8 Guidelines for Safe and Efficient Use
Note! The time required to discharge a battery varies based on
the type of battery and the number and duration of
your calls.
Completely discharge the battery and fully charge it,
three times in succession to, complete the battery
conditioning procedure.
FDA Consumer Update
FDA has been receiving inquiries about the safety of
mobile phones, including cellular phones and PCS
phones.
The following summarizes what is known – and what
remains unknown – about whether these products can
pose a hazard to health, and what can be done to mini-
mize any potential risk. This information may be used to
respond to questions.
Why the concern?
Mobile phones emit low levels of radiofrequency energy
(i.e., radiofrequency radiation) in the microwave range
while being used. They also emit very low levels of
radiofrequency energy (RF), considered non-significant,
when in the stand-by mode. It is well known that high
levels of RF can produce biological damage through
heating effects (this is how your microwave oven is able
to cook food). However, it is not known whether, to
what extent, or through what mechanism, lower levels of
RF might cause adverse health effects as well. Although
some research has been done to address these questions,
no clear picture of the biological effects of this type of
radiation has emerged to date. Thus, the available sci-
ence does not allow us to conclude that mobile phones
are absolutely safe, or that they are unsafe. However, the
available scientific evidence does not demonstrate any
adverse health effects associated with the use of mobile
phones.
What kinds of phones are in question?
Questions have been raised about hand-held mobile
phones, the kind that have a built-in antenna that is
positioned close to the user’s head during normal tele-
phone conversation. These types of mobile phones are of
concern because of the short distance between the
phone’s antenna – the primary source of the RF – and
the person’s head. The exposure to RF from mobile
phones in which the antenna is located at greater dis-
tances from the user (on the outside of a car, for exam-
ple) is drastically lower than that from hand-held
phones, because a person’s RF exposure decreases rapidly
with distance from the source. The safety of so-called
“cordless phones,” which have a base unit connected to
the telephone wiring in a house and which operate at far
lower power levels and frequencies, has not been ques-
tioned.
How much evidence is there that hand-held mobile
phones might be harmful?
Briefly, there is not enough evidence to know for sure,
either way; however, research efforts are on-going. The
