503-801-166— Issue 3 — October 1999  
2  Installing the MDW 9031/9031DCP
Pocket Phone
Positioning a Radio Module or Carrier(s)
Each of your handsets and its corresponding radio module operates within a single zone of coverage:
The range depends on your particular operating environment. For indoor use, walls between the handset and the 
radio module will reduce the phone’s range. Avoid concentrations of structural metal, such as steel and 
aluminum, and reinforced concrete.
Note:The MDW 9031/9031DCP Pocket Phone has a built-in testing feature 
that you can use before final installation to help determine proper 
placement of the radio module. To perform the tests, 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). 
The tests are described in “Using Wireless Test Mode” in Chapter 3.
General Positioning 
RulesFailure to observe the following rules regarding location and use will result in 
poor performance of your MDW 9031/9031DCP Pocket Phone.
•Position the radio module or carrier(s) in a central location, relative to the 
handset(s) usage area, leaving at least 6 feet (1.8 m) between the radio module or 
carrier(s) and the communications system switch/control unit or other wired 
phones. 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 line cord maximum length is 1,000 feet 
(305 m) of 26-gauge cable.
•Place the radio module or carrier(s) high on the wall for optimum voice quality 
and range. Allow 6 to12 inches (15.2 to 30.5 cm) of space between the top of the 
antenna on the radio module and the ceiling.

•Never install the radio module or carrier(s) above a drop, suspended ceiling.
•Do not locate the radio module or carrier(s) within 3 feet (0.9 m) of any large 
metal object, and be sure no metal objects are in the line of sight to the operating 
area of the handset.
•Do not locate the radio module or carrier(s) within 6 feet (1.8 m) of 
equipment with microprocessors, such as answering machines, personal 
computers, and fax machines; control units, communications system 
switches, or other phones (especially speakerphones); competing radio 
devices such as wireless bar-code scanners; electromagnetic equipment such 
as electric motors; or electrical main power feeds, junction boxes, circuit-
breaker panels, fuse boxes, or 220-volt power lines.
•Be sure the radio module or carrier(s) does 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 uninterruptible power supply, such as a 
backup generator, you may want to connect the radio module or carrier(s) to that 
power supply.
Additional Rules for 
Installing 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 (0.9 m) of either side of, and within 6 to 
8 feet (1.8 to 2.4 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. 
!CAUTION:
A radio module cannot be installed outdoors.

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 (1.8 
to 2.4 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 m) for 3 
carriers.
•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.
~Slot 6 of an 117A3 control carrier must always contain a radio module to pass 
the synchronization signal to the next carrier.
!CAUTION:
Carrier(s) cannot be installed outdoors.
Installing a Single Radio Module
•Install a single radio module high on a wall, leaving 6 to 12 inches (15.2 to 
30.5 cm) between the top of the antenna and the ceiling.
•See “Key Components” earlier in this chapter for additional picture detail.
To install a single radio module:
1  Perform the tests described in “Using Wireless Test Mode” in Chapter 3 to 
determine the optimal placement of the radio module. To perform the tests, all 
you need is an electrical outlet for the radio module and a charged battery pack in 
the handset.
2  Check to be sure the radio module’s power cord is unplugged from the wall outlet 
before continuing.Go to “Using Wireless Test Mode” in Chapter 3.

3  Detach the rubber feet from the shipping card. Apply them to marked areas on the 
underside of the radio module.
4  Place the wall-mounting plate against the wall. Choose a location backed by a 
wooden stud (if unavailable, use toggle bolts instead of the supplied wood 
screws). Lightly tap a nail into the wall to start holes. Then screw the plate flush 
to the wall. Place the radio module over the plate, then slide it downward to lock 
it into place. 
Note: Do not remove the plastic cap covering the radio module’s card edge.

2  Installing the MDW 9031/9031DCP
Pocket Phone
Note:The RADIO LED also may light upon installation; however, since the 
RADIO LED has no significance during installation, ignore its operation.
The RADIO LED indicates a connection between the handset and the 
radio module; it lights when the handset is being used as long as the 
battery pack in the handset is charged. 
Understanding Carriers
When you install more than one radio module in a single zone, you must mount the radio modules in a carrier, so 
that their signals will be synchronized. A carrier can hold up to six radio modules. The MDW 9031/9031DCP 
Pocket Phone is designed to work with either of two carrier models: Model 117A3, and Model 117A4.
Note:If you currently own a Model 117A1, 117A1A, or 117A2 carrier, Lucent 
Technologies will replace it with a Model 117A3 or Model 117A4 at no 
charge.
If you want to install more than six radio modules, you will need more than one carrier. Systems configured as 
key systems (for example, PARTNER or MERLIN) can accommodate up to 18 radio modules (three carriers); 
PBX systems can accommodate up to 24 radio modules (four carriers).
In any multiple-carrier installation, the leftmost carrier acts as the control carrier, and the remaining carriers act 
as expansion carriers, passing along the synchronization signal from the control carrier. Multiple carrier 
installations require that you use Model 117A3 or Model 117A4 carriers, or both.
The Model 117A3 and Model 117A4 carriers are similar in general appearance, but the installation procedure for 
the two models differs somewhat. A label on the left side of the carrier identifies the carrier model number.
Understanding Your Model 117A3 Carrier
The installation of a Model 117A3 carrier differs in three ways from the installation of a Model 117A4 carrier:
•You may need to adjust the power DIP switch.
•You must set the Control/Expansion DIP switch.
•If you use the 117A3 as the control carrier, you must have a radio module 
installed in Slot 6 of that carrier in order to pass the synchronization signal on to 
the next carrier. If you are installing one model of carrier, go to either of the 
following sections:
•If installing a Model 117A3 carrier, go to “Understanding 
Your Model 117A3 Carrier.”
•If installing a Model 117A4 carrier, go to “Understanding 
Your Model 117A4 Carrier.”
If you are installing both carrier models, read both of these 
sections.

As the following illustration shows, each Model 117A3 carrier has two user-adjustable DIP switches—one in 
Slot 2 that controls the power levels, and another in Slot 4 that specifies whether this particular carrier is 
functioning as a control or an expansion carrier.
Go to either of the following sections:
•If you need to adjust the 117A3 carrier’s range to prevent 
overlapping with other wireless products, go to 
“Setting the 117A3 Carrier Power Level.”
•To skip that section, go to “Setting the 117A3 Carrier 
Control/Expansion DIP Switch.”

Setting the 117A3 
Carrier Power LevelIf your MDW 9031/9031DCP Pocket Phones are interfering with other wireless 
products in use or if you anticipate that they will, you can adjust the carrier’s range by 
setting each 117A3 carrier’s power DIP switch, located in Slot 2.
The power DIP switch must be adjusted while the carrier is without power and while 
Slot 2 is empty. You can adjust it before mounting the carrier on the wall.
