Avoid areas with potentially explosive atmospheres include fueling areas such as lower
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 marked with signs, but not always.
Electromagnetic 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 radio frequency (RF) energy.
Pacemakers
The Health Industry Manufacturers Association recommends that you maintain a minimum separation
of 6 inches (15 cm) 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
Other Medical Devices
If you use any other personal medical device, consult the manufacturer of your device to determine if it
is adequately shielded from external RF energy. Your physician may be able to assist you in obtaining
this information.

Campus installations and warehouse facilities that use vehicles such as forklifts or golf carts should abide
by these guidelines when using wireless telephones:
