Construction crews often use remote control RF devices to set off explosives.
Potentially Explosive Atmospheres
Turn off your mobile phone when in any area with a potentially explosive atmosphere. It is rare, but your phone or its accessories could generate sparks. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They include fuelling areas, such as petrol stations, below deck on boats, fuel or chemical transfer or storage facilities, and areas where the air contains chemicals or particles, such as grain, dust, or metal powders.
Do not transport or store flammable gas, liquid, or explosives in the compartment of your vehicle, which contains your mobile phone and accessories.
Power Supply
•Connect AC (Power supply) only to designated power sources as marked on the product.
•To reduce risk of damage to the electric cord, remove it from the outlet by holding onto the AC adapter rather than the cord.
•Make sure the cord is positioned so that it will not be stepped on, tripped over or otherwise subjected to damage or stress.
•To reduce risk of electric shock, unplug the unit from any power source before attempting to clean it.
•The charger must not be used outdoors or in damp areas.
Children
Do not allow children to play with your mobile phone since it contains small parts that could become detached and create a choking hazard.
