Potentially explosive environments

Switch off your device in any area with a potentially explosive atmosphere and obey all 
signs and instructions. Potentially explosive atmospheres include areas where you would 
normally be advised to turn off your vehicle engine. Sparks in such areas could cause 

an explosion or fire resulting in bodily injury or even death. Switch off the device near 

gas pumps at service stations. Observe restrictions on the use of radio equipment in fuel 
depots, storage and distribution areas; chemical plants; or where blasting operations are 
in progress. Areas with a potentially explosive atmosphere are often, but not always, 
marked. They include below deck on boats, chemical transfer or storage facilities, 
vehicles using liquefied petroleum gas (such as propane or butane), and areas where the 
air contains chemicals or particles such as grain, dust or metal powders. 

Additional safety information

Your device and its enhancements may contain small parts. Keep them out of the reach 

of small children.
