Nokia 3720 - Manual (Page 47)

• Hold the wireless device to the ear opposite the medical
device to minimise 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 accessories. 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: 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 will 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.
To make an emergency call:
1 If the device is not on, switch it on. Check for adequate
signal strength. Depending on your device, you may
also need to complete the following:
• Insert a SIM card if your device uses one.
• Remove certain call restrictions you have
activated in your device.
• Change your profile from offline or flight profile
mode to an active profile.
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.
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 organisation
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.
