FCC RF Exposure

EUT Description: SK631
Model No.: SK-631-GKLR1-US
FCC ID: 2AR8X-SK631

1. Limits
According to KDB 447498 D01 General RF Exposure Guidance v06 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:
Result=P/D*√F
F= the RF channel transmit frequency in GHz
P=Maximum turn‐up power in mw
D=Min. test separation distance in mm

Conducted power see the test report HK1812242035‐E, antenna gain=0dBi

Per KDB 447498 D01, when the minimum test separation distance is < 5 mm, a distance of 5 mm is
applied to determine SAR test exclusion. The test exclusion threshold is 0.315 which is<= 3, SAR
testing is not required.

Note: Exclusion Thresholds Results=[(max. power of channel, including tune-up tolerance, mW)/(min. test
separation distance, mm)] ·[√f(GHz)]
f(GHz) is the RF channel transmit frequency in GHz
