About the MDW 9010
Introduction
Congratulations on the purchase of your new TransTalk™ 9000 Digital Wireless System
MDW 9010 Wireless Telephone. MDW stands for Multi-line Digital Wireless. This product
was designed to AT&T’s high standards for innovation, reliability, and convenience.
The MDW 9010 phone is wireless; the telephone line cord to the phone was eliminated. This
provides flexibility, so that you may not require additional telephone wiring when you move
into a new building, or change the phone’s location in an existing building. The phone can
be located as required. All you need is an electrical outlet, and a test check to make sure
that the handset is in range of its matching radio module.
The phone is portable, so there is no handset cord. This portability lets you move about
your work area or home with freedom, without giving up the features of a corded phone.
The handset communicates through a matching radio module, not the battery charger
where the handset sits for charging. 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 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.
A carrier (also known as a backplane) is required in order to use multiple wireless phones
within the same zone (area of coverage). Holding up to six radio modules, a carrier
synchronizes radio signals for proper operation of multiple phones, ensuring consistent
voice quality and range. Multiple carriers can be linked to support up to 18 wireless
phones in a single zone; linked carriers are automatically synchronized with each other.
As a special feature, a spare battery pack can be stored in the battery charger, allowing for
extended phone usage. For convenience, a headset can be connected to the phone to allow
hands-free conversation.
Introduction 1-1

This booklet describes MDW 9010 telephone installation. Also included with the phone is
a Telephone Quick Reference card that contains information about displays and controls
on the handset and the battery charger.
After you have installed your MDW 9010 phone and understand the controls and displays,
use the programming and call handling instructions that come with your communications
system; follow the user instructions for the phone type identified below:
For this communications system... Use the instructions for a...
PARTNER® MDW 9000 phone.
MERLIN®, MERLIN Plus, and MERLIN II 5-button phone.
MERLIN LEGEND® 10-button ATL set.
System 25 10-button ATL set.
System 75, System 85, and DEFINITY®* 7303s set.
NOTE:
The MDW 9010 phone is fully compatible with the PARTNER family of communications
systems. For the remaining communications systems, however, you must carefully
note the functional differences between your wireless phone and the phone type
identified in the table, as listed in Chapter 6, “MDW 9010 Compatibility.”
Privacy Information
The MDW 9010 phone is designed to protect the privacy and security of your voice
conversation. The set uses continuously changing radio frequencies and digital encoding
techniques to make it impossible for eavesdropping to occur through the use of commer-
cially available analog radio scanners.
* For DEFINITY G3V3 systems, you can administer the system for the MDW 9000 telephone (rather than a
7303s set) and follow the user’s instructions in the MDW 9000 Wireless Telephone User’s Guide, order
number 555-230-768.

2-6 Installing the MDW 9010

Positioning a Single Radio Module or Carrier(s)
All of your MDW 9010 handsets and their corresponding radio modules operate within a
single zone of coverage:
The range depends on your particular operating environment. For indoor use, intervening
walls will reduce the phone’s range. Try to stay away from concentrations of structural
metal, such as steel and aluminum, and reinforced concrete.
IMPORTANT:
The MDW 9010 phone has a built-in testing feature that you can use before
installation to help determine proper placement of the radio module. To perform
the test, all you need is an electrical outlet for the radio module and a charged
battery pack in the handset (you do not need a communications system switch/
control unit). Refer to “Wireless Test Mode” later in this chapter for details.
General Positioning Rules
Before you install the radio module or carrier(s), note the following rules regarding location
and use. Failure to follow these rules will result in poor performance of your MDW
9010 phone system.
■Position the radio module or carrier(s) in a central location, relative to the handset(s)
usage area. For convenience, you may want to place the radio module or carrier(s) in
the same room, and on the same wall, as your communications system switch/control
unit. If your switch/control unit is located in a remote location, you may have to run a
telephone line cord from your switch/control unit to the centrally positioned radio module
or carrier(s). The maximum distance is 1,000 feet (333 m) of 26-gauge cable.
Installing the MDW 9010 2-7

■
■
■
■
■
■
At least 6 feet (2 m) is required between the radio module or carrier(s) and the communi-
cations system switch/control unit.
The radio module or carrier(s) should be placed high on the wall for optimum voice
quality and range. Allow at least 6 inches (15.2 cm) of space between the top of the
antenna on the radio modules and the ceiling.
The radio module or carrier(s) should never be installed above a drop, suspended
level ceiling.
The radio module or carrier(s) should not be within 6 feet (2 m) of equipment with
microprocessors such as answering machines, personal computers, and fax
machines; electromagnetic equipment such as electric motors; or electrical main
power feeds, junction boxes, circuit-breaker panels, fuse boxes, or 220-volt
power lines.
The radio module or carrier(s) should not share the same power line as equipment with
microprocessors such as answering machines, personal computers, and fax machines;
or electromagnetic equipment such as electric motors.
If your communications system uses an uninterruptable power supply, such as a backup
generator, be sure to connect the radio module or carrier(s) to that power supply.
Additional rules for a single radio module only:
■Installing a single radio module on a shelf or desk is not recommended, because it
greatly reduces the range and quality of the transmission.
■Install a single radio module within 3 feet (1 m) of either side of, and within 6 to 8 feet
(2 to 2.6 m) above, a properly grounded 3-prong electrical outlet that is not controlled
by an on/off switch.
■You can install a single radio module in a remote location using a telephone line cord
to connect the radio module to the communications system switch/control unit. IROBs
must be used for out-of-building installations.
Additional rules for installing one or more carriers:
■Install carrier(s) within 15 feet (5 m) of either side of, and within 6 to 8 feet (2 to 2.6 m)
above, a properly grounded 3-prong electrical outlet that is not controlled by an on/off
switch.
■Choose a location where handset users will not approach the carrier(s) within a radius
of 6 feet (1.8 m) for 1 or 2 carriers or 10 feet (3.1 m) for 3 carriers.
■Carrier(s) cannot be exposed outdoors to the elements.
■When installing multiple carriers:
–Install multiple carriers 1 foot (0.3 m) optimally to 4 feet (1.2 m) apart.
–Install multiple carriers on the same horizontal axis (do not install one carrier
higher or lower than another).
–Install the control carrier as the leftmost carrier, using only the expansion cables
provided.
–There must always be a radio module in slot 6 of the control carrier.
Go to one of the following sections:
■If Installing one MDW 9010 phone, go to “Installing a Single Radio
Module.”
■Otherwise, go to “Setting the Power Level.”
2-8 Installing the MDW 9010

Installing a Single Radio Module

Plug the power cord/AC adapter into a properly
grounded 3-prong wall outlet that is not controlled
by an on/off switch.
CAUTION: Never connect or disconnect
the telephone line cord while the radio
module is plugged into the wall outlet.
Go to “Installation Self-Test.”
2-10 Installing the MDW 9010

Setting the Power Level
If you are installing one or more carriers in a strip mall, high-rise office building, or similar
environment, the MDW 9010 phones may interfere with other wireless products in use.
■If this is the case, you may need to adjust the range of the carriers to prevent
overlapping with the other wireless products; follow the instructions in this section.
■If this is not the case, skip this section and go to “Setting the Control/Expansion DIP
Switch.”
You may adjust the range by setting each carrier’s power DIP switch, located in slot 2:
