Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in motor
vehicles such as electronic fuel injection systems, electronic antiskid (antilock) braking systems,
electronic speed control systems, and air bag systems. For more information, check with the
manufacturer, or its representative, of your vehicle or any equipment that has been added.
Only qualified personnel should service the device or install the device in a vehicle. Faulty
installation or service may be dangerous and may invalidate any warranty that may apply to
the device. Check regularly that all wireless device equipment in your vehicle is mounted and
operating properly. Do not store or carry flammable liquids, gases, or explosive materials in
the same compartment as the device, its parts, or enhancements. For vehicles equipped with
an air bag, remember that air bags inflate with great force. Do not place objects, including
installed or portable wireless equipment in the area over the air bag or in the air 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 refueling
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 and areas where the air contains chemicals or particles such as grain, dust, or metal
powders. You should check with the manufacturers of vehicles using liquefied petroleum gas
(such as propane or butane) to determine if this device can be safely used in their vicinity.

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.
To make an emergency call:
1. If the device is not on, switch it on. Check for adequate signal strength.
Some networks may require that a valid SIM card is properly inserted in the device.
