RF exposure information
FCC ID: 2AFW2B020

1. Introduction:
The EUT is designed to be used in portable exposure conditions.
This product is a Bluetooth keyboard operated in 2402~2480 MHz frequency band.

2. Output power considerations:
Worst case output power: 2. 71dBm = 1.87mW (at 2402MHz)

3. Compliance criteria:
According to 447498 D01 General RF Exposure Guidance v05 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
f(GHz) is the RF channel transmit frequency in GHz
Power and distance are rounded to the nearest mW and mm before calculation

Calculate:

(1.87/5)*√f(2.402) = 0.58 < 3 for 1g SAR

Then SAR evaluation is not required.
