Specific Absorption Rate (SAR) information: This BlueCash-50 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: Smartphone has also been tested against this SAR
limit. This device was tested for typical body-worn operations with the back of the BlueCash-50
kept 0mm from the body. To maintain compliance with FCC RF exposure requirements, use
accessories that maintain an 0mm separation distance between the user's body and the back of the
phone. The use of
