Specific Absorption Rate (SAR) information:

This 4G LTE 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: Smart

phone (FCC ID: YPVITALCOMPIN) 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 1.004W/kg and when properly

worn on the body is 1.446W/kg. the Hotspot SAR value is 1.446W/kg,the simultaneous transmission SAR

value is 1.190W/kg on the head and 1.529W/ 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.

Body-worn Operation

This device was tested for typical body-worn operations. To comply with RF exposure requirements, a

minimum separation distance of 10mm must be maintained between the user’s body and the handset,
