About TransTalk™ 9000 Products
Congratulations on the purchase of your new TransTalk 9000 Digital Wireless System
MDW 9031 Pocketphone. MDW stands for "Multi-Line Digital Wireless." The MDW 9031
Pocketphone is the latest addition to the TransTalk 9000 family of wireless products,
which also includes the MDW 9000 Telephone, the MDW 9010 Telephone and the
MDW 9030P Pocketphone. All of these phones are designed to Lucent Technologies' high
standards for convenience, reliability, and innovation.
TransTalk 9000 products are designed to work with your communications system
(PARTNER®, PARTNER II, PARTNER Plus, PARTNER Advanced Communications System,
MERLIN®, MERLIN II, MERLIN Plus, MERLIN LEGEND®, System 25, System 75, System
85, or DEFINITY®) to provide wireless flexibility.
What Is a Wireless Phone?
A wireless phone has no handset cord and no telephone line cord, so it is portable. This
portability lets you move around freely, without giving up the features of a wired phone.
With a wireless phone, you can make and receive calls even when you are away from
your desk, thus remaining accessible and responsive to your customers and coworkers
as you move around your work area. Time-sensitive work issues will not need to wait until
you are back at your desk, and you can reduce the number of (sometimes costly) phone
calls you must return.
TransTalk 9000 System
Your wireless phone’s handset is linked with your communications system through a
matching radio module, not through the battery charger where the handset sits for charg-
ing. Each handset can be used only with the radio module packaged with the handset. The
handset and the radio module each have the same unique security code and serial number
(on the bottom of the radio module and inside the battery compartment of the handset) to
identify the matching pair. And there is built-in and secure automatic registration between
the handset and radio module, so that your system is ready to use after powering up.
Your TransTalk system may have from 1 to 24 wireless phones. In order to use multiple
wireless phones within the same zone (area of coverage), you also need a carrier (also
known as a backplane). A carrier holds up to six radio modules, and synchronizes radio
Introduction 1-1

To insert the battery pack, insert the tab on the battery
signals for proper operation of multiple phones, ensuring consistent voice quality and
range. If you have a key system (for example, PARTNER or MERLIN). you can link up to
three carriers supporting up to 18 wireless phones in a single zone; if you have a PBX
system (for example, DEFINITY), you can link up to four carriers, supporting up to 24
wireless phones in a single zone. Linked carriers are automatically synchronized with
each other.
The TransTalk 9000 system enables you to use several different phone and carrier models
in the same zone, but there are some compatibility issues to consider. You need to know
the following:
■
■
The name of the MDW phone (9000, 9010, 9030P, or 9031), located in the battery
compartment of the handset. (For an MDW 9000 phone, you also need to know the
Apparatus Code, also located in the battery compartment of the handset.)
The model number of your carrier, located on the left side of the carrier.
The following illustrations show which phone models and carriers can be used together:

About the MDW 9031 Pocketphone
The MDW 9031 Pocketphone is not only wireless, but it is also lightweight and pocket-
sized. A removable carrying clip and a lanyard are provided with the handset. You can
use either the clip or the lanyard for hands-free portability. The MDW 9031 also has a
headset connector to accommodate an optional headset.
You can be notified of an incoming call by either an alerter (which rings) or a vibrator, or
both. There is a five-line, user-activated backlighted display that shows information you
would see on a wired system phone’s display (with the exception of the time ), icons
representing various handset functions (such as the alerter and the vibrator), and the
status of up to 12 telephone lines. The MDW 9031 provides Redial, Hold, Mute, Transfer,
and Conference buttons, and provides the capability to program additional features on
unused line buttons.
Privacy Information
The MDW 9031 Pocketphone is designed to protect the privacy and security of your voice
conversation. The phone uses continuously changing radio frequencies and digital
encoding techniques to make it impossible for eavesdropping to occur through the use of
commercially available analog radio scanners.
Where Can You Use Your Pocketphone?
The MDW 9031 Pocketphone can be used in most typical office buildings, in warehouses,
malls, and even in outdoor areas such as loading docks. The location of the radio
module greatly affects the performance of the MDW 9031. Read the "Positioning a
Radio Module or Carrier(s)" section in Chapter 2 to determine the best place to
install the radio module. Repeat the tests several times with the radio module positioned
in a different location each time. To perform the tests, all you need is an electrical outlet
for the radio module and a charged battery pack in the handset.

