118Health and safety information6. Do hands-free kits for wireless phones reduce risksfrom exposure to RF emissions?Since there are no known risks from exposure to RFemissions from wireless phones, there is no reason tobelieve that hands-free kits reduce risks. Hands-free kitscan be used with wireless phones for convenience andcomfort. These systems reduce the absorption of RFenergy in the head because the phone, which is the sourceof the RF emissions, will not be placed against the head.On the other hand, if the phone is mounted against thewaist or other part of the body during use, then that partof the body will absorb more RF energy. Wireless phonesmarketed in the U.S. are required to meet safetyrequirements regardless of whether they are used againstthe head or against the body. Either configuration shouldresult in compliance with the safety limit.7. Do wireless phone accessories that claim to shield thehead from RF radiation work?Since there are no known risks from exposure to RFemissions from wireless phones, there is no reason tobelieve that accessories that claim to shield the head fromthose emissions reduce risks. Some products that claim toshield the user from RF absorption use special phonecases, while others involve nothing more than a metallicaccessory attached to the phone. Studies have shown thatthese products generally do not work as advertised. Unlike“hand-free” kits, these so-called “shields” may interferewith proper operation of the phone. The phone may beforced to boost its power to compensate, leading to anincrease in RF absorption. In February 2002, the Federaltrade Commission (FTC) charged two companies that solddevices that claimed to protect wireless phone users fromradiation with making false and unsubstantiated claims.According to FTC, these defendants lacked a reasonablebasis to substantiate their claim.8. What about wireless phone interference with medicalequipment?Radio frequency energy (RF) from wireless phones caninteract with some electronic devices. For this reason, FDAhelped develop a detailed test method to measureelectromagnetic interference (EMI) of implanted cardiacpacemakers and defibrillators from wireless telephones.This test method is now part of a standard sponsored bythe Association for the Advancement of Medicalinstrumentation (AAMI). The final draft, a joint effort byFDA, medical device manufacturers, and many othergroups, was completed in late 2000. This standard will
