Potentially Explosive Atmospheres - Nokia 3110 User Manual

Hearing Aids
Some digital wireless phones may interfere with some hearing aids. In the event of
such interference, you may want to consult your service provider.
Other Medical Devices
Operation of any radio transmitting equipment, including cellular phones, may in-
terfere with the functionality of inadequately protected medical devices. Consult
a physician or the manufacturer of the medical device to determine if they are ad-
equately shielded from external RF energy or if you have any questions. Switch off
your phone in health care facilities when any regulations posted in these areas in-
struct you to do so. Hospitals or health care facilities may be using equipment that
could be sensitive to external RF energy.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic sys-
tems in motor vehicles (e.g. electronic fuel injection systems, electronic anti-skid
(anti-lock) braking systems, electronic speed control systems, air bag systems).
Check with the manufacturer or its representative regarding your vehicle. You
should also consult the manufacturer of any equipment that has been added to
your vehicle.
Posted Facilities
Switch your phone off in any facility where posted notices so require.

Potentially Explosive Atmospheres

Switch off your phone when in any area with a potentially explosive atmosphere
and obey all signs and instructions. Sparks in such areas could cause an explosion
or fire resulting in bodily injury or even death.
Users are advised to switch off the phone when at a refuelling point (service sta-
tion). Users are reminded of the need to observe restrictions on the use of radio
equipment in fuel depots (fuel 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; ve-
hicles using liquified petroleum gas (such as propane or butane); areas where the air
contains chemicals or particles, such as grain, dust or metal powders; and any other
area where you would normally be advised to turn off your vehicle engine.
Vehicles
Only qualified personnel should service the phone, or install the phone in a vehicle.
Faulty installation or service may be dangerous and may invalidate any warranty
which may apply to the unit.
