Section 13: 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.
The energy levels associated with radio frequency energy, 
including both radio waves and microwaves, are not great 
enough to cause ionization of atoms and molecules. Therefore, 
RF energy is a type of non-ionizing radiation. Other types of 
non-ionizing radiation include visible light, infrared radiation 
(heat), and other forms of electromagnetic radiation with 
relatively low frequencies.
