SAR Data
This model wireless phone meets the
government’s requirements for exposure to radio
waves.
Your wireless phone is a radio transmitter and receiver. It is
designed and manufactured not to exceed limits for exposure to
radio frequency (RF) energy set by the Federal Communications
Commission (FCC) of the U.S. Government and by the Canadian
regulatory authorities. These limits are part of comprehensive
guidelines and establish permitted levels of RF energy for the
general population. 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.
The exposure standard for wireless mobile phones employs a unit
of measurement known as the Specific Absorption Rate, or SAR.
The SAR limit set by the FCC and by the Canadian regulatory
authorities is 1.6 W/kg.
1 Tests for SAR are conducted using
standard operating positions accepted by the FCC and by Industry
Canada with the phone transmitting at its highest certified power
level in all tested frequency bands. Although the SAR is
determined at the highest certified power level, the actual SAR
level of the phone while operating can be well below the
maximum value. This is because the phone is designed to operate
at multiple power levels so as to use only the power required to
reach the network. In general, the closer you are to a wireless
base station, the lower the power output.
Before a phone model is available for sale to the public in the U.S.
and Canada, it must be tested and certified to the FCC and Industry
Canada that it does not exceed the limit established by each
government for safe exposure. The tests are performed in
positions and locations (e.g., at the ear and worn on the body)
reported to the FCC and available for review by Industry Canada.
The highest SAR value for this model phone when tested for use at
the ear is 1.08 W/kg, and when worn on the body, as described in
this user guide, is 0.55 W/kg. The SAR value for this product in its
data transmission mode (body-worn use) is 0.31 W/kg. (Body-worn
measurements differ among phone models, depending upon
available accessories and regulatory requirements).

While there may be differences between the SAR levels of various
phones and at various positions, they all meet the governmental
requirements for safe exposure. Please note that improvements to
this product model could cause differences in the SAR value for
later products; in all cases, products are designed to be within the
guidelines.
