Usage guidelines:  All about performance and safety.

Keeping tabs on signal strength.

The voice quality of your Sprint PCS Phone will always be at its best when
the antenna is fully raised.  If you're inside a building, reception may
be better near a window.

The quality of each call you make or receive depends on the signal
strength in your area.  Your phone will inform you of the current strength
by displaying a number of bars next to the signal strength icon.  The more
bars displayed, the stronger the signal.

Understanding Power Save mode.

If you're trying to use your phone in an area where there is no signal,
the Power Save feature will automatically activate to conserve battery
power when you've been unable to pick up a signal for 15 minutes.  If your
phone is on, it will periodically recheck service availability, or you can
do so yourself manually by pressing any key.  A message will be displayed
on the screen any time Power Save has been activated.

Understanding how your phone operates.

Your Sprint PCS Phone is basically a radio transmitter and receiver.  When
it's turned on, it receives and transmits radio frequency (RF) signals.
Your phone operates in the Frequency range of 1.9 GHz.  When your phone is
in use, the system handling your call controls the power level.

Radio frequency safety.

In 1991-1992, the institute of Electrical and Electronics Engineers (IEEE)
and the American National Standards Institute (ANSI) joined in updating
ANSI's 1982 standard for safety levels with respect to human exposure to
RF signals.  More than 120 scientists, engineers and physicians from
universities, government health agencies and industries developed this
updated standard after reviewing the available body of research.  In 1993,
the Federal Communications Commission (FCC) adopted this updated standard
in a regulation.  In August 1996, the FCC adopted a hybrid standard
consisting of the existing ANSI/IEEE standard and the guidelines published
by the National Council of Radiation Protection and Measurements (NCRP).

The design of the Sprint PCS Phone complies with these updated standards.
Of course, if you want to limit RF exposure even further than the updated
standard, you can choose to control the duration of your calls and operate
your phone in the most power-efficient manner.

Maintaining your phone's peak performance.

To operate your phone properly -- that is to maintain safe and
satisfactory service -- you should follow these rules:

  For best reception, extend the antenna fully.

  Hold the phone with the antenna up and over your shoulder.

  Do not hold the phone antenna at any time.

  Do not use the phone with a damaged antenna.

  Speak directly into the mouthpiece.

Avoid exposing your phone and accessories to rain or liquid spills.  If
your phone does get wet, turn the power off immediately and remove the
battery pack.  If it is inoperable, you should return it to a Sprint PCS
Center or call Sprint PCS Customer Care for service.

Allow only authorized personnel to service your phone and its accessories.
Faulty service may invalidate the warranty.

Protecting your battery

For best battery performance, you should follow these guidelines:

  Only use Samsung-approved batteries (model numbers CSB-1900 and
  CEB-1900) and cigarette lighter adapter, desktop and travel chargers
  (model numbers CCL-1900, CDT-1900 and CTC-1900).  These chargers are
  designed to maximize battery life.  Using other batteries or chargers
  may invalidate your warranty and may cause damage as well.

  To avoid damage, charge the battery only in temperatures that range from
  32 to 104 degrees F (0 to 40 degrees C).

  Do not use the battery charger in direct sunlight or in high humidity
  areas, such as the bathroom.

  Never dispose of the batteries by incineration.

  Keep the metal contacts at the top of the battery clean.

  Do not attempt to disassemble or short-circuit the battery.

  You may need to recharge the battery if it has not been used for a
  long period of time.

  Condition your battery once a month.

  Replace the battery when it no longer provides acceptable performance.
  It can be recharged hundreds of times before it will need to be
  replaced.

  Do not store the battery in high-temperature areas for long periods of
  time.

Using your phone while driving.

Talking on the phone while you're driving may divert your attention from
the road and is illegal in some states.  Remember, safety comes first.

When using your Sprint PCS Phone in the car:

  Focus on driving, not talking.

  Use your hands-free car kit (optional accessory).

If you must use the phone while driving, please use Speed Dial and Any Key
Answer modes.

FAILURE TO FOLLOW THESE INSTRUCTIONS MAY LEAD TO SERIOUS PERSONAL INJURY
AND POSSIBLE PROPERTY DAMAGE.

Disposal of batteries.

You can return your unwanted Samsung batteries to your nearest Samsung
Service Center.  For the Samsung Service Center nearest you, call
1-888-987-HELP (U.S. only).

Note:  In some areas, the disposal of rechargeable batteries in household
       or business trash may be prohibited.

Following safety guidelines.

To operate your phone safely and efficiently, you should always follow any
special regulations in a given area, and 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 PCS telephones may affect inadequately
shielded electronic equipment.

RF signals may affect improperly installed or inadequately 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 signals.  You should 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
pacemakers and hearing aids) to determine if they are adequately shielded
from external RF signals.

Turn off the phone in health care facilities and request permission before
using the phone near medical equipment.

Turn off your phone before flying.

You should turn off your Sprint PCS Phone before boarding any aircraft.
To prevent possible interference with aircraft systems, 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.

Restricting children's access to your phone.

Your Sprint PCS phone is not a toy, and should not be played with by
children.  They could hurt themselves and others, damage the phone or make
calls that increase your telephone bills.

Turn off your phone in dangerous areas.

To avoid interfering with blasting operations, you should turn off your
phone when in a blasting area or in other areas with signs indicating that
two-way radios should be turned off.  Construction crews often use remote
control RF devices to set off explosives.

Turn off your phone when you are in any area with a potentially explosive
atmosphere.  It is rare, but your phone or its accessories could generate
sparks.  Sparks could cause an explosion or a 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 that contains your phone or accessories.

CAUTIONS:  Any changes or modifications to your Sprint PCS Phone not
           expressly approved in this document could void your warranty
           for this equipment and void your authority to operate this
           equipment.  Only use approved batteries, antennas and chargers.
           The use of any other type will invalidate the warranty.

FCC notice.

The phone may cause TV or radio interference if used in close proximity to
receiving equipment.  The FCC can require you to stop using the telephone
if such interference cannot be eliminated.

And finally, 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.
