ATTENTION
Before Using the Phone:
It is necessary that you CHARGE your phone
battery fully before attempting to make or receive a call.
Battery Disposal:
DO NOT PLACE USED BATTERIES IN YOUR REGULAR
TRASH. THIS NICKEL-CADMIUM (Ni-Cd) BATTERY MUST
BE COLLECTED, RECYCLED OR DISPOSED OF IN AN
ENVIRONMENTALLY SOUND MANNER.
Battery Recommendations:
The NEC TalkTime MAX™ 920 cellular phone you have
purchased was designed to deliver quality performance and
provide you with years of use. In order to maintain optimum
performance, NEC recommends that only NEC Authentic
Accessories™ be used with the TalkTime phones.
Specifically, NEC recommends only the use of Nickel
Cadmium (NiCd) batteries with the TalkTime MAX™ 920
phone. Use of other batteries, such as Nickel Metal Hydride
(NiMH) may result in poor battery performance, and in some
cases, create a potential safety risk due to overheating of the
battery.
The incineration, landfilling or mixing of nickel-cadmium
(Ni-Cd) batteries with municipal solid waste stream is
PROHIBITED BY LAW in most areas.
Return this battery to a federal or state approved nickelcadmium (or “sealed lead”) battery recycler. This may be
where you purchased the battery or a local seller of
automotive batteries. In all states, call 1-800-822-8837,
except Minnesota if further disposal information is required.
In Minnesota, call 1-800-225-PRBA.
Contact local waste management officials for other
information regarding the environmentally sound collection,
recycling and disposal of this battery.
In-Vehicle Operation:
For In-Vehicle Operations, the phone battery must be
charged, since In-Vehicle Adapter Kits serve only as a trickle
battery charger.

IMPORTANT
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
electronic 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 frequency
(RF) energy. The phone operates 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. The power level
can range from 0.006 of a watt to 0.6 of a watt.
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, 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. Of course, if you want to limit RF exposure even
further than the updated ANSI Standard, 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,
consistent with satisfactory call quality, please observe the
following guidelines:
iii
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
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. If a
damaged antenna comes into contact with the skin, a minor
burn may result. Replace a damaged antenna immediately.
Consult your manual to see if you can change the antenna
yourself. If so, use only a manufacturer approved antenna.
Otherwise, take your phone to a qualified service center for
repair.
Use only the supplied 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
telephones in the areas where you drive. Always obey them.
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.
iv
RF energy 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 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 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 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.
Air Bags
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 bag deployment area. If invehicle wireless equipment is improperly installed and the air
bag inflates, serious injury could result.
v
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 that 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/ICDs
Research sponsored by the Wireless Technology Research,
LLC (“WTR”), indicates that some wireless telephones cause
interference with pacemakers. Accordingly, NEC America
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:
o 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.)
o 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.

ROAMING (SYSTEM SELECT)
Each cellular service area can have two cellular service
suppliers called carriers. One carrier is called the ‘non-
wireline’ or ‘A’ system and the other carrier is called the
‘wireline’ or ‘B’ system. Your phone is designed to work with
either or both carriers.The system priority feature allows you
to program your phone for optimum operation when in your
home serving area or when away from your home area. This
is called roaming. When you buy your phone, you may
register (receive a phone number) with either or both of your
PWR

local carriers. Contact the office of your home cellular phone
company for information about the roaming agreements they
have with other cellular phone companies. In some areas,
roaming telephones are automatically recognized by the
cellular system’s computer. In other areas, you must contact
the cellular phone operator before it can recognize your
phone. The company needs to know your telephone number,
your phone ESN (electronic serial number), and how you
plan to pay for your calls. There is usually an additional
charge for roaming calls.
Note: The ESN for your phone is located in the battery
compartment of the phone, and is comprised of the first
8 digits preceded by NEC’s company code of 189.
To Select the Roaming Mode:

This allows the phone to first search for a free channel
in the Home system. If the phone cannot find a free
channel, it searches the other system.
The ROAM indicator is displayed when the phone is using a
system other than your home system. The roam systems
your phone accesses can be specified through the use of
system identification management, referred to as SID
management. SID Management is described below.

Programming of your System ID numbers is accomplished
by your service provider and is only associated with NAM1.

VOICE MESSAGING SERVICE
Cellular Digital Messaging Service (CDMS), if available
through the cellular service provider in the area, is a voice
message service for the cellular customer. When a cellular
customer turns off or does not answer the cellular phone, or
when the customer is currently on a call, CDMS answers the
incoming call. The caller is provided with the option to leave
a voice mail message. The cellular phone user is notified of
messages through a voice mail message indication.
VOICE MAIL MESSAGE INDICATION
When an incoming caller leaves a message through the
cellular provider's digital messaging service, the cellular
phone user is notified by a voice mail message indication.
The type of voice mail message notification varies between
cellular service providers. Upon receiving a voice mail
message, the voice mail message indication is one of the
following: a phone beep and displayed “MAIL” indication, a
phone beep without a displayed indication, or a series of
beeps generated by the service provider and transmitted to
the phone user through the earpiece receiver when an
outgoing call is made. The displayed indication is shown
below.
If additional messages are received before the current voice
message information is retrieved, the voice mail message
number in the displayed indicator increases.
Voice messages can be retrieved from the messaging
service by following the service provider instructions for voice
message retrieval. Contact your service provider for
information on availability of voice messaging services and
for any additional information on voice mail messaging.
