Hearing aids
Some digital wireless devices may interfere with some hearing aids. If interference occurs,
consult your service provider.

■ Potentially explosive environments

Switch off your device when 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 at refuelling
points such as 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 clearly 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.
