standard in a regulation. In August 1996, the FCC adopted hybrid standard consisting of the existing
ANSI/IEEE standard and the guidelines published by the National Council of Radiation Protection and
Measurements (NCRP).
Body-Worn Operation
This device was tested for typical body-worn operations with the back of the phone kept 0.39 inches
(1cm) between the user's body and the back of the phone. To comply with FCC RF exposure
requirements, a minimum separation distance of 0.39 inches (1cm) must be maintained between the
user's body and the back of the phone. Third-party belt-clips, holsters, and similar accessories containing
metallic components may not be used. Body-worn accessories that cannot maintain 0.39 inches (1cm)
separation distance between the user's body and the back of the phone, and have not been tested for
typical body-worn operations may not comply with FCC RF exposure limits and should be avoided.

SAR (Specific Absorption Rate)
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 radiofrequency (RF) energy set by the Federal Communications Commission (FCC)
of the U.S. Government. These FCC exposure limits are derived from the recommendations of two expert
organizations, the National Counsel on Radiation Protection and Measurement (NCRP) and the Institute
of Electrical and Electronics Engineers (IEEE). In both cases, the recommendations were developed by
scientific and engineering experts drawn from industry, government, and academia after extensive
reviews of the scientific literature related to the biological effects of RF energy.
The exposure limit for wireless mobile phones employs a unit of measurement known as the Specific
Absorption Rate, or SAR. The SAR is a measure of the rate of absorption of RF energy by the human
body expressed in units of watts per kilogram (W/kg). The FCC requires wireless phones to comply with a
safety limit of 1.6 watts per kilogram (1.6 W/kg). The FCC exposure limit incorporates a substantial
margin of safety to give additional protection to the public and to account for any variations in
measurements. 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: 1.19 W/kg
●
Body (Body-worn/Hotspot): 0.93 W/kg
