Guidelines for Safe and Efficient Use

Important:  Read This Information Before Using Your Handhold Portable Cell-
            ular Telephone.

First introduced in 1984, the handheld portable cellular telephone is one
of the most exciting and innovative products ever developed.  With it, you
can stay in contact with your office, your home, emergency services, and
many other places.

For the safe and efficient operation of your phone, observe the guidelines
in this manual.

Your cellular telephone is a radio transmitter and receiver.  When it is
ON it receives and sends out radio frequency (RF) energy.  The phone oper-
ates in the frequency range of 824 MHz to 894 MHz and employs commonly used
frequency modulation (FM) techniques. When you use your phone, the cellular
system handling your call controls the power level at which your phone
transmits.

Exposure to Radio Frequency Energy

In 1991 the Institute of Electrical and Electronics Engineers (IEEE), and
in 1992 the American National Standards Institute (ANSI), updated the 1982
ANSI Standard for safety levels with respect to human exposure to RF energy.
Over 120 scientists, engineers and physicians from universities, government
health agencies, and industry, developed this updated Standard after review-
ing the available body of research.  In March 1993 the Federal Communica-
tions Commission (FCC) proposed the adoption of this updated Standard.

Your phone is designed to comply with this updated Standard.  If you want
to limit RF exposure even further you may choose to control the duration
of your calls and operate your phone in the most power efficient manner.

Efficient Phone Operation

For your phone to operate at the lowest power level, and maintain satisfac-
tory call quality:

  Hold the phone as you would any other telephone.  While speaking directly
  into the mouthpiece, position the antenna 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.  Replace a damaged antenna
immediately.  If you need to replace your antenna, use only a manufacturer
approved antenna.  Otherwise, take your phone to a qualified service center
for repair.

Use only the supplied or approved antenna.  Unauthorized antennas, modifica-
tions or attachments could damage the phone and may violate FCC regulations.

To order an antenna, in the U.S. call 1-800-227-3663; outside the U.S.
contact your local retailer or call U.S. phone number 919-472-7908.

Driving

Check the laws and regulations on the use of cellular telephones in the
areas where you drive; always obey those laws.  Also, when using your phone
while driving, please:

  Give full attention to driving.

  Use hands-free operation, if available.

  Pull off the road and park (when driving conditions so require) before
  making or answering a call.

Electronic Devices

Most modern electronic equipment, (for example, equipment in hospitals and
cars), is shielded from RF energy.  However, RF energy from cellular tele-
phones may affect some electronic equipment.

Turn your phone OFF in health care facilities when regulations posted in
the areas instruct you to do so.  Always request permission before using
your phone near medical equipment.

RF energy may affect some electronic systems in motor vehicles.  Check with
your vehicle manufacturer's representative to be sure your phone will not
affect the electronic systems of your vehicle.

Aircraft

Turn your phone OFF before boarding any aircraft. To prevent possible inter-
ference 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 interference 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 could also damage the phone or make
calls that increase your telephone bills.

Blasting Areas

To avoid interfering with blasting operations, turn your phone 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.

Potentially Explosive Atmospheres

Turn your phone OFF when in any area with a potentially explosive atmos-
phere. 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, and areas
where the air contains chemicals or particles, such as grain, dust, or
metal powders.

Do not transport or store flammable gas, liquid, or explosives in any
compartment of your vehicle which contains your phone and accessories.

In the U.S. vehicles powered by 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

Operating Procedures

In the U.S. portable cellular telephones are subject to the rules and regu-
lations of the FCC.  Following these rules will help to eliminate confusion,
ensure the most efficient use of the existing frequencies, and result in a
smoothly functioning radio network.  The following offenses are punishable
by fine, imprisonment, or both:

  Use of profane, indecent, or obscene language.

  Transmission of a false distress signal or call.

  Willful or malicious interference with any other radio communications.

  Refusal to yield a channel or radio frequency when informed that it is
  needed for an emergency call.  Emergency calls have priority over all
  messages.

  Use of a cellular portable telephone in the Dominion of Canada, unless
  properly registered with the Industry Canada.

  Charging to an account without authorization to avoid payment for service.

  Adjustment of the equipment by anyone other than a qualified licensed
  technician.

Warranty Notification

Do not tamper with the Warranty Seal on the back of your phone.  Tampering
with this seal can void your warranty.  Do not attempt to take your phone
apart.  Doing so will void your warranty.  Your phone does not contain
consumer serviceable components. Service should only be performed by Author-
ized Service Centers.
