What is a SAR value?
Every mobile device model is tested for radio wave emissions. Using an internationally standardized method that meets government and regulatory requirements, a measurement is made to determine how much electromagnetic energy is absorbed by body tissue. This gives the SAR (specific absorption rate) value. Governmental and regulatory agencies have established SAR limits under which mobile device use has been determined by them to be safe. All Microsoft devices are designed to comply with the relevant governmental SAR level.
