CERPASS TECHNOLOGY CORP. Report No.: TEFI1904074-975 12. Radio Frequency Exposure 12.1 Applicable Standards The measurements shown in this test report were made in accordance with the procedures given in FCC Part 2 (Section 2.1093) KDB 447498 IEEE C95.1 LIMIT KDB 447498 D01 § 4.3(a) For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(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 extrem *f(GHz) is the RF channel transmit frequency in GHz *The values 3.0 and 7.5 are referred to as numeric thresholds in step b) below 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 according to 4.1 f) is applied to determine SAR test exclusion 12.2 EUT Specification Frequency band SRD: 2400MHz ~ 2483.5MHz (Operating) Bluetooth: 2402MHz ~ 2480MHz Portable (<20cm separation) Device category Mobile (>20cm separation) Exposure Occupational/Controlled exposure classification General Population/Uncontrolled exposure Single antenna Multiple antennas Antenna diversity Tx diversity Rx diversity Tx/Rx diversity MPE Evaluation* Evaluation applied SAR Evaluation N/A Remark: 1. The maximum conducted output power is 4.19dBm (2.624mW) at 2403.35MHz (with 1.58dBi antenna gain.) 2. DTS device is not subject to routine RF evaluation; MPE estimate is used to justify the compliance. 3. For mobile or fixed location transmitters, no SAR consideration applied. *Note: Simultaneous transmission is not applicable for this EUT. Cerpass Technology Corp.

CERPASS TECHNOLOGY CORP. Report No.: TEFI1904074-975 12.3 Test Results According to the KDB447498: The SAR test exclusion thresholds Level: [(max. power of channel, including tune-up tolerance, mW) /(min. test separation distance, mm)] * sqrt (freq. in GHz) < 3 Calculation ANT1 SAR test exclusion Channel Frequency Max. Conducted Max. Conducted Distance thresholds (MHz) output power(dBm) output power(mW) (mm) (mW) 2403.35-2477.35 4.19 2.624 5 10.00 ANT2 SAR test exclusion Channel Frequency Max. Conducted Max. Conducted Distance thresholds (MHz) output power(dBm) output power(mW) (mm) (mW) 2403.35-2477.35 3.85 2.427 5 10.00 Since the source-based time-averaging conducted output power is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing Cerpass Technology Corp.
