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

avoided.
