Specific Absorption Rate (SAR)
812SH and 813SH meet the government's requirements
for exposure to radio waves.
These requirements are based on scientific basis to assure
that radio waves emitted from mobile phones and other
handheld wireless devices do not affect human health. They
require that the Specific Absorption Rate (SAR), which is
the unit of measurement for the amount of radiofrequency
absorbed by the body, shall not exceed 2 W/k
This limit includes a substantial safety margin designed to
assure the safety of all persons, regardless of age or health,
and meets the international standard set by International
Commission on Non-Ionizing Radiation Protection (ICNIRP)
in cooperation with World Health Organization (WHO).
The highest SAR value is 1.43 W/k for 812SH, and 1.50 W/k
for 813SH. Tests for SAR are conducted with handset
transmitting at its highest certified power level, and follow the
testing methods set by the government. While there may be
differences between the SAR levels for various handsets, they
all meet the governmental requirements for safe exposure.
The actual SAR level of the handset while operating can be
well below the highest value. This is because the handset is
designed to operate at multiple power levels so as to use only
the power required to reach the Network.
Additional information on SAR can be obtained on the
Websites on the right.
