RF Exposure Analysis
FCC ID: YRWCRONE
Analysis for FCC portable use
Standalone SAR test exclusion considerations are defined in KDB 447498 D01, Chapter 4.3.1
where the 1-g head or body and 10-g extremity SAR exclusion threshold is defined by the
following formula:
[(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
• f(GHz) is the RF channel transmit frequency in GHz
• Power and distance are rounded to the nearest mW and mm before calculation
• The result is rounded to one decimal place for comparison
For the Card Reader One the maximum conducted output power is +3.8dBm (2.4mW) at 2.4GHz
Applying the above data using the given KDB 447498 D01 formula, and minimum separation
distance of 5mm, the following results:
(2.4mW / 5 mm) x √2.4 GHz = 0.74
(i.e. ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR)

Conclusion
This demonstrates the Card Reader One meets the criteria for 1-g head body and 10-g
extremity SAR test exemption.

Yours faithfully,

Stefan Mitov
