1. CERTIFICATION PRODUCT: WeMo Door & Window Sensor BRAND NAME: Belkin MODEL NO.: F7CO38 TEST SAMPLE: ENGINEERING SAMPLE APPLICANT: Belkin, International Inc., TESTED: Nov. 03, 2014 STANDARDS: FCC Part 2 (Section 2.1091) KDB 447498 DO3 IEEE C95.1 The above equipment (Model: F7CO38) has been tested by Bureau Veritas Consumer Products Services (H.K.) Ltd., Taoyuan Branch, and found compliance with the requirement of the above standards. The test record, data evaluation & Equipment Under Test (EUT) configurations represented herein are true and accurate accounts of the measurements of the sample‘s EMC characteristics under the conditions specified in this report.

2. RF EXPOSURE LIMIT LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) FREQUENCY ELECTRIC FIELD MAGNETIC FIELD POWER DENSITY AVERAGE TIME RANGE (MHz) STRENGTH (V/m) STRENGTH (A/m) (mW/cm2) (minutes) LIMITS FOR GENERAL POPULATION / UNCONTROLLED EXPOSURE 300-1500 … … F/1500 30 1500-100,000 … … 1.0 30 F = Frequency in MHz 3. MPE CALCULATION FORMULA Pd = (Pout*G) / (4*pi*r2) where Pd = power density in mW/cm2 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 4. CLASSIFICATION The antenna of this product, under normal use condition, is at least 20cm away from the body of the user. So, this device is classified as Mobile Device. 5. ANTENNA GAIN The antenna provided to the EUT, please refer to the following table: Antenna Frequency Brand Antenna Type Gain(dBi) Connector range (GHz) NA PIFA NA 2.22 2.4~2.4835 Report No.: SA141008E01 5 of 6 Report Format Version 5.0.1

6. CALCULATION RESULT OF MAXIMUM CONDUCTED POWER For Zigbee FREQUENCY CONDUCTED ANTENNA POWER DISTANCE LIMIT BAND POWER GAIN DENSITY (cm) (mW/cm2) (MHz) (mW) (dBi) (mW/cm2) 2405 - 2475 6.095 2.22 20 0.00202 1.00 --- END --- CONCLUSION: Both of the WLAN and Zigbee can transmit simultaneously, the formula of calculated the MPE is: CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1 CPD = Calculation power density LPD = Limit of power density Therefore, the worst-case situation is 0.10417 / 1 + 0.00367 / 1= 0.108, which is less than “1”. This confirmed that the device comply with FCC 1.1310 MPE limit. Report No.: SA141008E01 6 of 6 Report Format Version 5.0.1
