Specific Absorption Rate (SAR)
Specific Absorption Rate (SAR)
SoftBank 009SH meets 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/kg*. 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 of SoftBank 009SH is 0.551 W/kg. SAR
tests were conducted with handset transmitting at its highest
certified power level in accordance with 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
following Websites.
