SAR Information
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 (FCC) 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 the safety standards that were developed by independent scientific organizations
through periodic evaluation of 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 phones employs a unit of measurement known
as Specific Absorption Rate (SAR). The SAR limit set by the FCC is 1.6 W/kg.
The highest SAR values for this model phone were Head: 0.682 W/kg, and
Body: 0.772 W/kg.
