Test Report No.: HP190708DC001-FMP 1. RF exposure limit Limits for maximum permissible exposure (MPE) Limits for general population / uncontrolled exposure Frequency range Electric field strength Magnetic field strength Power density Average time 2 (MHz) (V/m) (A/m) (mW/cm ) (minutes) 300-1500 … … F/1500 30 1500-100,000 … … 1.0 30 Note: F = Frequency in MHz 2. MPE calculation formula Pd = (Pout*G) / (4*pi*r2) Where: 2 Pd = power density in mW/cm Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm Classification: The antenna of this product, under normal use condition, is at least 20cm away from the body of the user.
