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 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 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 1.6 W/kg. Tests for SAR are
conducted using standard operating positions specified by the FCC with the phone transmitting at
its highest certified power level in all tested frequency bands. Although 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. Because the phone is designed to operate at multiple power levels to use only
the power required to reach the network, in general, the closer you are to a wireless base station
antenna, the lower the power output.
Before a phone model is available for sale to 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 (e.g., at the ear and worn on the body)
as required by the FCC for each model.
The highest SAR values are:
• Head: 0.97 W/kg
• Body (Body-worn/Hotspot): 1.03 W/kg
(Body measurements differ among phone models, depending upon available accessories and FCC
requirements).
While there may be differences between SAR levels of various phones and at various positions, they
all meet the government requirement for safe exposure.
The FCC has granted an Equipment Authorization for this model phone with all reported SAR levels
evaluated as in compliance with the FCC RF emission guidelines. SAR information on this model
phone is on file with the FCC and can be found under the Display Grant section of http://www.fcc.
gov/oet/fccid after searching on FCC ID ZNFK330. Additional information on Specific Absorption
Rates (SAR) can be found on the Cellular Telecommunications Industry Association (CTIA) website
at http://www.ctia.org/.
* 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
