Implanted medical devices
Manufacturers of medical devices recommend a minimum
separation of 15.3 centimeters (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
•
centimeters (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.
Your mobile device model complies with FCC rules governing
hearing aid compatibility. These require a M3 microphone or
higher value. Your device M-value is shown on the box. 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
whether your hearing aid will work with this device. More
information on accessibility can be found at
www.nokiaaccessibility.com.
Setting for telecoil hearing aid users.
This device includes a setting for direct connection to telecoil-
equipped hearing aids. When both the telecoil hearing aid (T
switch) and the phone telecoil are activated, using the device
with the aided ear will provide a direct connection for audio
through your hearing aid. The quality of sound depends on
the type of hearing aid used. You should test the device with
the telecoil setting activated to determine whether your
audio performance improves. Using the telecoil hearing-aid
setting consumes additional battery power.

Additional safety information

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 refueling 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.

Emergency calls

Important: This device operates using radio signals,
wireless networks, landline networks and user-programmed
functions. If your device supports voice calls over the internet
(internet calls), activate both the internet calls and the
cellular phone. The device may attempt to make emergency
calls over both the cellular networks and through your
internet call provider if both are activated. Connections in all
conditions cannot be guaranteed. You should never rely
solely on any wireless device for essential communications
like medical emergencies.
