Output power listed is conducted. This device has 20 MHz and 40 MHz bandwidth mode and approved for use in the handset described in this filing. SAR compliance for body-worn operations is restricted to belt-clips, holsters, or similar accessories that have no metallic component in the assembly and which provide at least 1 cm separation between the device including its antenna and the body of user. End-users must be informed of the body-worn accessory operating requirements for satisfying RF exposure compliance. The highest reported SAR for head, body-worn accessory, product specific (wireless router), and simultaneous transmission exposure conditions are 0.15 W/kg, 0.17 W/kg, 0.17 W/kg, and 1.03 W/kg, respectively.

Power output listed is ERP for Part 22 and Part 27 below 1 GHz, EIRP for Part 24 and Part 27 above 1 GHz. SAR compliance for body-worn operating conditions is restricted to belt clips, holsters or similar accessories that have no metallic component in the assembly and must provide a minimum separation distance of 1 cm between the device and the body. End-users must be informed of the body-worn operating requirements for satisfying RF exposure compliance. The highest reported SAR for head, body-worn accessory, product specific (wireless router), and simultaneous transmission exposure conditions are 0.28 W/kg, 0.86 W/kg, 0.86 W/kg, and 1.03 W/kg, respectively. This device contains functions that are not operational in the U.S. Territories. This filing is only applicable for U.S. operations.
