Introduction

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 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 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 pocketsized. 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.

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 maintenance 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 solution. 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 frequency 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 elsewhere have shown that when digital cellular telephones are placed very close to implanted 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 inadequately shielded medical devices may be adversely affected when a portable wireless
telephone is operating in close proximity.

2-8 Installing the MDW 9031 Pocketphone

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.

IMPORTANT:
The MDW 9031 Pocketphone 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 "Wireless Test Mode" in Chapter 3.

General Positioning Rules
Failure to observe the following rules regarding location and use will result in poor
performance of your MDW 9031 Pocketphone.
■

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.

■

The radio module or carrier(s) should be placed high on the wall for optimum voice
quality and range. Allow 6–12 inches (15.2–30.5 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
ceiling.
Installing the MDW 9031 Pocketphone 2-9

■

The radio module or carrier(s) should not be within 3 feet (.9 m) of any large metal
object, and should not have metal objects in the line of sight to the operating area of
the handset.

■

The radio module or carrier(s) should not be 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.

■

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 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.
Go to "Wireless Test Mode" in Chapter 3.

2-10 Installing the MDW 9031 Pocketphone

Installing a Single Radio Module
■

Install high on wall, leaving 6–12 inches (15.2–30.5 cm) between antenna and ceiling

■

See "Key Components" earlier in this chapter for additional picture detail

Perform the tests described in "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.

Check to make sure the radio module’s power cord is unplugged from the wall outlet
before continuing.

Detach the rubber feet from the shipping card.
Apply them to marked areas on the underside
of the radio module.

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.)

Insert one end of the telephone line cord into
an extension jack or terminal/station connector
on your communications system switch/control unit
(refer to your communications system manual for the
proper location).

Installing the MDW 9031 Pocketphone 2-11

Insert the radio module’s power cord into the
side of the radio module. Insert the other end of
the telephone line cord into the bottom of the 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.

Single Radio Module Installation Self Test
Verify that the POWER and PASS LEDs on the radio
module light. If the radio module’s PASS LED does
not light:

Unplug the power cord/AC adapter from the
wall outlet.

Wait 15 seconds.

Plug it in again.

If the radio module’s PASS LED still does not light,
refer to Chapter 5, "Troubleshooting."

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.

2-12 Installing the MDW 9031 Pocketphone

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 Pocketphone is designed to work with any of three
carrier models: Model 117A1A, Model 117A3, and Model 117A4.

NOTE:
If you currently own a Model 117A2 carrier, Lucent Technologies will replace it with a
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.
If you are installing one model of carrier, go to one of the
following sections:
■

If installing a Model 117A3 carrier, go to "Understanding
Your Model 117A3 Carrier."

■

If installing a Model 117A3 carrier, go to "Understanding
Your Model 117A4 Carrier."

If you are installing both carrier models, read both of these
sections.

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.

Installing the MDW 9031 Pocketphone 2-13

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.

If you are installing one or more 117A3 carriers in a strip mall, high-rise office building, or
similar environment, the MDW 9031 Pocketphones may interfere with other wireless
products in use. If this is the case, you can adjust the range of the 117A3 carrier(s) to
prevent overlapping with the other wireless products.
Go to one of the following sections:
■

To adjust the 117A3 carrier’s range, go to "Setting the 117A3
Carrier Power Level."

■

To skip that section, go to "Setting the 117A3 Carrier
Control/Expansion DIP switch."

2-14 Installing the MDW 9031 Pocketphone

Setting the 117A3 Carrier Power Level
If your MDW 9031 Pocketphones 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.

Power
DIP Switch

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.
Use a nonmetallic, pointed object to set each carrier’s DIP switch according to the following table.

IMPORTANT:
You must set the DIP switch for all of the 117A3 carriers to the same setting.

Go to "Setting the 117A3 Carrier Control/Expansion DIP Switch."
Installing the MDW 9031 Pocketphone 2-15

Setting the 117A3 Carrier Control/Expansion DIP Switch
The Model 117A3 carrier can serve as either a control or an expansion carrier. Whether
you install one or more 117A3 carriers, you must set the Control/Expansion DIP switch in
Slot 4 of each 117A3 carrier to indicate which role that carrier is filling.

Control/Expansion
DIP Switch

Slot 4

The leftmost carrier, no matter what model number it is, must be the control carrier, and
the remaining carriers are expansion carriers. The control carrier acts as the "lead"
carrier—its transmit and receive patterns control the expansion carriers, ensuring that all
of the linked carriers function as a single system.
It is recommended that you determine which carrier is to be the control carrier, and which,
if any will be expansion carriers, and set the Control/Expansion DIP switch(es) before
mounting the carrier(s) on the wall.
Use a nonmetallic, pointed object to set each 117A3 carrier’s DIP switch according to the
following table.

