Radio frequency (RF) signals
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 radio
frequency (RF) energy set by the Federal Communications Commission of
the U.S. Government. These limits are part of comprehensive 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 periodic 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 1.6W/kg.* Tests for SAR are conducted using
standard operating positions accepted by the FCC 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 maximum 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 station antenna,
the lower the power output.

Reference information
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 as reported to the FCC when tested for use at the ear is
1.14 W/Kg and when worn on the body, as described in this users guide,
is 1.02 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.
The FCC has granted an Equipment Authorization for this model phone
with all reported SAR levels evaluated as in compliance with the FCC RF
exposure 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/fccid after searching on FCC ID GMLNSW-4DX.
For body worn operation, to maintain compliance with FCC RF exposure
guidelines, use only Nokia approved accessories. When carrying the phone
while it is on, attach the phone to the specific belt-clip or place the phone
in the specific Nokia carrying cases that have been tested for compliance.
Use of non-Nokia-approved accessories may violate FCC RF exposure
guidelines and should be avoided.
* 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.
SAR values may vary depending on national reporting requirements and the
network band. For SAR information in other regions please look under product
information at http://www.nokia.com.
