help. The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. Device types: T50 (FCC ID: 2BU85-T50) has also been tested against this SAR limit. The highest SAR value reported under this standard during product certification for when properly worn on the body is 0.917W/kg. This device was tested fortypical body-worn operations with the back of 0mm from the body. To maintain compliance with FCC RF exposure requirements, use accessories that maintain a 0mm separation distance between the user's body . 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. Body-worn Operation This device was tested for typical body-worn operations. To comply with RF exposure requirements, a minimum separation distance of 0mm must be maintained between the user’s body and the handset, including the antenna. Third-party belt-clips, holsters, and similar accessories used by this device should not contain any metallic components.Body-worn accessories that do not meet these requirements may not comply with RFexposure requirements and should be avoided. Use only the supplied or an approved antenna. ISED Caution:
