Using this guide
Your G300 series phone operates on the GSM network which provides
fraud protection, short message service (SMS), integrated voice mail,
superior voice quality and clear, static-free sound. One of the most
important GSM advantages is the removable SIM (subscriber identity
module), which holds your personal information such as phone numbers,
missed calls, voice mail notifications and text messages.
Certain features included in this guide called Network Services are supplied
by wireless service providers. You must order a subscription to the services
from your home service provider to be able to use them. For a full list and
explanation of Network Services, please ask your service provider.
Some networks may provide you with Data & Fax services. To use these
special services the Contact Data kit is required (see Accessories list on
page 68). The Contact Data kit contains instructions for use, or contact
your service provider for details.

Safety information
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 Commissions (FCC) adopted
RF exposure guidelines with safety levels for hand-held 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)
*American National Standards Institute; National Council on Radiation Protection and
Measurements; International Commission on Non-Ionizing Radiation Protection
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 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.

17
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:
• Give full attention to driving - driving safely is your first responsibility.
• Use hands-free operation, if available.
• 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 (6”) inches 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
• If you have any reason to suspect that interference is taking place,
turn your phone OFF immediately
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.

18
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.
Posted Facilities
Turn your phone OFF in any facility where posted notices so require.
AIRCRAFT
FCC regulations prohibit using your phone while in the air.
Switch OFF your phone before boarding an aircraft.
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.
For 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.

19
Care and maintenance
This PCS telephone is the product of advanced engineering, design and
craftsmanship and should be treated with care. The suggestions below will
help you to enjoy this product for many years.
• Do not expose the phone to any extreme environment where the

See page 50 for more details.
Code supplied by the manufacturer
Phone lock code (4 digits)
This code is set to all zeros and can be reset. Once changed it cannot be
identified by the manufacturer over the phone. See page 60 for more
details.
It is strongly recommended that you remember and make yourself
familiar with the purpose and operation of these codes.
Emergency calls
In the U.S., provided the phone has GSM service, emergency calls can be
madebydialing 911.
Emergency calls can even bemadeif the phone isPIN
or electronically locked or call barred. In some countries the phone may
have to contain a valid SIM card in order to use local emergency numbers.
Mobile phones rely on wireless and landline networks which cannot be guaranteed in all
conditions. Therefore you should never rely solely on wireless phones for essential
emergency communications.
