Interference in Vehicles
Please note that because of possible interference to electronic equipment, some vehicle manufacturers
forbid the use of mobile phones in their vehicles unless a hands-free kit with an external antenna is included in
the installation.
Explosive Environments
Gas Stations and Explosive Atmospheres
In locations with potentially explosive atmospheres, obey all posted signs to turn off wireless devices such as your
phone or other radio equipment.
Areas with potentially explosive atmospheres include fueling 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
Power off your mobile phone or wireless device when in a blasting area or in areas posted power off “two-way
radios” or “electronic devices” to avoid interfering with blasting operations.
