Guidelines for Safe and Efficient Use
Some hearing aids might be disturbed by mobile phones. In the event of such
disturbance, you may want to consult your service provider, or call the
customer services line to discuss alternatives.
•
Turn off your mobile phone before boarding any aircraft.
•
Do not use it on the ground without crew permission.
To prevent interference with communication systems, you must not use your
mobile phone while the plane is in the air.
Turn off your mobile phone when in a blasting area or in areas posted “turn off
two-way radio” to avoid interfering with blasting operations. Construction
crews often use remote control RF devices to set off explosives.
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.
•
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.
