Specific Absorption Rate (SAR)
831P 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
head, 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 for 831P is 0.504 W/kg. 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.
