              of scientific studies. The standards include a substantial safety margin designed to
              assure the safety of all persons, regardless of age and health. The exposure standard
              for wireless mobile phones employs a unit of measurement known as the Specific
              Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg. * Tests for SAR are
              conducted with the phone transmitting at its highest certified power level in all tested
              frequency bands. Although the SAR is determined at the highest certified power level,
              the actual SAR level of the phone while operating can be well below the maximum
              value. This is because the phone is designed to operate at multiple power levels so
              as to use only the power required to reach the network. In general, the closer you
              are to a wireless base station antenna, the lower the power output. Before a phone
              model is available for sale to the public, it must be tested and certified to the FCC that
              it does not exceed the limit established by the government adopted requirement for
              safe exposure. The tests are performed in positions and locations (e.g., at the ear and
              worn on the body) as required by the FCC for each model. The highest SAR value for
              this model phone when tested for use at the ear is 0.766W/Kg and when worn on the
              body, as described in this user guide, is 0.791W/Kg(Body-worn measurements differ
              among phone models, depending upon available accessories and FCC requirements).

            The maximum scaled SAR in hotspot mode is 0.791W/Kg. While there may be
            differences between the SAR levels of various phones and at various positions, they
            all meet the government requirement for safe exposure. The FCC has granted an
            Equipment Authorization for this model phone with all reported SAR levels evaluated
            as in compliance with the FCC RFexposure guidelines. SAR information on this model
            phone is on file with the FCC and can be found under the Display Grant section of
   oet/fccid after searching on

            FCC ID: 2ADINA6LG Additional information on Specific Absorption Rates (SAR) can
            be found on the Cellular Telecommunications Industry Asso-ciation (CTIA) web-site
            at * In the United States and Canada, the SAR limit for
            mobile phones used by the public is 1.6 watts/kg (W/kg) averaged over one gram
            of tissue. The standard incorporates a sub-stantial margin of safety to give additional
            protection for the public and to account for any variations in measurements.

            Body Worn Operation
            This device was tested for typical body-worn operations. To comply with RF exposure
            requirements, a minimum separation distance of 10mm must be maintained between
            the user’s body and the handset, including the antenna. Third-party belt-clips,
            holsters, and similar accessories used by this device should not contain any metallic
            components. Body-worn accessories that do not meet these requirements may not
            comply with RF exposure requirements and should be avoided. Use only the supplied
            or an approved antenna.

            Hearing aid compatibility (HAC) regulations for mobile phones
            In 2003, the FCC adopted rules to make digital wireless telephones compatible with
            hearing aids and cochlear implants. Although analog wireless phones do not usually
            cause interference with hearing aids or cochlear implants, digital wireless phones
            sometimes do because of electromagnetic energy emitted by the phone’s antenna,
            backlight, or other components. Your phone is compliant with FCC HAC regulations
            (ANSI C63.19- 2011).

            While some wireless phones are used near some hearing devices (hearing aids and
            cochlear implants), users may detect a buzzing, humming, or whining noise. Some
            hearing devices are more immune than others to this interference noise and phones
            also vary in the amount of interference they generate. The wireless telephone industry
            has developed a rating system for wireless phones to assist hearing device users in
            finding phones that may be compatible with their hearing devices. Not all phones have
            been rated. Phones that are rated have the rating on their box or a label located on
            the box. These ratings are not guaranteed. Results will vary, depending on the level of
            immunity of your hearing device and the degree of your hearing loss. If your hearing
            device happens to be vulnerable to interference, you may not be able to use a rated
            phone successfully. Trying out the phone with your hearing device is the best way to
            evaluate it for your personal needs.

            This phone has been tested and rated for use with hearing aids for some of the
            wireless technologies that it uses. However, there may be some newer wireless
            technologies used in this phone that have not been tested yet for use with hearing
            aids. It is important to try the different features of this phone thoroughly and in different
            locations, using your hearing aid or cochlear implant, to determine if you hear any
            interfering noise. Consult your service provider or the manufacturer of this phone
            for information on hearing aid compatibility. If you have questions about return or
            exchange policies, consult your service provider or phone retailer.

            M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to
            generate less interference to hearing devices than phones that are not labeled. M4 is
            the better/higher of the two ratings.

              T-Ratings: Phones rated T3 or T4 meet FCC requirements and are likely to be more
              usable with a hearing device’s telecoil (“T Switch” or “Telephone Switch”) than unrated
              phones. T4 is the better/higher of the two ratings. (Note that not all hearing devices
              contain telecoils.)

              Your LTE Smart phone A6L-G/A6LG has been tested for hearing aid device
              compatibility and has an M4/T3 rating.

              Hearing devices may also be measured for immunity to this type of interference. Your
              hearing device manufacturer or hearing health professional may help you find results
              for your hearing device.
