Operational Warnings
Potentially Explosive Atmospheres
Turn off your handset prior to entering any area with a potentially explosive atmosphere. Do not remove,
install, or charge batteries in such areas. Sparks in a potentially explosive atmosphere can cause an explosion or
fire resulting in bodily injury or even death.
The areas with potentially explosive atmospheres referred to above include fueling areas such as below decks on
boats, fuel or chemical transfer or storage facilities, areas where the air contains chemicals or particles such as grain,
dust, or metal powders, and any other area where you would normally be advised to turn off your vehicle engine. Areas
with potentially explosive atmospheres are often but not always posted.
Batteries
All batteries can cause property damage and/or bodily injury, such as burns if a conductive material such as
jewelry, keys, or beaded chains touches exposed terminals. The conductive material may complete an electrical
circuit (short circuit) and become quite hot. Exercise care in handling any charged battery, particularly when
placing it inside a pocket, purse, or other container with metal objects.
Electro Magnetic Interference and Compatibility
Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed, or
otherwise configured for electromagnetic compatibility.
Facilities
To avoid electromagnetic interference and/or compatibility conflicts, turn off your handset in any facility
where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment that is
sensitive to external RF energy.
Pacemakers
The Health Industry Manufacturers Association recommends that a minimum separation of 6 inches (15 cm)
be maintained between a handheld, wireless-radio product and a pacemaker. These recommendations are
consistent with the independent research by, and recommendations of, Wireless Technology Research. Persons
with pacemakers should:
ALWAYS keep the handset more than 6 inches (15 cm) from their pacemaker when the handset is turned
ON.
Not carry the handset in a breast pocket.
Use the ear opposite the pacemaker to minimize the potential for interference.
Turn the handset OFF immediately if you have any reason to suspect that interference is taking place.
Hearing Aids
Some digital wireless handsets may interfere with some hearing aids. In the event of such interference, you may
want to consult your hearing-aid manufacturer to discuss alternatives.
