Specific Absorption Rate (SAR) information:
This WPP-250 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: WPP-250 has also been tested against this SAR
limit. This device was tested for typical body-worn operations with the back of the WPP-250 kept 10mm from the
body. To maintain compliance with FCC RF exposure requirements, use accessories that maintain an 10mm
separation distance between the user's body and the back of the WPP-250. The use of belt clips, holsters and
similar accessories should not contain metallic components in its assembly. The use of accessories that do not
