FCC ID : 2AKI8-CRADLE 1. RF EXPOSURE 1.1.The Requirement System operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission’s guidelines. See Section 15.247(b)(4) and Section 1.1307(b)(1) 1.2.Limit For Maximum Permissible Exposure (MPE) Limits for General Population/ Uncontrolled Exposure Power Density Averaging Time Frequency Electric Field Magnetic Field (S) 2 2 Range Strength (E) Strength (H) E ,H or S 2 (MHz) (V/m) (A/m) ( mW/cm ) (minutes) 0.3-1.34 614 1.63 (100)* 30 1.34-30 824/f 2.19/f (180/f)* 30 30-300 27.5 0.073 0.2 30 300-1500 f/1500 30 1500-100,000 1.0 30 F = frequency in MHz, * Plane-wave equivalent power density 1.3.MPE Calculation Method Predication of MPE limit at a given distance Equation from page 18 of OET Bulletin 65, Edition 97-01 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 From the peak EUT RF output power, the minimum mobile separation distance, d=0.2m, as well as the gain of the antenna is 0dBi, the RF power density can be obtained.

1.4.TEST RESULTS Maximum measured transmitter power Test Minimum Output Target Target Antenna Power Power Frequency Separation Power power power Gain Density Density Test Distance (dBm) (dBm) (mW) (Numeric) At 20 cm Limit Results （MHz） (cm) (mW/cm2) (mW/cm2) 2406 20.00 9.96 10±1 12.589 1 0.0025 1.000 Pass 2439 20.00 9.66 10±1 12.589 1 0.0025 1.000 Pass 2475 20.00 9.64 10±1 12.589 1 0.0025 1.000 Pass The measurement results comply with the FCC Limit per 47 CFR 2.1091 for the uncontrolled RF Exposure. 1.5.FCC Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, Human proximity to the antenna shall not be less than 20cm(8 inches) during normal operation. Proposed RF exposure safety information to include in User’s Manual.

IC : 22462-CRADLE 2. RF EXPOSURE 2.1.Exemption Limits for Routine Evaluation – RF Exposure Evaluation RSS-102 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: 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 ƒ0.6834 W (adjusted for tune-up tolerance), where ƒ is in MHz 2.2.TEST RESULTS Maximum measured transmitter power Channel Minimum Antenna E.I.R.P Target Max Limit Test Frequency Separation gain (dBm) power Target (W) Results (MHz) Distance (dBi) (dBm) power (cm) (W) 2406 20.00 0 9.96 10±1 0.0126 2.679 Pass 2439 20.00 0 9.66 10±1 0.0126 2.705 Pass 2475 20.00 0 9.64 10±1 0.0126 2.732 Pass The measurement results comply with the IC Limit for the uncontrolled RF Exposure. Conclusion: No SAR is required.
