In such a case, FDA could require the manufacturersof wireless phones to notify users of the health hazard andto repair, replace or recall the phones so that the hazard nolonger exists.Although the existing scientific data do not justify FDAregulatory actions, FDA has urged the wireless phoneindustry to take a number of steps, including thefollowing:• Support needed research into possible biological effects of RFof the type emitted by wireless phones;• Design wireless phones in a way that minimizes any RFexposure to the user that is not necessary for device function;and• Cooperate in providing users of wireless phones with the bestpossible information on possible effects of wireless phone useon human health.FDA belongs to an interagency working group of thefederal agencies that have responsibility for differentaspects of RF safety to ensure coordinated efforts at thefederal level.
