Sierra Wireless accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or receive such data. Safety and Hazards Do not operate the Sierra Wireless modem in areas where blasting is in progress, where explosive atmospheres may be present, near medical equipment, near life support equipment, or any equipment which may be susceptible to any form of radio interference. In such areas, the Sierra Wireless modem MUST BE POWERED OFF. The Sierra Wireless modem can transmit signals that could interfere with this equipment. Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED OFF. When operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard systems. Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is open. Sierra Wireless modems may be used at this time. The driver or operator of any vehicle should not operate the Sierra Wireless modem while in control of a vehicle. Doing so will detract from the driver or operator's control and operation of that vehicle. In some states and provinces, operating such communications devices while in control of a vehicle is an offence.

Standalone Power Density Calculation Band Frequency (MHz) Antenna Gain (dBi) Maximum Power (dBm) Maximum EIRP (dBm) Maximum EIRP (W) Average EIRP (mW) Power Density at 20cm (mW/cm^2) Limit (mW/cm^2) Power Density / Limit 2.4GHz WLAN 2400.0 1.43 18.00 19.430 0.088 87.700 0.017 1.000 0.017 Bluetooth 2400.0 1.43 8.00 9.430 0.009 8.770 0.002 1.000 0.002 4.2. Collocated Power Density Calculation WLAN Power Density / Limit Bluetooth Power Density / Limit Σ(Power Density / Limit) of WLAN+Bluetooth 0.017 0.002 0.019 Note: 1. Σ(Power Density / Limit): This is a summation of [(power density for each transmitter/antenna included in the simultaneous transmission)/ (corresponding MPE limit)], for WLAN + Bluetooth. 2. Considering the WLAN module collocation with the Bluetooth transmitter of the EIRP performance listed in the table above, the aggregated (power density /limit) is smaller than 1, and MPE of 2 collocated transmitters is compliant Conclusion: According to 47 CFR §2.1091, the RF exposure analysis concludes that the RF Exposure is FCC compliant.
