Areas with flammables and explosives
• Do not use the device where flammables or explosives are
stored (in a gas station, oil depot, or chemical plant, for
example). Using your device in these environments increases
the risk of explosion or fire. In addition, follow the instructions
indicated in text or symbols.
• Do not store or transport the device in containers with
flammable liquids, gases, or explosives.
Traffic security
• Observe local laws and regulations while using the device. To
reduce the risk of accidents, do not use your wireless device
while driving.
• Concentrate on driving. Your first responsibility is to drive safely.
• Do not hold the device while driving. Use hands-free
accessories.
• When you must make or answer a call, pull off the road safely
and park the vehicle first.
• RF signals may affect the electronic systems of motor vehicles.
For more information, consult the vehicle manufacturer.
• Do not place the device over the air bag or in the air bag
deployment area in a motor vehicle. Doing so may hurt you
because of the strong force when the air bag inflates.
• Do not use your device while flying in an aircraft or immediately
before boarding. Using wireless devices in an aircraft may
disrupt wireless networks, present a hazard to aircraft
operation, or be illegal.
