MAINTAINING SAFE USE OF AND ACCESS TO
YOUR PHONE

Do Not Rely on Your Phone for Emergency Calls

Mobile phones operate using radio signals, which cannot
guarantee connection in all conditions. Therefore you should
never rely solely upon any mobile phone for essential
communication (e.g., medical emergencies). Emergency
calls may not be possible on all cellular networks or when
certain network services or mobile phone features are in use.
Check with your local service provider for details.

Using Your Phone While Driving

Talking on your phone while driving (or operating the
phone without a hands-free device) is prohibited in some
jurisdictions. Laws vary as to specific restrictions.
Remember that safety always comes first.

Following Safety Guidelines

To operate your phone safely and efficiently, always follow
any special regulations in a given area. Turn your phone
off in areas where use is forbidden or when it may cause
interference or danger.

Using Your Phone Near Other Electronic Devices

Most modern electronic equipment is shielded from radio
frequency (RF) signals. However, RF signals from wireless
phones may affect inadequately shielded electronic
equipment. RF signals may affect improperly installed or
inadequately shielded electronic operating systems or
entertainment systems in motor vehicles. Check with the
manufacturer or their representative to determine if these
systems are adequately shielded from external RF signals.
Also check with the manufacturer regarding any equipment
that has been added to your vehicle. Consult the
manufacturer of any personal medical devices, such as

3

pacemakers and hearing aids, to determine if they are
adequately shielded from external RF signals.

Note: Always turn off the phone in healthcare facilities,
and request permission before using the phone near
medical equipment.

Turning Off Your Phone Before Flying

Turn off your phone before boarding any aircraft. To
prevent possible interference with aircraft systems, the U.S.
Federal Aviation Administration (FAA) regulations require
you to have permission from a crew member to use your
phone while the plane is on the ground. To prevent any
risk of interference, FCC regulations prohibit using your
phone while the plane is in the air.

Turning Off Your Phone in Dangerous Areas

To avoid interfering with blasting operations, turn your
phone off when in a blasting area or in other areas with
signs indicating two-way radios should be turned off.
Construction crews often use remote-control RF devices to
set off explosives. Turn your phone off when you’re in any
area that has a potentially explosive atmosphere. Although
it’s rare, your phone and accessories could generate
sparks. Sparks can cause an explosion or fire, resulting in
bodily injury or even death. These areas are often, but not
always, clearly marked. They include:

Fueling areas such as gas stations.

•

Below deck on boats.

•

Fuel or chemical transfer or storage facilities.

•

Areas where the air contains chemicals or particles

•

such as grain, dust, or metal powders.

Any other area where you would normally be advised

•

to turn off your vehicle’s engine.

Note: Never transport or store flammable gas, flammable
liquids, or explosives in the compartment of your vehicle
that contains your phone or accessories.

Restricting Children’s Access to Your Phone

Your phone is not a toy. Do not allow children to play with it
as they could hurt themselves and others, damage the
phone or make calls that increase your invoice.

USING YOUR PHONE WITH A HEARING
AID DEVICE

When some wireless phones are used with certain hearing
devices (including hearing aids and cochlear implants),
users may detect a noise which can interfere with the
effectiveness of the hearing device. Some hearing devices
are more immune than others to this interference noise,
and phones also vary in the amount of interference noise
they may generate. ANSI standard C63.19 was developed
to provide a standardized means of measuring both
wireless phone and hearing devices to determine usability
rating categories for both.

Ratings have been developed for mobile phones to assist
hearing device users find phones that may be compatible
with their hearing device. Not all phones have been rated
for compatibility with hearing devices. Phones that have
been rated have a label located on the box.

has an M4/T4 rating.

These ratings are not guarantees. Results will vary
depending on the user’s hearing device and individual type
and degree of hearing loss. If a hearing device is
particularly vulnerable to interference noise; even a phone
with a higher rating may still cause unacceptable noise
levels in the hearing device. Trying out the phone with your
hearing device is the best way to evaluate it for your
personal needs.

M-Ratings:

requirements for hearing aid compatibility and are likely to
generate less interference to hearing devices than unrated

Phones rated M3 or M4 meet FCC
