HOW WILL I KNOW IF MY HEARING AID WILL WORK WITH A PARTICULAR DIGITAL
WIRELESS PHONE?
You'll want to try a number of wireless phones so that you can decide which works the best with your
hearing aids. You may also want to talk with your hearing aid professional about the extent to which
your hearing aids are immune to interference, if they have wireless phone shielding, and whether your
hearing aid has a HAC rating.

FDA CONSUMER UPDATE
1. Do wireless phones pose a health hazard?
The available scientific evidence does not show that any health problems are associated with using
wireless phones. There is no proof, however, that wireless phones are absolutely safe. Wireless phones
emit low levels of radiofrequency energy (RF) in the microwave range while being used. They also emit
very low levels of RF when in the Home screen. Whereas high levels of RF can produce health effects
(by heating tissue), exposure to low level RF that does not produce heating effects causes no known
adverse health effects. Many studies of low level RF exposures have not found any biological effects.
Some studies have suggested that some biological effects may occur, but such findings have not been
confirmed by additional research. In some cases, other researchers have had difficulty in reproducing
those studies, or in determining the reasons for inconsistent results.
