Hearing Aids
Some digital wireless phones may interfere with some hearing
aids. In the event of such interference, you may want to consult
your service provider.
Other Medical Devices
Operation of any radio transmitting equipment, including wire-
less phones, may interfere with the functionality of inadequately
protected medical devices. Consult a physician or the manufac-
turer of the medical device to determine if they are adequately
shielded from external RF energy or if you have any questions.
Switch off your phone in health care facilities when any regula-
tions posted in these areas instruct you to do so. Hospitals or
health care facilities may be using equipment that could be
sensitive to external RF energy.
Vehicles
RF signals may affect improperly installed or inadequately
shielded electronic systems in motor vehicles (e.g. electronic
fuel injection systems, electronic anti-skid (anti-lock) braking
systems, electronic speed control systems, air bag systems).
Check with the manufacturer or its representative regarding
your vehicle. You should also consult the manufacturer of any
equipment that has been added to your vehicle.
Posted Facilities
Switch your phone off in any facility where posted notices so
require.
Potentially Explosive Atmospheres
Switch off your phone when in any area with a potentially explo-
sive atmosphere and obey all signs and instructions. Sparks in
such areas could cause an explosion or fire resulting in bodily
injury or even death.
Users are advised to switch off the phone while at a refueling
point (service station). Users are reminded of the need to
observe restrictions on the use of radio equipment in fuel
depots (fuel storage and distribution areas), chemical plants
or where blasting operations are in progress.
Areas with a potentially explosive atmosphere are often but not
always clearly marked. They include below deck on boats;
chemical transfer or storage facilities; vehicles using liquefied
petroleum gas (such as propane or butane); 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.
