Specific Absorption Rate 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.

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.

1. In the United States and Canada, the SAR limit for mobile phones used
by the public is 1.6 watts/kg (W/kg) averaged over one gram of tissue.
The standard incorporates a substantial margin of safety to give
additional protection for the public and to account for any variations in
measurements.

assessment procedure, and measurement uncertainty range for
this product.
