Potentially Explosive Environments - Nokia N93 User Manual

• Not carry the device in a breast pocket
• Hold the device to the ear opposite the pacemaker
to minimize the potential for interference.
If you suspect interference, switch off your device, and
move the device away.
Hearing aids
Some digital wireless devices may interfere with some hearing
aids. If interference occurs, consult your service provider.
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
116
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, 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.
