Important: Read This Information Before
Using Your Handheld Portable Telephone
Your handheld portable telephone lets you stay
in touch with your office, your home, emergency
services, and many other places while you
travel. For safe and efficient operation of your
phone, observe the guidelines in this manual.
Your telephone is a radio transmitter and
receiver. When it is ON, it receives and sends
out radio frequency (RF) energy. The phone
operates in the frequency ranges of 824 MHz to
894 MHz and 1850 MHz to 1990 MHz,
employing commonly used frequency
modulation (FM) techniques. When you use
your phone, the wireless system handling your
call controls the power level at which your
phone transmits.
Exposure to Radio Frequency Signals
Your wireless handheld portable telephone is a
low power radio transmitter and receiver. When
it is ON, it receives and also sends out radio
frequency (RF) signals.
In August, 1996, the Federal Communications
Commission (FCC) adopted RF exposure
guidelines with safety levels for handheld
wireless phones. Those guidelines are consistent
with the safety standards previously set by both
U.S. and international standards bodies:
•ANSI C95.1 (1992)*
•NCRP Report 86 (1986)*
•ICNIRP (1996)*
Those standards were based on comprehensive
and periodic evaluations of the relevant
scientific literature. For example, over 120
scientists, engineers, and physicians from
universities, government health agencies, and
industry reviewed the available body of
research to develop the ANSI Standard (C95.1).
The design of your phone complies with the
FCC guidelines (and those standards).
Antenna Care
Use only the supplied antenna or an approved
replacement antenna. Unauthorized antennas,
modifications, or attachments could damage the
phone and may violate FCC regulations.
Phone Operation
Normal Position
Hold the phone as you would
any other telephone, with the
antenna pointed up and over
your shoulder.
Tips on Efficient Operation
For your phone to operate most efficiently, do not
touch the antenna unnecessarily when the phone
is in use. Contact with the antenna affects call
quality and may cause the phone to operate at a
higher power level than otherwise needed.
Driving
Check the laws and regulations on the use of
wireless telephones in the areas where you drive.
Always obey them. Also, if using your phone
while driving, please:
•Get to know your wireless phone and its
features such as speed dial and redial.
•When available, use a handsfree device.
•Position your wireless phone within easy
reach.
•Suspend conversations during hazardous
driving conditions or situations.
•Do not take notes or look up phone numbers
while driving.
•Dial sensibly and assess the traffic; if possible,
place calls when you are not moving or before
pulling into traffic.
•Do not engage in stressful or emotional
conversations that may be distracting.
•Use your wireless phone to call for help.
•Use your wireless phone to help others in
emergencies.
•Call roadside assistance or a special wireless
non-emergency assistance number when
necessary.

Radiation Protection and Measurements; International
Commission on Non-Ionizing Radiation Protection

Not for commercial use
•Give full attention to driving.
•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 signals. However, certain electronic
equipment may not be shielded against the RF
signals from your wireless phone.
Pacemakers
The Health Industry Manufacturers Association
recommends that a minimum separation of six
inches (6") be maintained between a handheld
wireless phone and a pacemaker to avoid
potential interference with the pacemaker.
These recommendations are consistent with the
independent research by and recommendations
of Wireless Technology Research.
Persons with pacemakers:
•Should ALWAYS keep the phone more than
six inches from their pacemaker when the
phone is turned ON.
•Should not carry the phone in a breast
pocket.
•Should use the ear opposite the pacemaker
to minimize the potential for interference.
•Should turn the phone OFF immediately if
they have any reason to suspect that
interference is taking place.
Hearing Aids
Some digital wireless phones may interfere with
some hearing aids. In the event of such
interference, you may want to consult your
service provider (or call the customer service
line to discuss alternatives).
Other Medical Devices
If you use any other personal medical device,
consult the manufacturer of your device to
determine if they are adequately shielded from
external RF energy. Your physician may be able
to assist you in obtaining this information.
Turn your phone OFF in health care facilities
when any regulations posted in these areas
instruct you to do so. Hospitals or health care
facilities may be using equipment that could be
sensitive to external RF energy.
Posted Facilities
Turn your phone OFF in any facility where posted
notices so require.
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.” Obey all
signs and instructions.
Potentially Explosive Atmospheres
Turn your phone OFF when in any area with a
potentially explosive atmosphere and obey all
signs and instructions. 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 gasoline stations;
below deck on boats; fuel or chemical transfer or
storage facilities; vehicles using liquefied
petroleum gas (such as propane or butane); 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.
Aircraft
FCC regulations prohibit using your phone while
in the air. Turn your phone OFF before boarding
an aircraft.
Vehicles
RF signals may affect improperly installed or
inadequately shielded electronic systems in motor
vehicles. Check with the manufacturer or its
representative regarding your vehicle. You should
also consult the manufacturer of any equipment
that has been added to your vehicle.
Vehicles Equipped with an Air Bag
An air bag inflates with great force. DO NOT
place objects, including both 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.

New Batteries
The battery packaged with your phone is
not fully charged. To get maximum battery
capacity, you can use a multicharger to
condition the battery. To condition the battery,
you first charge it, and then you fully discharge
it, three times in succession. See Conditioning
a Battery on page 3.
Recycling Your Battery
Your phone manufacturer is a member of the
Rechargeable Battery Recycling Corporation
(RBRC), a non-profit public service organization
designed to assist in the recycling of
rechargeable NiCd batteries. Many areas
require the recycling of these types of batteries.
In the U.S., call 1-800-822-8837 to find out how
to recycle your battery. Outside the U.S.,
contact your local retailer for recycling
instructions.
Battery Use and Care
A rechargeable battery has a long service life if
treated properly. A new battery, or one that
has not been used for a long period of time,
should be conditioned, as described above,
before using your phone. If a multicharger was
packaged with your phone, the multicharger
has a battery conditioning function.
Avoid recharging a fully-charged or almost
fully-charged battery. This can result in the
memory effect, which causes the battery to
charge to less than its full capacity. If your
phone shuts off due to low battery power,
charge the battery within 24 hours for the
battery to reach full capacity.
•Do not leave your battery where it could be
subjected to extremely hot or cold
temperatures. This could reduce the battery's
capacity.
•Never let the metal contacts on the battery
touch another metal object. This could short-
circuit and damage the battery.
•Do not attempt to take a battery apart.
•Do not expose a battery to open flame. This
could cause the battery to explode.
•Turn your phone OFF before removing the
battery.
•Use only the AC/DC adapter supplied with
your battery charger. Using a different
adapter could be dangerous and will void your
phone warranty.
•Never charge a battery when the ambient
room temperature is below 50° F (10° C) or
above 105° F (40° C).
•Do not allow the battery to be placed into the
mouth. Battery electrolytes may be toxic if
swallowed.
Battery Life/Scanning
When your phone cannot locate your home calling
area or anther acceptable coverage provider, it
will display Scanning. This means the phone is
continuously searching for a channel to provide
service. You need to be aware that scanning uses
more battery life than normal operation of your
phone. Your phone’s battery life will be depleted
more quickly than normal if your phone
frequently performs the scanning function.
