Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 3 RF Exposure Information: The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. Device Types Mobile Phone (FCC ID: 2ADYY-T420) has also been tested against this SAR limit. The highest SAR value reported under this standard during product certification for use when properly worn on the body is 1.163W/kg and head is 0.903W/kg. This device was tested for typical body worn operations with the back of the handset kept 5mm from the body. To maintain complian ce with FCC RF exposure requirements, use accessories that maintain a 5mm separation distance between the user's body and the back of the handset. The use of belt clips, holsters and similar accessories should not contain metallic components in its assembly. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements, and should be avoided. 4 Thank you for choosing this mobile phone.
