Specific Absorption Rate (SAR) information:
This 4G LTE PHONE meets the government's requirements for exposure to radio
waves. The guidelines are based on standards that were developed by independent
scientific organizations through periodic and thorough evaluation of scientific studies.
The standards include a substantial safety margin designed to assure the safety of all
persons regardless of age or health.
FCC RF Exposure Information and Statement
The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue.
Device types: 4G LTE PHONE (FCC ID: YPVITALCOMHIT) 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 0.323W/kg and when properly worn on the
body is 1.220W/kg. the Hotspot SAR value is 1.220W/kg,the simultaneous
transmission SAR value is 0.452W/kg on the head and 1.369W/ kg on the body. This
device was tested for typical body-worn operations with the back of the handset kept
10mm from the body. To maintain compliance with FCC RF exposure requirements,
use accessories that maintain a 10mm 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.