Spare Battery and Headset
One nickel metal hydride battery pack, which provides up to 3 hours of talk time, comes
with your MDW 9031 Pocketphone. For extended phone usage, you should purchase an
additional battery pack. If you require full business-day use, you can purchase an
extended battery pack. Although thicker and heavier than the standard battery pack, the
extended battery pack provides 8–9 hours of talk time when fully charged. You can store
the extra battery pack in the Spare battery compartment of the battery charger. Then
when the battery pack in the handset is low, you can switch battery packs.
To help you answer calls, an optional Supra® 9031 headset or a Radium (over the ear)
headset can be attached to a quick-disconnect adapter cord, which you can insert into

Important Safety Instructions
This book contains instructions related to safety labels on the product:
The exclamation point within an equilateral triangle is intended to alert the
user to the presence of important operating and maintenance (servicing)
instructions in the literature accompanying the product.
WARNING indicates the presence of a hazard that can cause severe or fatal
personal injury if the hazard is not avoided.
CAUTION indicates the presence of a hazard that will or can cause minor
personal injury or property damage if not avoided.
This phone is designed to provide trouble-free performance without any special mainte-
nance procedures. To reduce the risk of accidental damage:
■
■
■
■
Keep the phone in an area free of dust, smoke, and moisture; do not block the air
vents by placing objects on top of the radio module.
Do not place the phone or battery charger near a heating duct, radiator, or other heat
source, and do not drop or expose it to excessive shock or vibration.
Unplug the battery charger, radio module, or carrier if its power cord is damaged, if
liquid is spilled into it, or if its housing becomes cracked or otherwise damaged.
To clean your phone, wipe the outside housing with a soft, dust-free cloth. If absolutely
necessary, you may use a cloth slightly dampened with a mild soap and water solu-
tion. Dry quickly with a soft cloth.
CAUTION:
Your phone contains sensitive electronic parts. Never submerge it in any kind of
liquid, and never use liquid or aerosol cleaners, detergents, alcohols, solvents,
abrasive cleaners, or an excessive amount of water when cleaning the housing and
faceplate. To do so could result in irreparable damage.
Installing the MDW 9031 Pocketphone 2-1

Guidelines for Safe and Efficient Operation
Your wireless telephone is a radio transmitter and receiver. When the phone is turned on,
it receives and sends out radio frequency (RF) energy. The phone operates in the fre-
quency range of 902–928 MHz. Your hand-held wireless telephone uses the digital TDD
mode. The power is transmitted in bursts at a 200 Hz pulsed repetition rate. The peak
envelope transmit power is 325 mW or less.
Exposure to Radio Frequency Energy
The design of your wireless telephone complies with the latest Institute of Electrical and
Electronic Engineers (IEEE) and the American National Standards Institute (ANSI) safety
levels with respect to human exposure to RF energy. Of course, if you would like to limit
RF exposure even further, you may choose to control the duration of your calls.
Cardiac Pacemakers
CAUTION:
The MDW 9031 handset is a radio device and, like all radio devices, should not
be placed next to a pacemaker.
Preliminary studies performed at the US Food and Drug Administration (FDA) and else-
where have shown that when digital cellular telephones are placed very close to im-
planted cardiac pacemakers, interference with the operation of the implanted pacemaker
can occur. These preliminary studies show that interference does not occur when there is
a reasonable distance between the telephone and the implanted pacemaker and stops
when the phone is turned off or moved so that it is more than 6 inches (15 cm) from the
pacemaker. Digital cellular telephones operate at .6 W. TransTalk wireless telephones
operate at a lower peak power of 325 mW or less (100 mW, on an average).
Until more is known, the FDA suggests that people with pacemakers may want to take
some simple precautions when using or carrying digital wireless telephones to ensure that
there is ample distance between the digital wireless telephone and the pacemaker—by
not placing the phone next to the pacemaker implant (for example, in a shirt or a coat
pocket directly over the pacemaker implant) when the phone is on and ready to receive a
call and holding it to the ear opposite the side of the body where the pacemaker is
implanted when using the phone. Consult your physician or medical device manufacturer
to determine if additional precautions are necessary.
Hearing Aid Compatibility
Most electronic equipment, such as equipment in hospitals is shielded from RF energy.
However RF energy from wireless telephones may affect some electronic equipment.
Although the TransTalk wireless telephone is compatible with inductively-coupled hearing
aids, you should consult your physician or hearing aid manufacturer to determine if your
hearing aid is adequately shielded from external RF energy. The operation of inad-
equately shielded medical devices may be adversely affected when a portable wireless
telephone is operating in close proximity.
