FCC SAR Test Lab: CA3874 Celltech Labs Inc. 21-364 Lougheed Road Kelowna, BC, Canada V1X7R8 To: Federal Communications Commission 7435 Oakland Mills Road Columbia, Maryland 21046 USA RE: Garmin International Inc. FCC ID: IPH-04743 This is an application for a new certification of Garmin International Inc., FCC ID: IPH-04743, Model: A04743. The A04743 is a portable headset consisting of a Bluetooth/Bluetooth LE transceiver operating between 2402 and 2480MHz. In accordance with 47 CFR §2.1093, an RF Exposure evaluation is required for this device. Below is the analysis of that evaluation. The maximum antenna port conducted power of the transmitter (including tune-up tolerance) is 6.3mW (8.0dBm) with an antenna gain of 3.0dBi. The maximum EIRP is given by: EIRP = P + G = 8.0dBm + 3.0dBi = 11.0dBm = 12.6mW. A minimum separation distance exists between the radiating element and the user of 2.0cm (20mm), and cannot be altered by the user. As per FCC KDB 447498 D01v06, Annex A, the SAR Test Exclusion Threshold at 2450MHz with a 20mm separation distance is: 38mW. This device is exempt from routine SAR evaluation. Should there be any questions or concerns with this filing, please feel free to contact me. Art Voss, P.Eng. Technical Manager Celltech Labs Inc. 12 March 2024 Date I attest that the data reported herein is true and accurate. This report has been completed in accordance with ISO/IEC 17025.

Summary The equipment or product described in section 5 of this report was tested at the Garmin Compliance Lab according to standards listed in section 6. This report focuses on the 2.4 GHz Bluetooth transceiver under the FHSS rules. The product also includes 2.4 GHz BLE radio that are being certified under the DTS rules. To aid the reader, we have moved the reporting of DTS compliance into a separate report, GCL Test Report 2024-036. Some of the test records in this report may also provide data for those DTS radios. Please ignore any data for BLE radio that appear within the test records. The results are as follows. Parameter Description Key Performance Values Result Data starts at page Radio Modulation Summary of the kinds of communication this radio can achieve, as stated by the client. [RSS-GEN at Annex A item 10b] Digitally modulated frequency hopping spread spectrum at rates as high as 3 Mbps. Reported N/A Hopping Channels The radio manages it use of channels appropriately. [15.247(a)(1); RSS-247 at 5.1] The system uses 79 hopping channels separated by at least 2/3 of the 20 dB Bandwidth. Channels are used on an appropriately equal time basis. PASS 12 DTS Bandwidth The nature of the radio signal is broadband, being at least 500 kHz wide. [15.247(a)(2); RSS-247 at 5.2(a)] Only relevant for DTS systems. N/A N/A Other Bandwidths Regulatory agencies also require the reporting of signal bandwidths using alternate processes. [2.202; RSS-GEN at 6.7] These values are reported but have no actual performance requirements. Reported 16 Transmit Power The peak transmit power presented to the antenna is no greater than 1 Watt or 30 dBm. The effective radiated power is limited to 4 Watts or 36 dBm EIRP. [15.247(b); RSS-247 at 5.4(d)] The maximum transmit power is 4.64 dBm or 1.66 mW. PASS 21 Antenna Gain The radio should not focus too much energy in any direction. Unless additional rules are applied, the antenna gain is no greater than 6 dBi. [15.247(b)(4) and (c)] NT. The client stated that the antenna gain was 3 dBi and will document antenna gain separately. NT NT Unwanted Emissions (Conducted Spurious) The radio should not provide too much radio energy to the antenna at frequencies beyond its intended frequency band. [15.247(d); RSS-247 at 5.5] Emissions outside the band must be reduced at least 20 dB from in-band levels. The measured reduction was at least 53.23 dB. PASS 23 Page 3 of 47 GCL Test Report 2024-037 Version A This report may be reproduced in whole. Reproduction of parts or excerpts requires lab management approval. Garmin Restricted Bands The radio must not emit in certain designated restricted frequency bands above a set of limit values. [15.247(d) and 15.205; RSS- 247 at 3.3] Emissions in the restricted bands were at least 16.98 dB below the applicable limits. PASS 26 Power Spectral Density The radio must not focus too much radio energy in a narrow frequency band. [15.247(e); RSS-247 at 5.2(b)] Not relevant to FHSS systems. N/A N/A Hybrid Systems A radio that is both frequency hopping and digitally modulated should satisfy a combination of system rules. [15.247(f); RSS-247 at 5.3] N/A. The radios described in this report are not subjected to the Hybrid System rules. N/A N/A Frequency Hopping Rules Frequency hopping systems have additional functional requirements. [15.247(g) and (h); RSS-247 at 5.1] These functional requirements are design parameters, but not testable requirements. NT NT Radio Safety The radio emissions must meet public health & safety guidelines related to human exposure. [15.247(i) and 1.1307; RSS- Gen at 3.4] NT. Client will report radio energy safety results separately. NT NT Frequency Stability The radio tuning must be robust over a range of temperature and supply voltage conditions. [RSS-Gen at 6.11] Radio emissions remained within the allowed radio band under all environmental conditions tested. PASS 30 Unwanted Emissions (Radiated Spurious) While transmitting, the radiated emissions must not be too strong. [15.209, RSS- Gen at 8.9] Emissions other than the fundamental and harmonics must meet the ‘Class B’ limits. The measured emissions had at least 9.6 dB of margin. PASS 34 Unwanted Emissions (Mains Conducted) While transmitting, the emissions conducted into the power mains must not be too strong. [15.207, RSS-Gen at 8.8] Emissions other than the fundamental and harmonics must meet the ‘Class B’ limits. The measured emissions had at least 13.46 dB of margin. PASS 44 NT (Not Tested) means the requirement may or may not be applicable, but the relevant measurement or test was not performed as part of this test project. N/A (Not Applicable) means the lab judged that the test sample is exempt from the requirement.
