READ THIS INFORMATION BEFORE
USING YOUR HAND-HELD PORTABLE
CELLULAR TELEPHONE
First introduced in 1984, the hand-held portable cellular
telephone is one of the most exciting and innovative elec-
tronic products ever developed. With it you can stay in
contact with your office, your home, emergency services,
and others.
For the safe and efficient operation of your phone,
observe these guidelines.
Your cellular telephone is a radio transmitter and receiver.
When it is ON, it receives and also sends out radio fre-
quency (RF) energy. The phone operates in the frequency
rangeof 824MHzto 894MHzand employscommonly used
frequencymodulation (FM) techniques.Whenyou useyour
phone, the cellular system handling your call controls the
powerlevelat which your phonetransmits.Thepowerlevel
can range from 0.006 of a watt to 0.6 of a watt.
Exposure to Radio Frequency Energy
In1991the Institute of Electrical andElectronicsEngineers
(IEEE), and in 1992 the American National Standards
Institute(ANSI)updated the 1982ANSI Standard forsafety
levels with respect to human exposure to RF energy. Over
120scientists,engineers, and physicians fromuniversities,
government health agencies, and industry, after reviewing
the available body of research, developed this updated
Standard. In March, 1993, the Federal Communications
Commission (FCC) proposed the adoption of this updated
Standard.
The design of your phone complies with this updated
Standard. Ofcourse,if you wanttolimit RF exposureeven
further than the updated ANSI Standard, you may choose
tocontroltheduration of your calls and operateyourphone
in the most power efficient manner.
Efficient Phone Operation
For your phone to operate at the lowest power level,
consistent with satisfactory call quality, please observe the
following guidelines:
ii

If your phone has an extendable antenna, extend it fully.
Some models allow you to place a call with the antenna
retracted. However, your phone operates more efficiently
with the antenna fully extended.
Hold the phone as you would any other telephone. While
speakingdirectlyinto the mouthpiece, position theantenna
up and over your shoulder. Do not hold the antenna when
the phone is “IN USE”. Holding the antenna affects call
quality and may cause the phone to operate at a higher
power level than needed.
Antenna Care and Replacement
Do not use the phone with a damaged antenna. If a dam-
aged antenna comes into contact with the skin, a minor
burn may result. Replace a damaged antenna immedi-
ately. Consult your manual to see if you may change the
antenna yourself. If so, use only a manufacturer approved
antenna. Otherwise,takeyourphonetoaqualifiedservice
center for repair.
Useonlythesupplied or approved antenna. Non-approved
antennas, modifications, or attachments could impair call
quality, damage the phone, and violate FCC regulations.
Driving
Check the laws and regulations on the use of cellular
telephonesintheareaswhereyoudrive. Always obeythem.
Also, when using your phone while driving, please:
* give full attention to driving,
* use hands-free operation, if available, and
* pull off the road and park before making or
answering a call if driving conditions so require.
Electronic Devices
Most modern electronic equipment is shielded from RF
energy. However, RF energy from cellular telephones may
affect inadequately shielded electronic equipment.
iii

RF energy may affect improperly installed or inad-
equately shielded electronic operating and entertainment
systems in motor vehicles. Check with the manufacturer
or its representative to determine if these systems are
adequately shielded from external RF energy. You should
also check with the manufacturer of any equipment that
has been added to your vehicle.
Consult the manufacturer of any personal medical devices
(such as pacemakers, hearing aids, etc.) to determine if
they are adequately shielded from external RF energy.
Turn your phone OFF in health care facilities when any
regulations posted in the areas instruct you to do so.
Hospitals or health care facilities may be using equipment
that could be sensitive to external RF energy.
Aircraft
Turn your phone OFF before boarding any aircraft.
* Use it on the ground only with crew permission.
* Do not use it in the air.
To prevent possible interference with aircraft systems,
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 inter-
ference with cellular systems, FCC regulations prohibit
using your phone while the plane is in the air.
Children
Do not allow children to play with your phone. It is not a
toy. Children could hurt themselves or others (by poking
themselves or others in the eye with the antenna for
example). Children also could damage the phone, or
make calls that increase your telephone bills.
Blasting Areas
To avoid interfering with blasting operations, turn your unit
OFF when in a “blasting area” or in areas posted: “Turn off
two-way radio”.
Construction crews often use remote control RF devices
to set off explosives.
iv

Potentially Explosive Atmospheres
Turn your phone OFF when in any area with a
potentially explosive atmosphere. It is rare, but
your phone or its accessories could generate sparks.
Sparks in such areas could cause an explosion or fire
resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere 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; and any other area
where you would normally be advised to turn off your
vehicle engine.
Do not transport or store flammable gas, liquid, or
explosives in the compartment of your vehicle which
contains your phone or accessories.
Vehicles using liquefied petroleum gas (such as propane
or butane) must comply with the National Fire Protection
Standard (NFPA-58). For a copy of this standard, contact
the National Fire Protection Association, One Batterymarch
Park, Quincy, MA 02269, Attn: Publication Sales Division.
Pacemaker/ICD's
Research sponsored by the Wireless Technology Research,
LLC ("WTR"), indicates that some wireless telephones cause
interference with pacemakers.Accordingly, NECAmerica
endorses the following recommendations issued by the WTR:
Wireless phones should be kept at a safe distance from a
pacemaker. Existing data indicate that the greater the
distance between a pacemaker and a wireless phone, the
less risk of interference. These data further indicate that six
inches is the proper separation distance for minimal risk.
Practical steps to achieve this separation distance include:
• The wireless telephone should not be placed over the
pacemaker, such as in a breast pocket, when it is in the
"ON" position. (A phone is "ON" when power is being
supplied to the telephone by the battery.)
• The phone should be used at the ear opposite the
pacemaker.
NOTE: There is nothing in the comprehensive data to suggest
that bystanders with pacemakers would be at risk of
interference from others who are using wireless phones.
