Hospitals
Switch off your wireless device when requested to do so in hospitals, clinics or health care facilities.
These requests are designed to prevent possible interference with sensitive medical equipment.
Interference in cars
Please note that because of possible interference to electronic equipment, some vehicle
manufacturers forbid the use of devices in their vehicles unless an external antenna is included
in the installation.
Explosive environments
Petrol stations and explosive atmospheres
In locations with potentially explosive atmospheres, obey all posted signs to turn off wireless
devices such as your device or other radio equipment. Areas with potentially explosive
atmospheres include fuelling areas, 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.
Blasting caps and areas
Turn off your device or wireless device when in a blasting area or in areas posted turn off “two-
way radios” or “electronic devices” to avoid interfering with blasting operations.
