Date of Issue: Mar. 11, 2021 Report No.: WH-FCC-R21012903 Page 1/2 Radio Frequency Exposure EUT INFORMATION FCC ID FC900RBT EUT Bluetooth Keyboard Frequency band (Operating) 2402 MHz ~ 2480 MHz Max. output power -6.409 dBm Antenna gain (Max) 2.78 dBi TEST RESULT According to KDB 447498 section 4.3.1, the 1-g SAR test exclusion thresholds at test separation distance ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance,mm)] *[√f(GHz)] ≤ 3.0 Modulation Standard Frequency (MHz) Output Power (dBm) Output Power with tune-up tolerance (dBm) GFSK (1Mbps) 2402 -6.409 -6±2 2441 -6.567 -7±2 2480 -7.148 -7±2 π/4-DQPSK (2Mbps) 2402 -6.521 -6±2 2441 -6.995 -7±2 2480 -7.591 -7±2 8DPSK (3Mbps) 2402 -6.706 -6±2 2441 -7.003 -7±2 2480 -7.598 -7±2 Frequency (MHz) Output Power with tune-up tolerance (dBm) Tune up Power (mW) 2402 -4 0.398 WH Technology Corp. Date of Issue: Mar. 11, 2021 Report No.: WH-FCC-R21012903 Page 2/2 The max. average power of channel, including tune-up tolerance(mW) is 0.398 mW @ 2402 MHz (With tune-up tolerance), The min. test separation distance (mm) is 5 mm, So, [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] *[√f(GHz)] = 0.398/5*√2.402 = 0.123 < 3.0 (With Tune-up tolerance). Therefore, standalone SAR measurements are not required for both head and body.
