Refer to Module Block diagram 4 Meet the antenna requirements of Section 15.203 Refer to external photos. 5 Be tested in a stand-alone configuration, i.e., the antenna, AC or DC power and data input/output lines must be connected to the module but, the module must not be inside another case during testing Device was tested on a supplied developmen t platform for single modular approval. Refer to setup photos. 6 Be labeled with its own FCC ID number, and if the FCC ID is not visible when the module is installed inside another device, then the out side of the device into which the module is installed must also display a label referring to the enclosed module Label is to be placed in Front of the EUT(UNTLM2471-EM), and other label is to be placed in the User’s Guide. Refer to FCC ID label format. 7 The modular transmitter is manufactured so t hat the user cannot influence the operation of the transmitter that will operate outsi de of the scope of the regulations. Refer to “User’s Guide” 8 Address compliance with the Commission’s RF exposure limits in Sections 1.1310 and 2.1091. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF exposure compliance in accordance with Section 15.247(b)(4). This device is categorically excluded from routine environmental because it operate at very low power level

ATTACHMENT FCC ID: UNTLM2471-EM ** MPE Calculations for Zigbee (2.4GHz) ** **2.4GHz Bands Worst Case of Zigbee The EUT will only be used with a separation of 20 centimeters or greater between the antenna and the body of the user. The MPE calculation for this exposure is shown below. The peak radiated output power (EIRP) is calculated as follows: EIRP = P + G EIRP = 11.75 dBm +2.5 dBi EIRP = 14.25 dBm Where, P = Power input to the antenna (mW) G = Power gain of the antenna (dBi) Power density at the specific separation: S = PG/(4R 2 π) Where, S = Maximum power density (mW/cm 2 ) P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) S = (14.96* 0.60) / (4 * 20 2 * π) S = 0.0018 mW/cm 2 The Maximum permissible exposure (MPE) for the general population is 1 mW/cm 2 . The power density at 20cm does not exceed the 1 mW /cm 2 limit. Therefore, the exposure condition is compliant with FCC rules. Estimated safe separation: R = √(PG / 4π) Where, P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) R = √(14.96* 0.60/ 4π) R = 0.845 cm The numeric gain(G) of the antenna with a gain specified in dB is determined by: G = Log -1 (dB antenna gain / 10) G = Log-1 (2.5 / 10) G = 0.60
