RF Exposure Evaluation Reference: CFR 47 FCC Part 1.1310 RSS-102. Issue 5 Description: All 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 4

YES Table 2 - Calculations according to CFR 47, Part 1.1310, Table 1(B) When measurements were performed as EIRP, the antenna gain is listed as 1. In cases where the antenna gain is not listed as 1, the power measurement was performed as conducted and the antenna gain from the manufacturer’s datasheet was used. The power density is calculated as shown below: S = (P x G)/(4 x π x d^2) – used to calculate exposure at 20 cm d = √(S/(P x G) x 4 X π) – used to calculate minimum distance to meet limits 1 mW/cm^2 = 10 W/m^2 Page 2 of 4

RF Exposure Evaluation Using RSS-102, Issue 5, Section 2.5.2 RF exposure evaluation is required if the separation distance between the user and/or bystander and the device’s radiating element is greater than 20 cm, except when the device operates as follows: • below 20 MHz6 and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 1 W (adjusted for tune-up tolerance); • at or above 20 MHz and below 48 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 4.49/ƒ0.5 W (adjusted for tune-up tolerance), where ƒ is in MHz; • at or above 48 MHz and below 300 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 0.6 W (adjusted for tune-up tolerance); • at or above 300 MHz and below 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 1.31 x 10-2 ƒ^(0.6834) W (adjusted for tune-up tolerance), where ƒ is in MHz; • at or above 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 5 W (adjusted for tune-up tolerance). In these cases, the information contained in the RF exposure Page 3 of 4
