RF Exposure evaluation
Product: MARINE AUDIO SYSTEM
Model Number: MA400
FCC ID: OPDMA400

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
The result is rounded to one decimal place for comparison

Worse case is as below: [2402MHz -5.853dBm(0.2598mW) output power]

(0.2598mW /5mm)·[√2.402(GHz)]=0.080538<3.0 for 1-g SAR

Then SAR evaluation is not required