2-16 Installing the MDW 9031 Pocketphone

IMPORTANT:
Only one carrier (the leftmost carrier) can be the control carrier; the other carriers must be
expansion carriers.

"Understanding Your Model 117A4 Carrier."

■

If you are installing a single 117A3 carrier, go to "Installing
a Single Carrier."

■

If you are installing multiple 117A3 carriers, go to "Installing
Multiple Carriers."

Installing the MDW 9031 Pocketphone 2-17

Understanding Your Model 117A4 Carrier
The Model 117A4 carrier differs from the 117A3 in that it does not require that Slot 6
contain a radio module in order to pass the signal from the control carrier to the next
carrier. It also does not have Power and Control/Expansion DIP switches to set. The
117A4 automatically adjusts its power level and senses whether it is being used as a
control or an expansion carrier.
As the following illustration shows, the 117A4 does have an additional LED located on the
right side of the carrier, the CONTROL/EXPANSION LED, used for determining whether
the cabling was installed correctly.

compare the OUT OF SYNC and CONTROL/
EXPANSION LEDs against the top three lines on the
"SYNC and CONTROL/EXP LED Codes" label.

If the OUT OF SYNC LED is lit, power down,
wait at least 15 seconds, and then repower the
carrier. If the LED is still lit, follow the suggestions in
the "Installation Problems" section of Chapter 5,
"Troubleshooting." If the LED is still lit, call for help
as described on the inside cover of this book.

If you are using a Model 117A4 carrier, verify
that the carrier’s CONTROL/EXPANSION LED
is lit and that its color is green. This is correct for a
single-carrier installation.

Verify the POWER and PASS LEDs on each
radio module are lit. If a radio module’s PASS
LED does not light, power down the carrier and the
module, wait 15 seconds, and repower the module
and then the carrier. If the PASS LED still does not
light, refer to Chapter 5, "Troubleshooting."

NOTE:
The RADIO LED also may light upon installation;

2-28 Installing the MDW 9031 Pocketphone

Installing Multiple Carriers
■

Install each carrier high on wall, leaving 6–12 inches (15.2–30.5 cm) between
antennas and ceiling

■

Install each carrier 1 foot (0.3 m) optimal to 4 feet (1.2 m) from its neighboring carrier
Never install or remove a radio module from a carrier that is plugged into a wall
outlet (hot insertion)

■

See "Key Components" earlier in this chapter for additional picture detail

■

Multiple-carrier installation involves several stages:
■

Mounting the carriers on the wall and cabling them

■

Installing a single radio module in each carrier

■

Installing the remaining radio modules

The most efficient method for installing carriers and their radio modules is to perform self
tests after each stage of the installation. This enables you to spot any problems at an early
stage, and avoid the necessity for reinstalling the components in order to solve problems.

Mounting and Cabling Multiple Carriers
Perform the tests described in "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.
If you are installing any 117A3 carriers and need to adjust the power setting to avoid
interference from other wireless products, see "Setting the 117A3 Carrier Power Level."
Also make sure you have set the Control/Expansion DIP switch correctly (see "Setting the
117A3 Carrier Control/Expansion DIP Switch").

Check to make sure the carrier’s power cord is
unplugged from the wall outlet before continuing.

Choose a location backed by a wooden stud for
the carrier (if unavailable, use toggle bolts
instead of the supplied wood screws).

IMPORTANT:
The leftmost carrier must be the control carrier; all
of the others are expansion carriers.
Place the carrier against the wall, leaving enough room
to the right for additional carrier(s) if applicable. Hold
the carrier straight; use a level if needed. Using a nail
or pencil, mark screw locations through the four wallmount holes. Start the screws, leaving the screw heads
protruding approximately ½" (12 mm) from the wall.
Repeat Steps 1 through 3 for each carrier,
leaving 1 foot (0.3 m) optimally to 4 feet (1.2 m)
between carriers.

Place the carrier over the screws, then slide it
downward to lock it into place. Be sure that the
leftmost carrier is the control carrier. Tighten the
screws. Repeat for each carrier.

Installing the MDW 9031 Pocketphone 2-29

Connect an expansion cable to the OUT jack of
the control carrier.

Insert the free end of the expansion cable into
the IN jack of the expansion carrier immediately to the right of the control carrier.

