Test Requirement: FCC Part 1.1307
Evaluation Method FCC Part2.1093 & KDB 447498 D01 General RF Exposure Guidance v06
5.1 Requirements

1) 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 S
AR where

1. f(GHz) is the RF channel transmit frequency in GHz
2. Power and distance are rounded to the nearest mW and mm before calculation
3. The result is rounded to one decimal place for comparison
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 is applied to determine SAR test exclusion.

Remark: Max. duty factor is 100%
Low Chanel: f=2402MHz=2.402GHz, so √f(GHz)=1.550
High Chanel: f=2480MHz=2.480GHz, so √f(GHz)=1.575

5.3 Result: Compliance

No SAR measurement is required.
