230 Section 4A: Important Safety InformationRadio Frequency (RF) EnergyUnderstanding How Your Phone OperatesYour phone is basically a radio transmitter and receiver. When it’s turnedon, it receives and transmits radio frequency (RF) signals. When you useyour phone, the system handling your call controls the power level. Thispower can range from 0.006 watts to 0.2 watts in digital mode.Knowing Radio Frequency SafetyThe design of your phone complies with updated NCRP standardsdescribed below.In 1991-92, the Institute of Electrical and Electronics Engineers (IEEE) andthe American National Standards Institute (ANSI) joined in updating ANSI’s1982 standard for safety levels with respect to human exposure to RFsignals. More than 120 scientists, engineers and physicians fromuniversities, government health agencies and industries developed thisupdated standard after reviewing the available body of research. In 1993,the Federal Communications Commission (FCC) adopted this updatedstandard in a regulation. In August 1996, the FCC adopted hybrid standardconsisting of the existing ANSI/IEEE standard and the guidelines publishedby the National Council of Radiation Protection and Measurements (NCRP).Body-Worn OperationTo maintain compliance with FCC RF exposure guidelines, if you wear ahandset on your body, use the Sprint supplied or approved carrying case,holster or other body-worn accessory. Use of non-Sprint approvedaccessories may violate FCC RF exposure guidelines.For more information about RF exposure, visit the FCC Web site atwww.fcc.gov.
