SAR Information
The device meets guidelines for exposure to radio waves.
Your device is a radio transmitter and receiver. It is designed not to exceed
the limits for exposure to radio waves recommended by international
guidelines. These guidelines were developed by the independent scientific
organization ICNIRP and include safety margins designed to assure the
protection of all persons, regardless of age and health.
The exposure guidelines for mobile devices employ a unit of measurement
known as the Specific Absorption Rate or SAR. The SAR limit stated in the
ICNIRP guidelines is 2.0 W/kg averaged over 10 grams of tissue. Tests for
SAR are conducted using standard operating positions with the device
transmitting at its highest certified power level in all tested frequency bands.
The actual SAR level of an operating device can be below the maximum
value because the device is designed to use only the power required to reach
the network. That amount changes depending on a number of factors such as
how close you are to a network base station. The highest SAR value under
the ICNIRP guidelines for use of the device at the body is 0. W/kg. Use of
device accessories and enhancements may result in different SAR values.
SAR values may vary depending on national reporting and testing
requirements and the network band. The device could be used with a
separation distance of ??? cm to the human body.
FCC Regulations:
