bag deployment area. If in-vehicle wireless equipment is improperly installed and the air bag
inflates, serious injury could result.
Using your device while flying in aircraft is prohibited. Switch off your device before
boarding an aircraft. The use of wireless teledevices in an aircraft may be dangerous to the
operation of the aircraft, disrupt the wireless telephone network, and may be illegal.

■ 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.

■ Emergency calls

Important: Wireless phones, including this device, operate using radio signals,
wireless networks, landline networks, and user-programmed functions. Because of
this, connections in all conditions cannot be guaranteed. You should never rely
solely on any wireless device for essential communications like medical
emergencies.
1. If the device is not on, switch it on. Check for adequate signal strength. Some networks
may require that a valid UIM card is properly inserted in the device.
