RF Exposure Information
The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. Device types
HG-M320 (FCC ID: SG71001HG-M320) has also been tested against this SAR limit. The
highest SAR value reported under this standard during product certification for use at the
ear is 1.271 W/kg and when properly worn on the body is 1.282 W/kg. This device was
tested for typical body-worn operations with the back of the handset kept 1.5cm from the

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.
