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 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.
The highest SAR value for this model phone when tested for use at the ear is 0.47 W/kg and when worn on the body, as
described in this user's manual, is 0.56 W/kg. While there may be differences between SAR levels of various phones and at
various positions, they all meet the government requirement for safe exposure.
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 ZNFB460.
To find information that pertains to a particular model phone, this site uses the phone FCC ID number which is usually printed
somewhere on the case of the phone. Sometimes it may be necessary to remove the battery pack to find the number. Once
you have the FCC ID number for a particular phone, follow the instructions on the website and it should provide values for
typical or maximum SAR for a particular phone.
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.
HAC
This phone has been tested and rated for use with hearing aids for some of the wireless technologies that it uses. However,
there may be some newer wireless technologies used in this phone that have not been tested yet for use with hearing aids.
It is important to try the different features of this phone thoroughly and in different locations, using your hearing aid or
cochlear implant, to determine if you hear any interfering noise. Consult your service provider or the manufacturer of this
phone for information on hearing aid compatibility. If you have questions about return or exchange policies, consult your
service provider or phone retailer.
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.
The wireless telephone industry has developed a rating system for wireless phones, to assist hearing device users to find
phones that may be compatible with their hearing devices. Not all phones have been rated. Phones that are rated have the
rating on their box or a label located on the box.
The ratings are not guarantees. Results will vary depending on the user's hearing device and hearing loss. If your hearing
device happens to be vulnerable to interference, you may not be able to use a rated phone successfully. Trying out the phone
with your hearing device is the best way to evaluate it for your personal needs.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to generate less interference to hearing devices
than phones that are not labeled. M4 is the better/ higher of the two ratings.
T-Ratings: Phones rated T3 or T4 meet FCC requirements and are likely to generate less interference to hearing devices than
phones that are not labeled. T4 is the better/ higher of the two ratings.
Hearing devices may also be rated. Your hearing device manufacturer or hearing health professional may help you find this
rating. Higher ratings mean that the hearing device is relatively immune to interference noise.
The hearing aid and wireless phone rating values are then added together. A sum of 5 is considered acceptable for normal
use. A sum of 6 is considered for best use.
In the example to the left, if a hearing aid meets the M2 level rating and the wireless phone meets the M3 level
rating, the sum of the two values equal M5.
This should provide the hearing aid user with "normal usage" while using their hearing aid with the particular wireless phone.
"Normal usage" in this context is defined as a signal quality that's acceptable for normal operation.
The M mark is intended to be synonymous with the U mark. The T mark is intended to be synonymous with the UT mark. The
M and T marks are recommended by the Alliance for Telecommunications Industries Solutions (ATIS). The U and UT marks
are referenced in Section 20.19 of the FCC Rules. The HAC rating and measurement procedure are described in the American
National Standards Institute (ANSI) C63.19 standard.
When you're talking on a cell phone, it's recommended that you turn the BT (Bluetooth) mode off for HAC.
