Section 10: 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.
