upon available accessories and FCC requirements). While there may be differences between
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 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/fccid after searching on FCC ID ZNFV495. 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 device 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.
Caution: Avoid potential hearing loss.
Prolonged exposure to loud sounds (including music) is the most common cause of
preventable hearing loss. Some scientific research suggests that using portable audio
devices, such as portable music players and cellular telephones, at high volume settings
for long durations may lead to permanent noise-induced hearing loss. This includes the use
of headphones (including headsets, earbuds and Bluetooth® or other wireless devices).
Exposure to very loud sound has also been associated in some studies with tinnitus (a
ringing in the ear), hypersensitivity to sound and distorted hearing. Individual susceptibility
to noise-induced hearing loss and other potential hearing problems varies. The amount of
sound produced by a portable audio device varies depending on the nature of the sound,
the device, the device settings and the headphones. You should follow some commonsense
recommendations when using any portable audio device:
