Safety
(Body-worn 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/ea/fccid after searching on FCC ID ZNFVS425.
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 margin of safety to give additional
protection for the public and to account for any variations in
measurements.
FCC Hearing-Aid Compatibility (HAC) Regulations
for Wireless Devices
On July 10, 2003, the U.S. Federal Communications Commission (FCC)
Report and Order in WT Docket 01-309 modified the exception of wireless
phones under the Hearing Aid Compatibility Act of 1988 (HAC Act) to
require digital wireless phones be compatible with hearing-aids. The intent
of the HAC Act is to ensure reasonable access to telecommunications
services for persons with hearing disabilities.
While some wireless phones are used near some hearing devices (hearing
aids and cochlear implants), users may detect a buzzing, humming, or
whining noise. Some hearing devices are more immune than others to this
interference noise, and phones also vary in the amount of interference they
generate.
