RF EXPOSURE EVALUATION 1. PRODUCT INFORMATION Product Description Cash Register Model Name TPS680 FCC ID 2AJ2B-TPS680 2. EVALUATION METHOD AND LIMIT Human exposure to RF emissions from mobile devices (47 CFR §2.1091) may be evaluated based on the MPE limits adopted by the FCC for electric and magnetic field strength and/or power density, as appropriate, since exposures are assumed to occur at distances of 20 cm or more from persons. LIMITS FOR GENERAL POPULATION / UNCONTROLLED EXPOSURE Frequency Range (MHz) E-field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) (mW/cm 2 ) Averaging Time |E| 2 , |H| 2 or S (Minutes) 0.3 -- 1.34 614 1.63 (100)* 30 1.34 -- 30 824/f 2.19/f (180/f 2 )* 30 30 -- 300 27.5 0.073 0.2 30 300 -- 1500 -- -- f/1500 30 1500 -- 100,000 -- -- 1.0 30 *Note: 1. f= Frequency in MHz * Plane-wave Equivalent Power Density 2. The averaging time for General Population/Uncontrolled exposure to fixed transmitters is not applicable for mobile and portable transmitters. See 47 CFR §§2.1091 and 2.1093 on source-based time-averaging requirement for mobile and portable transmitters. S=PG/4πR² Where: S=power density P=power input to antenna G=power gain of the antenna in the direction of interest relative to an isotropic radiator R=distance to the center of radiation of the antenna CALCULATION A minimum test separation distance ≥ 20 cm is required between the antenna and radiating structures of the device and nearby persons to apply mobile device exposure limits. The distance must be at least 20 cm and fully supported by the operating and installation configurations of the transmitter and its antenna(s), according to the source-based time-averaged maximum power requirements of § 2.1091(d)(2). In cases where cable losses or other attenuations are applied to determine compliance, the most conservative operating configurations and exposure conditions must be evaluated. 2.4G WIFI Antenna Gain=0dBi (Numeric 1.00), π=3.14 BLE Antenna Gain=0dBi (Numeric 1.00), π=3.14 BR Antenna Gain=0dBi (Numeric 1.00), π=3.14 Note: 1. Only the worst case recorded. 2. The 2.4GHz WIFI band and BT band can transmit simultaneously. 0.010416266/1+0.001045231/1=0.011461497<1 3. conclusion Compliance the RF exposure requirement Frequency Output Power Output Power Power Density Power Density Limit MHz dBm mW mW/cm 2 mW/cm 2 2412 17.18 52.348 0.010416266 1 Frequency Output Power Output Power Power Density Power Density Limit MHz dBm mW mW/cm 2 mW/cm 2 2440 5.992 3.974 0.000790701 1 Frequency Output Power Output Power Power Density Power Density Limit MHz dBm mW mW/cm 2 mW/cm 2 2402 7.204 5.253 0.001045231 1
