The use of accessories that do not satisfy
these requirements may not comply with FCC RF
exposure requirements, and should be avoided.

SAR INFORMATION
This Model Phone meets the Government’s
Requirements for Exposure to Radio Waves.
Your wireless phone 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 comprehen-
sive 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 peri-
odic 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 phones
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 con-
ducted with the phone 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
phone while operating can be well below the max-
imum value. This is because the phone 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 sta-
tion 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 highest
SAR value for this model phone when tested for
use at the ear is
1.37
W/Kg and when worn on the
body, as described in this user guide, is
0.422
W/Kg.
(Body-worn measurements differ among phone
models, depending upon available accessories and
FCC requirements). While there may be differences
between the SAR levels of various phones and at
various positions, they all meet the government
requirement for safe exposure.
The SAR testing for Body-worn operation was
performed with a belt clip that provided a 22mm
separation. The User’s Manual indicates that any
holsters/clips used with this device should contain
no metallic components.
The FCC has granted an Equipment Authorization
for this model phone with all reported SAR levels
evaluated as in compliance with the FCC RF expo-
sure 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.

Rates (SAR) can be found on the Cellular

* 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 safe-
ty 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 telecom-
munications 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 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 hear-
ing loss. If your hearing device hap-pens 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.
Hearing devices may also be rated. Your hearing
device manufacturer or hearing health profes-
sional 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 consid-
ered for best use.
In the above example, 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
