138 Product and safety information
Medical devices
Operation of radio transmitting equipment, including wireless phones, may interfere
with the function of inadequately protected medical devices. Consult a physician or the
manufacturer of the medical device to determine whether they are adequately shielded
from external RF energy. Switch off your device when regulations posted instruct you to
do so. Hospitals or health care facilities may use equipment sensitive to external RF
energy.
Implanted medical devices
Manufacturers of medical devices recommend a minimum separation of 15.3 centimetres
(6 inches) between a wireless device and an implanted medical device, such as a
pacemaker or implanted cardioverter defibrillator, to avoid potential interference with
the medical device. Persons who have such devices should:
Always keep the wireless device more than 15.3 centimetres (6 inches) from the
•
medical device.
Not carry the wireless device in a breast pocket.
•
Hold the wireless device to the ear opposite the medical device.
•
Turn the wireless device off if there is any reason to suspect that interference is
•
taking place.
Follow the manufacturer directions for the implanted medical device.
•
If you have any questions about using your wireless device with an implanted medical
device, consult your health care provider.
Hearing aids
Some digital wireless devices may interfere with some hearing aids.
Hearing aids
Warning:
For hearing aid compatibility, you must turn off the Bluetooth connectivity.
Your mobile device model complies with FCC rules governing hearing aid compatibility.
These rules require an M3 microphone or higher value. The M-value, shown on the device
box , refers to lower radio frequency (RF) emissions. A higher M-value generally indicates
that a device model has a lower RF emissions level, which may improve the likelihood
that the device will operate with certain hearing aids. Some hearing aids are more
immune than others to interference. Please consult your hearing health professional to
determine the M-rating of your hearing aid and whether your hearing aid will work with
this device. More information on accessibility can be found at
www.nokiaaccessibility.com.
This device has been tested and rated for use with hearing aids for some of the wireless
technologies that it uses. However, there may be some newer wireless technologies used
in this device that have not been tested yet for use with hearing aids. It is important to
try the different features of this device thoroughly and in different locations, using your
hearing aid or cochlear implant, to determine whether you hear any interfering noise.
Consult your service provider about its return and exchange policies and for information
on hearing aid compatibility.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in
motor vehicles such as electronic fuel injection, electronic antilock braking, electronic
speed control, and air bag systems. For more information, check with the manufacturer
of your vehicle or its equipment.
Only qualified personnel should service the device or install the device in a vehicle. Faulty
installation or service may be dangerous and may invalidate your warranty. 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 accessories. Remember that air bags inflate
with great force. Do not place your device or accessories in the air bag deployment area.
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 and may be illegal.
Potentially explosive environments
Switch off your device in any area with a potentially explosive atmosphere. Obey all
posted instructions. Sparks in such areas could cause an explosion or fire resulting in
bodily injury or death. Switch off the device at refuelling points such as near gas pumps
at service stations. Observe restrictions 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 areas
where you would be advised to turn off your vehicle engine, below deck on boats,
chemical transfer or storage facilities and where the air contains chemicals or particles
such as grain, dust, or metal powders. You should check with the manufacturers of
vehicles using liquefied petroleum gas (such as propane or butane) to determine if this
device can be safely used in their vicinity.
