Certification Information
*Specific Absorption Rate (SAR) for wireless phone:
THIS MODEL 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 the emission limits for exposure to radio frequency (RF) energy set by the
Federal Communications Commission of the U.S Government. 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 studies. The standards include a substantial safety margin designed to assure the
safety of all persons, regardless of age and 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 is 1.6W/kg. *Tests
for SAR are conducted using standard operating positions accepted by the FCC 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 wireless base station antenna, the lower the
power output.
Before a phone model is available for sale to the public in the public, it must be tested and
certified to the FCC that it does not exceed the limit established by the government-adopted
requirement for safe exposure. The tests are performed in positions and locations (for
example, at the ear and worn on the body) as required by the FCC for each model.
