Radio Frequency (RF) Energy
Understanding How Your Phone Operates
Your phone is basically a radio transmitter and receiver. When it’s turned 
on, it receives and transmits radio frequency (RF) signals. When you use 
your phone, the system handling your call controls the power level. This 
power can range from 0.006 watts to 0.2 watts in digital mode.
Knowing Radio Frequency Safety
The design of your phone complies with updated NCRP standards 
described below.
In 1991-92, the Institute of Electrical and Electronics Engineers (IEEE) and 
the American National Standards Institute (ANSI) joined in updating ANSI’s 
1982 standard for safety levels with respect to human exposure to RF 
signals. More than 120 scientists, engineers and physicians from 
universities, government health agencies and industries developed this 
updated standard after reviewing the available body of research. In 1993, 
the Federal Communications Commission (FCC) adopted this updated 
standard in a regulation. In August 1996, the FCC adopted hybrid standard 
consisting of the existing ANSI/IEEE standard and the guidelines published 
by the National Council of Radiation Protection and Measurements (NCRP).
Body-Worn Operation
To maintain compliance with FCC RF exposure guidelines, if you wear a 
handset on your body, use the Sprint supplied or approved carrying case, 
holster or other body-worn accessory. Use of non-Sprint approved 
accessories may violate FCC RF exposure guidelines.
