RF Exposure Reference: CFR 47 FCC Part 1.1310 RSS-102. Issue 5 Description: All 3 transmitters in the device have the possibility of transmitting simultaneously. The worst-case exposure for each transmitter was used to calculate the percentage of the allowable limit that each transmitter contributed. All of the percentages were then added together to verify that at the specified operating distance, they were below the allowable limit. All measurements were peak or RMS power readings taken from test reports from accredited test labs. Antenna gains were taken from the manufacturer’s specifications. Limits: Maximum exposure limits from CFR 47, FCC Part 1.1310: Table 1 - Limits for Maximum Permissible Exposure (MPE) Frequency range Electric field strength Magnetic field strength Power density Averaging time (MHz) (V/m) (A/m) (mW/cm2) (minutes) (A) Limits for Occupational/Controlled Exposure 0.3-3.0 614 1.63 *100 6 3.0-30 1842/f 4.89/f *900/f2 6 30-300 61.4 0.163 1.0 6 300-1,500 f/300 6 1,500-100,000 5 6 (B) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *100 30 1.34-30 824/f 2.19/f *180/f2 30 30-300 27.5 0.073 0.2 30 300-1,500 f/1500 30 1,500-100,000 1.0 30 Page 1 of 2
