drastically lower because a person's RF exposure decreases rapidlywith increasing distance from the source. The so-called “cordlessdevices,” which have a base unit connected to the telephone wiring in ahouse, typically operate at far lower power levels, and thus produce RFexposures well within the FCC's compliance limits.Do devices pose a health hazard?The available scientific evidence does not show that any healthproblems are associated with using devices. There is no proof,however, that devices are absolutely safe. devices emit low levels ofradio frequency energy (RF) in the microwave range while being used.They also emit very low levels of RF when in the stand-by mode.Whereas high levels of RF can produce health effects (by heatingtissue), exposure to low level RF that does not produce heating effectscauses no known adverse health effects. Many studies of low level RFexposures have not found any biological effects. Some studies havesuggested that some biological effects may occur, but such findingshave not been confirmed by additional research. In some cases, otherresearchers have had difficulty in reproducing those studies, or indetermining the reasons for inconsistent results.What is FDA's role concerning the safety of devices?Under the law, FDA does not review the safety of radiation-emittingconsumer products such as devices before they can be sold, as it doeswith new drugs or medical devices. However, the agency has authorityto take action if devices are shown to emit radio frequency energy (RF)at a level that is hazardous to the user. In such a case, FDA couldrequire the manufacturers of devices to notify users of the healthHealth and safety information
