2ADKJ-EXT1PROCESSOR UNIT

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. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television 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 Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. RF Exposure Warning Statements: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment shall be installed and operated with minimum distance 20cm between the radiator & body. This device is acting as slave and operating in the 2.4 GHz (2412 ~2462 MHz) band. Ad Hoc function is supported but not able to operate on non-US frequencies. Operation of this device is restricted to indoor use only.(5GWIFI)

RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description PROCESSOR UNIT Model Name XP-EXT1P FCC ID 2ADKJ-EXT1 2. EVALUATION METHOD Human exposure to RF emissions from mobile devices (47 CFR §2.1091) may be evaluated based on the MPE limits adopted by the FCC for electric and magnetic field strength and/or power density, as appropriate, since exposures are assumed to occur at distances of 20 cm or more from persons. LIMITS FOR GENERAL POPULATION / UNCONTROLLED EXPOSURE Frequency Range (MHz) E-field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) (mW/cm 2 ) Averaging Time |E| 2 , |H| 2 or S (Minutes) 0.3 -- 1.34 614 1.63 (100)* 30 1.34 -- 30 824/f 2.19/f (180/f 2 )* 30 30 -- 300 27.5 0.073 0.2 30 300 -- 1500 -- -- f/1500 30 1500 -- 100,000 -- -- 1.0 30 *Note: 1. f= Frequency in MHz * Plane-wave Equivalent Power Density 2. The averaging time for General Population/Uncontrolled exposure to fixed transmitters is not applicable for mobile and portable transmitters. See 47 CFR §§2.1091 and 2.1093 on source-based time-averaging requirement for mobile and portable transmitters. S=PG/4πR² Where: S=power density P=power input to antenna G=power gain of the antenna in the direction of interest relative to an isotropic radiator R=distance to the center of radiation of the antenna 3. CALCULATION A minimum test separation distance ≥ 20 cm is required between the antenna and radiating structures of the device and nearby persons to apply mobile device exposure limits. The distance must be at least 20 cm and fully supported by the operating and installation configurations of the transmitter and its antenna(s), according to the source-based time-averaged maximum power requirements of § 2.1091(d)(2). In cases where cable losses or other attenuations are applied to determine compliance, the most conservative operating configurations and exposure conditions must be evaluated. BR/EDR: Antenna Gain=2dBi (Numeric 1.58), π=3.14 BLE: Antenna Gain=2dBi (Numeric 1.58), π=3.14 2.4GHz Wi-Fi： Antenna Gain=2dBi (Numeric 1.58), π=3.14 Frequency Output Power Output Power Power Density Power Density Limit MHz dBm mW mW/cm 2 mW/cm 2 2480 -0.051 0.99 0.000099 1 Frequency Output Power Output Power Power Density Power Density Limit MHz dBm mW mW/cm 2 mW/cm 2 2480 -0.375 0.92 0.000092 1 Frequency Output Power Output Power Power Density Power Density Limit MHz dBm mW mW/cm 2 mW/cm 2 2412 9.54 8.99 0.002827 1 5GHz Wi-Fi： Antenna Gain=2dBi (Numeric 1.58), π=3.14 Simultaneously transmitting (worst case is BR/EDR+2.4GHz Wi-Fi)=0.000099+0.002827=0.002926<1 Note: Only the worst case recorded. 4.
