Section 14: Health and Safety Information 
This section outlines the safety precautions associated with 
using your phone. The terms “mobile device” or “cell phone” 
are used in this section to refer to your phone. Read this 
information before using your mobile device
Exposure to Radio Frequency (RF) 
Signals 
The U.S. Food and Drug Administration (FDA) has published 
information for consumers relating to Radio Frequency (RF) 
exposure from wireless phones. The FDA publication 
includes the following information: 
Do cell phones pose a health hazard? 
Many people are concerned that cell phone radiation will 
cause cancer or other serious health hazards. The weight of 
scientific evidence has not linked cell phones with any health 
problems. 
Cell phones emit low levels of Radio Frequency (RF) energy. 
Over the past 15 years, scientists have conducted hundreds 
of studies looking at the biological effects of the radio 
frequency energy emitted by cell phones. While some 
researchers have reported biological changes associated 
with RF energy, these studies have failed to be replicated. 
The majority of studies published have failed to show an 
association between exposure to radio frequency from a cell 
phone and health problems. 
The low levels of RF cell phones emit while in use are in the 
microwave frequency range. They also emit RF at 
substantially reduced time intervals when in the stand-by 
mode. 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. 
The biological effects of radio frequency energy should not 
be confused with the effects from other types of 
electromagnetic energy. 
Very high levels of electromagnetic energy, such as is found 
in X-rays and gamma rays, can ionize biological tissues. 
Ionization is a process where electrons are stripped away 
from their normal locations in atoms and molecules. It can 
permanently damage biological tissues including DNA, the 
genetic material.
