FCC Statement: This device complies with part 15 of the FCC Rules. Operation i s subject to t he following tw o 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. 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 guarant ee 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. Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environm ent. This transmitter must not be co‐located or operating in conjunction with any other antenna or transmitter.

Standalone SAR test exclusion considerations Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Exclusion Threshold condition, listed below, is satisfied. 2.1.2 Limits 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 calculation17 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 Report No.: MTEB24070063-H Page 5 of 5 2.1.3 EUT RF Exposure EIRP =PT*GT= (E x D)²/30 where: PT = transmitter output power in watts, GT = numeric gain of the transmitting antenna (unitless), E = electric field strength in V/m, ---10 (dBμV/m)/20) /10 6 , D = measurement distance in meters (m)---3m, So PT = (E x D)²/30 / GT The worst case (refer to report MTEB24070063-R) is below: Antenna polarization: Horizontal Frequency (MHz) Level (dBuV/m) Polarization 433.92 76.09 Peak 433.92 50.29 Average Antenna polarization: Vertical Frequency (MHz) Level (dBuV/m) Polarization 433.92 75.32 Peak 433.92 51.1 Average For 433.92MHz wireless: Field strength=76.09dBuV/m Ant gain 3dBi;so Ant numeric gain=2 EIRP = PT*GT = (E x D)²/30=(10 (dBμV/m)/20) /10 6 *3) 2 /30=0.000012 So PT= EIRP/GT=0.000012W=0.012mW So(0.012mW/5mm)* √0.43392GHz=0.0016 exclusion=0.0016<3.0 for 1-g SAR So the SAR report is not required.
