FCC ID: IPH-05125 IC: 1792A-05125 SAR-001: SAR Test Report RevA Test Report S/N: 2025.045.01 Page E1 of E1 Appendix E: Simultaneous Transmission Analysis E.1. Introduction According to FCC KDB Publication 447498 D04v01, transmitters are considered to be operating simultaneously when there is overlapping transmission, with the exception of transmissions during network hand-offs with maximum hand-off duration less than 30 seconds. Table E-1 - Supported Simultaneous Transmission Scenarios E.2. Procedures This device contains transmitters that may operate simultaneously. Therefore, simultaneous transmission analysis is required. Per FCC KDB Publication 447498 D04v01 and IEEE 1528-2013 Section 6.3.4.1.2, simultaneous transmission SAR test exclusion may be applied when the sum of Exposure Ratio for all the simultaneous transmitting antennas in a specific physical test configuration is ≤1. E.3. Simultaneous Transmission Analysis Table E-2 – Total Exposure Ratio (TER) Please refer to report SN 2025.045.03 and 2025.045.04 for 24 GHz Radar Data The above analysis of the simultaneous transmission scenarios is sufficient to show that simultaneous transmission cases will not exceed the SAR limit. Therefore, no measured volumetric simultaneous SAR summation is required per FCC KDB Publication 447498 D04v01 and IEEE 1528- 2013 Section 6.3.4.1. #ScenarioBodyExtremity 12.4 GHz Bluetooth LE + 24 GHz RadarYesYes CertificationSub6 Exposure Sub6 Exposure Ratio 24 GHz Radar Exposure Ratio TER FCC2.4 GHz Bluetooth LEBody0.0270.3340.361 FCC2.4 GHz Bluetooth LEExtremity0.0060.3340.340 ISED2.4 GHz Bluetooth LEBody0.0270.1120.139 ISED2.4 GHz Bluetooth LEExtremity0.0060.1120.118

SAR System Check Prior to SAR assessment, the system is verified to ±10% of the SAR measurement on the reference dipole at the time of calibration by the calibration facility. SAR System Validation was performed and complies with requirements per IEC/IEEE 62209-1528. Table 1 System Check Results (SAR) B.2. Dielectric Parameters of the TSL Table 2 SAR Tissue Dielectric Parameters The above measured tissue parameters were used in the DASY software. The DASY software was used to perform interpolation to determine the dielectric parameters at the SAR test device frequencies (per KDB Publication 865664 D01v01r04 and IEEE 1528-2013 6.6.1.2). The tissue parameters listed in the SAR test plots may slightly differ from the table above due to significant digit rounding in the software. The SAR values were compensated for deviations between the measured and required tissue dielectric properties, as described in IEEE 1528-2013. The SAR values were applied to only scale up the measured SAR values, and not downward, per KDB Publication 865664 D01v04r04. System Frequency (MHz) Tissue Type Date Amb. Temp.

FCC System Validation Per FCC KDB Publication 865664 D02 Section 2.3 a) states “SAR system validation status and system verification results should be documented in a separate section of the SAR report, or as an attachment, to confirm measurement accuracy.” The SAR systems used for evaluating this device were validated against its performance specifications prior to the SAR measurements. Reference dipoles were used with the required tissue-equivalent media for system validation, according to the procedures outlined in FCC KDB Publication 865664 D01 and IEEE 1528-2013. Since SAR probe calibrations are frequency dependent, each probe calibration point was validated at a frequency within the valid frequency range of the probe calibration point. Per FCC KDB 865664 D02, “the validation status should be documented according to the validation date(s), measurement frequencies, SAR probes, calibrated signal type(s) and tissue dielectric parameters.” A tabulated summary of the system validation status is provided accordingly: Table 3 System Validation NOTE: The probes have been calibrated for both CW and modulated signals. Modulations in the table above represent test configurations for which the measurement system has been validated per FCC KDB Publication 865664 D01 for scenarios when CW probe calibrations are used with other signal types. SAR systems were additionally validated for modulated signals with a periodic duty cycle or with a high PAR (peak to average ratio) >5 dB, such as OFDM according to FCC KDB Publication 865664 D01 v01r04.

Applicant: Garmin International FCC ID: IPH-05125 Antenna Datasheet IC: 1792A-05125 Antenna Datasheet Antenna Manufacturer Information: Antenna(s) are manufactured and designed at Garmin headquarters located at 1200 E. 151 st Street, Olathe, KS, 66062, USA. Garmin is an antenna manufacturer that specializes in antenna construction and has been a technology leader in high performance antenna design for over thirty years. State-of-the art equipment is used to design, measure, and analyze new designs that are superior to competitor designs and highly proprietary in nature. Antenna Description: This data sheet contains the antenna gain information for the A05125-A1/A2 for Garmin Model A05125. The approximate operational frequency band of these technologies is given, and the maximum gain within the frequency band is shown in table 1. Table 1 Antenna Gain: Antenna Model Number Type Band (MHz) Maximum Gain (dBi) @ Frequency (MHz) A05125-A1 Patch Array 24075 – 24175 N/A A05125-A2 Inverted F 2400 – 2480 3.33 @ 2480 Additional Information: Antenna gain is listed as N/A in the table where the specific antenna is only used for radios where the applicable rule parts are measured as a radiated field strength, and/or there are no rules pertaining to antenna gain limits. As all measurements for Part 15.225 are made in radiated mode to comply with the field strength limits, gain information is not required to be noted in the reports or any additional documentation.
