For Your Safety

What does “SAR” mean?

In 1996, the FCC, working with the FDA, the U.S. Environmental Protection Agency, and

other agencies, established RF exposure safety guidelines for wireless devices in the

United States. Before a wireless device model is available for sale to the public, it must

be tested by the manufacturer and certified to the FCC that it does not exceed limits

established by the FCC. One of these limits is expressed as a Specific Absorption Rate,

or “SAR”. SAR is a measure of the rate of absorption of RF energy in the body. Tests for

SAR are conducted with the device transmitting at its highest power level in all tested

frequency bands. Since 1996, the FCC has required that the SAR of handheld wireless

device not exceed 1.6 watts per kilogram, averaged over one gram of tissue.

Although the SAR is determined at the highest power level, the actual SAR value

of a wireless device while operating can be less than the reported SAR value. This

is because the SAR value may vary from call to call, depending on factors such as

proximity to a cell site, the proximity of the device to the body while in use, and the

use of hands-free devices. 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 FCC has granted an Equipment Authorization for this model device with all reported

SAR levels evaluated as in compliance with the FCC RF emission 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/ea/fccid/ after searching on FCC ID

ZNFV410.

For more information about SARs, see the FCC’s OET Bulletins 56 and 65 at http://
