THIS MODEL PHONE MEETS THE GOVERNMENT’S REQUIREMENTS FOR EXPOSURE TO RADIO WAVES.

Your wireless phone is a radio trans- mitter and receiver. It is designed and manufactured not to exceed the emis- sion limits for exposure to radiofre- quency (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 ener- gy for the general population. The guidelines are based on standards that were developed by independent scientific organizations through peri- odic and thorough evaluation of scien- tific studies. The standards include a substantial safety margin designed to assure the safety of all persons, re- gardless 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 conducted using standard operating positions accepted by the FCC with the phone transmit- ting at its highest certified power level

in all tested frequency bands. Al- though 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 multi- ple 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 of the mobile phone.

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 per- formed in positions and locations (e.g., at the ear and worn on the body) to determine SAR compliance for the particular device at a range of potential operating positions. The highest SAR value for this model phone when tested for use at the ear is 0.33 W/kg and when worn on the body in accordance with instructions in this user guide is 1.54 W/kg. (Body- worn measurements differ among phone models, depending upon avail-

able accessories). While there may be differences between the SAR levels of various phones and at various posi- tions, they all meet the government requirement for RF 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 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 NRR-S4X.

Additional information on Specific Absorption Rates (SAR) can be found on the Cellular Telecommunications Industry Association (CTIA) web-site at http://www.wow-com.com.

NOTE:

*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 sub- stantial margin of safety to give additional protection for the public and to account for any variations in measurements.
