FCC RF Exposure

FCC ID: 2A86H-DF588

1. Limits

According to KDB 447498 D04 General RF Exposure Guidance v01 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 HK2209224252-E, antenna gain=-0.58dBi

Per KDB 447498 D04, 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 0.9802 which

is<= 3, SAR testing is not required.

Note: Exclusion Thresholds Results=[(max. power of channel, including tune-up tolerance,

f(GHz) is the RF channel transmit frequency in GHz
