c. • Do not leave your battery where it may be subjected to
extremely hot or cold temperatures. This could reduce the
battery’s capacity.
• Do not let the metal contacts on the battery touch another
metal object such as keys in your pocket. This could short-
circuit and damage the battery.
• Do not attempt to take a battery apart.
• Do not expose a battery to open flame. This could cause the
battery to explode.
• Turn your phone OFF before removing the battery.
• Use only the AC/DC adapter supplied with your battery
charger. Using a different adapter could be dangerous and will
void your phone warranty.
• Never charge a battery when the ambient room temperature is
below 50°F (10°C) or above 105°F (40°C).
• Do not allow the battery to be placed into the mouth. Battery
electrolytes may be toxic if swallowed.
FDA Consumer Update
The U.S Food and Drug Administration (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 minimize 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 science
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 telephone 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 distances from the user
(on the outside of a car, for example) 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 questioned.
