Since t here are no known risks from exposure t o RF em issions from

wireless phones, t here is no reason t o believe t hat accessories t hat claim

t o shield t he head from t hose em issions reduce risks. Som e product s t hat

claim t o shield t he user from RF absorpt ion use special phone cases, while

ot hers involve not hing m ore t han a m et allic accessory at t ached t o t he

phone. St udies have shown t hat t hese product s generally do not w ork as

advert ised. Unlike " hand- free" kit s, t hese so- called " shields" m ay int erfere

wit h proper operat ion of t he phone. The phone m ay be forced t o boost it s

power t o com pensat e, leading t o an increase in RF absorpt ion. I n

February 2002, t he Federal t rade Com m ission ( FTC) charged t wo

com panies t hat sold devices t hat claim ed t o prot ect wireless phone users

from radiat ion wit h m aking false and unsubst ant iat ed claim s. According t o

FTC, t hese defendant s lacked a reasonable basis t o subst ant iat e t heir

claim .

Radio frequency energy ( RF) from wireless phones can int eract wit h som e

elect ronic devices. For t his reason, FDA helped develop a det ailed t est

m et hod t o m easure elect rom agnet ic int erference ( EMI ) of im plant ed

cardiac pacem akers and defibrillat ors from wireless t elephones. This t est

m et hod is now part of a st andard sponsored by t he Associat ion for t he

Advancem ent of Medical inst rum ent at ion ( AAMI ) . The final draft , a j oint

effort by FDA, m edical device m anufact urers, and m any ot her groups,

was com plet ed in lat e 2000. This st andard will allow m anufact urers t o

ensure t hat cardiac pacem akers and defibrillat ors are safe from wireless

phone EMI . FDA has t est ed wireless phones and helped develop a

volunt ary st andard sponsored by t he I nst it ut e of Elect rical and Elect ronic

Engineers ( I EEE) . This st andard specifies t est m et hods and perform ance

requirem ent s for hearing aids and wireless phones so t hat no int erference

occurs when a person uses a com pat ible phone and a com pat ible hearing

aid at t he sam e tim e. This st andard was approved by t he I EEE in 2000.

FDA cont inues t o m onit or t he use of wireless phones for possible

int eractions wit h other m edical devices. Should harm ful int erference be

found t o occur, FDA will conduct t est ing t o assess t he int erference and

work t o resolve t he problem .
