transmission of data files or messages may be delayed until
such a connection is available. Ensure the above separation
distance instructions are followed until the transmission is
completed.
Parts of the device are magnetic. Metallic materials may be
attracted to the device. Do not place credit cards or other
magnetic storage media near the device, because
information stored on them may be erased.
Medical devices
Operation of any radio transmitting equipment, including
wireless phones, may interfere with the functionality of
inadequately protected medical devices. Consult a
physician or the manufacturer of the medical device to
determine if they are adequately shielded from external RF
energy or if you have any questions. Switch off your device
in health care facilities when any regulations posted in
these areas instruct you to do so. Hospitals or health care
facilities may be using equipment that could be sensitive
to external RF energy.

							Implanted medical devices
Manufacturers of medical devices recommend that a
minimum separation of 15.3 centimeters (6 inches) should
be maintained 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 when
the wireless device is turned on.
●Not carry the wireless device in a breast pocket.
●Hold the wireless device to the ear opposite the medical
device to minimize the potential for interference.
●Turn the wireless device off immediately if there is any
reason to suspect that interference is taking place.
●Read and follow the directions from the manufacturer
of their 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. 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
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 refuelling 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
and areas 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:  Wireless phones, including this device,
operate using radio signals, wireless networks, landline

							networks, and user-programmed functions. Because of
this, connections in all conditions cannot be guaranteed.
You should never rely solely on any wireless device for
essential communications like medical emergencies.
To make an emergency call:
1. If the device is not on, switch it on. Check for adequate
signal strength.
Some networks may require that a valid SIM card is
properly inserted in the device.
2. Press the end key as many times as needed to clear the
display and ready the device for calls.
3. Enter the official emergency number for your present
location. Emergency numbers vary by location.
4. Press the call key.
If certain features are in use, you may first need to turn
those features off before you can make an emergency call.
Consult this guide or your service provider for more
information.
When making an emergency call, give all the necessary
information as accurately as possible. Your wireless device
may be the only means of communication at the scene of
an accident. Do not end the call until given permission to
do so.

							CERTIFICATION INFORMATION (SAR)
This mobile device meets guidelines for exposure to
radio waves.
Your mobile device is a radio transmitter and receiver. It is
designed not to exceed the limits for exposure to radio
waves recommended by international guidelines. These
guidelines were developed by the independent scientific
organization ICNIRP and include safety margins designed
to assure the protection of all persons, regardless of age
and health.
The exposure guidelines for mobile devices employ a unit
of measurement known as the Specific Absorption Rate or
SAR. The SAR limit stated in the ICNIRP guidelines is 2.0
watts/kilogram (W/kg) averaged over 10 grams of tissue.
Tests for SAR are conducted using standard operating
positions with the device transmitting at its highest
certified power level in all tested frequency bands. The
actual SAR level of an operating device can be below the
maximum value because the devic e  i s  d e s i g n e d  t o  u s e  o n l y
the power required to reach the network. That amount
changes depending on a number of factors such as how
close you are to a network base station. The highest SAR
value under the ICNIRP guidelines for use of the device at
the ear is 1.19 W/kg.
Use of device accessories and enhancements may result in
different SAR values. SAR values may vary depending on

							national reporting and testing requirements and the
network band. Additional SAR information may be
provided under product information at www.nokia.com.
