[ 108 ]Radio Frequency (RF) SignalsYour wireless handheld portable telephone is a low-power radiotransmitter and receiver. When it is ON, it receives and sends out radiofrequency (RF) signals.In August 1996, the Federal Communications Commission (FCC) adoptedRF exposure guidelines that included safety levels for handheld wirelessphones. Those guidelines are consistent with safety standards previouslyset by both U.S and international standards bodies:• ANSI C95.1 (1992)*, NCRP Report 86 (1986)*, ICNIRP (1996)*, andRSS-102 issue 1.Those standards were based on comprehensive and periodic evaluationsof the relevant scientific literature. For example, over 120 scientists,engineers, and physicians from universities, government health agencies,and industry reviewed the available body of research to develop the ANSIStandard (C95.1).The design of your phone complies with the FCC guidelines (and thosestandards).For body worn operation, to maintain compliance with FCC RF exposureguidelines, use only Nokia approved accessories. When carrying the phonewhile it is on, attach the phone to the specific Nokia belt-clip or place thephone in the specific Nokia carrying cases that have been tested forcompliance.Use of non-Nokia-approved accessories may violate FCC RF exposureguidelines and should be avoided.*American National Standards Institute, National Council on RadiationProtection and Measurements; International Commission on Non-Ionizing Radiation Protection.
