RF Exposure Exhibit

Fitbit, Inc. Model FB402
FCC ID: XRAFB402

The output power of this device is 1.4 mW is low enough to satisfy the equation for SAR
exclusion in section 4.3.1 of FCC KDB 447498 at a separation distance of 0 as shown below.
(When the minimum separation distance is less than 5mm, 5mm is used in the calculation.)

(max. power, including tune-up tolerance, mW)/(min. separation distance, mm)] * [√f(GHz)] ≤ 3.0

Substituting the values in the above equation yields the following:
(1.4/5) * √2.48 = 0.44
which is less than 3
