Your wireless device 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 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
devices 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 with the
device 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 device while operating can be well below the maximum value. This is
because the device 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 a wireless
base station antenna, the lower the power output.
Before a device 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 value for this model device when worn on the body, as described in this
user guide, is 0.347W/Kg (Body-worn measurements differ among device models,
depending upon available accessories and FCC requirements). While there may be
differences between the SAR levels of various devices and at various positions, they
all meet the government requirement for safe exposure. The FCC has granted an
Equipment Authorization for this model device with all reported SAR levels evaluated
as in compliance with the FCC RF exposure guidelines.
SAR information on this model device 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:
2ADINN5501LAT
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 devices used by the public
is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The standard incorporates
a substantial margin of safety to give additional protection for the public and to
account for any variations in measurements.
Body-wornOperation
This device was tested for typical body-worn operations. To comply with RF exposure
requirements, a minimum separation distance of 5mm must be maintained between
the user’s body and the handset, including the antenna. Third-party belt-clips,
holsters and similar accessories used by this device should not contain any metallic
components. Body-worn accessories that do not meet these requirements may not
comply with RF exposure requirements and should be avoided. Use only the supplied
or an approved antenna.
