Operation is subject to the following two conditions: (1) this device may not cause harmful interf erence , and (2) this device must accept any interference received,including interference that may cause undesired operation. Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. Howe ver, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or t elevision reception,which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/TV technician for help. The users manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. In cases where the manual is provided only in a form other than paper, such as on a computer disk or over the Internet, the information required by this section may be included in the manual in that alternative form, provided the user can reasonably be expected to have the capability to access information in that form. SCALE scale with damp cloth. p Scale Don't No user information is issued, and no user is identified（Turn on the Bluetooth of the mobile phone, use the mobile APP to establish a connection with the scale, and then measure again.） Multiple users identified in offline testing（During the offline test, the scale recognizes multiple users by weight, and cannot recognize a specific user parameter. Please connect to APP directly for online test） Questions? Contact Health 855-633-5600 SMART BODY SCALE INSERTING THE BATTERIES: Turn the scale over and place it on a flat surface. Open the battery cover and insert four AAA batteries. Make sure the positive and negative ends are facing the correct polarity directions marked in the battery compartment. Close the battery cover and wait until the digits "0.0" are shown on the LED display. BATTERY REPLACEMENT: In the event that the scale batteries need to be replaced (display shows “Lo”),remove the battery cover.Replace the old batteries with 4 new AAA alkaline batteries. Clean the battery contacts and also those of the device prior to battery installation. Ensure the batteries are installed correctly with regard to polarity,and the supply terminals are not to be short-circuited,then replace the battery cover again. Remove used batteries promptly. Dispose of the old batteries as per legal regulations. Do not attempt to open the scale or to remove any components. Servicing should be done by qualified technicians only.

FCC ID: 2AZ2X802B4 Portable device According to §15.247(i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to KDB447498 D01 General RF Exposure Guidance V06 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] * [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where f(GHz) is the RF channel transmit frequency in GHz； Power and distance are rounded to the nearest mW and mm before calculation； The result is rounded to one decimal place for comparison； The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. We use 5mm as separation distance to calculate. Maximum measured transmitter power: Mode Transmit Frequency (GHz) Max Conducted Power (dBm) tune up maximum power(dBm) Result calculation 1-g SAR GFSK 2.48 3.494 4.0 0.8 3 Conclusion: For the max result : 0.8 ≤ 3.0 for 1-g SAR extremity SAR, No SAR is required.