NOTE:
Although installing an expansion cable
into the wrong IN or OUT jack will not harm either
carrier, doing so causes all handsets to work
improperly and the OUT OF SYNC LED to light.

If you have a second expansion carrier:

a. Connect an expansion cable to the OUT jack
of expansion carrier #1.
b. Insert the free end of the expansion cable
into the IN jack of expansion carrier #2.
See "Key Components" earlier in this chapter for an
illustration of a four-carrier setup.

Plug an AC adapter cord into the left side of
each carrier.

2-30 Installing the MDW 9031 Pocketphone

Insert each carrier’s power cord into its AC
adapter.

If appropriate, you can wall-mount each AC adapter

Installing the MDW 9031 Pocketphone 2-31

Multiple Carrier Mounting and Cabling Self Test
Wait a few seconds after powering up the carriers, then verify that the red OUT OF
SYNC LEDs on all carriers are lit. This is normal when no radio modules have yet
been installed. The CONTROL/EXPANSION LEDs should also be lit and blinking:

■

Model 117A4 control carrier = Green blinking

■

Model 117A4 expansion carrier(s) = Green blinking

A Model 117A3 carrier has no CONTROL/EXPANSION LED, but the DIP switch in Slot 4
of the carrier must be set correctly to either Control or Expansion.
The following illustration shows the correct LED lights for a four-carrier installation
with no radio modules installed yet. This example installation has three 117A4
carriers—one acting as the control carrier and the other two acting as expansion
carriers—and one 117A3 carrier acting as an expansion carrier.

At this stage of your installation, the LEDs
displayed should match the third or sixth lines
of the SYNC and CONTROL/EXP LED Codes label,
depending on whether the carrier is the control or an
expansion carrier.

If the LEDs on your installation do not reflect
this pattern, there is probably a mistake in the
cabling. Power down the carriers and check that you
have followed Steps 6 through 8 in "Mounting and
Cabling Multiple Carriers" correctly. If you are still
having problems, see Chapter 5, "Troubleshooting."

If your LEDs match the pattern in the illustration,
you can feel confident that your carriers are
cabled correctly. Power down the carriers and go on
to "Installing a Single Radio Module in Each Carrier."

2-32 Installing the MDW 9031 Pocketphone

Installing a Single Radio Module in Each Carrier
Remove the plastic cap covering each radio
module’s card edge before inserting the radio
modules into the carriers.

Working from left to right, insert a radio module
into the first slot (Slot 1) of each carrier; hook
each radio module onto the mounting rod. Slowly
swing the radio module’s card edge into the card
edge connector on the back of the carrier. (Exception: use Slot 6 instead of Slot 1 for a Model 117A3
control carrier.)

IMPORTANT:
Slot 6 of a Model 117A3 control carrier must
always contain a radio module to pass the
synchronization signal to the next carrier.
A Model 117A4 carrier does not require Slot 6
to be filled.
When the card edge is fully seated, a snap lock
3 on the bottom of the radio module will engage.

Insert a telephone line cord into the bottom of
each radio module.

Installing the MDW 9031 Pocketphone 2-33

Slide the telephone line cords through the cable
manager slot on the left front of each carrier.

Power the carriers as follows:

If the carriers are plugged into...

Then...

One surge suppressor strip

Power the strip.
Result: All carriers will turn on simultaneously.

Wall outlets

Plug in the power for the Carriers in this order:

CAUTION:
Never connect or disconnect expansion cables or telephone line
cords, or insert or remove radio modules, while the carrier is
plugged into the wall outlet.
Keep in mind that a Model 117A3 control carrier must have a module in Slot 6 in order to
synchronize correctly with the remaining carrier(s).

2-34 Installing the MDW 9031 Pocketphone

Installation Self Test with a Single Radio Module in Each Carrier
Wait a few seconds after powering the carriers, then verify that the carriers’ OUT OF
SYNC LEDs are not lit.

The following illustration shows the correct LED lights for a four-carrier installation
with one radio module installed in each carrier. This example installation has three
117A4 carriers—one acting as the control carrier and the other two acting as expansion
carriers—and one 117A3 carrier acting as an expansion carrier.

When one radio module is present in each carrier, the red OUT OF SYNC LEDs will not be
lighted on any carrier, no matter which model. The other LEDs will be lighted as follows:
■

Model 117A4 control carrier CONTROL/EXPANSION LED = Green

■

Two Model 117A4 expansion carriers CONTROL/EXPANSION LED = Amber

■

The radio modules’ PASS and POWER LEDs = Green

The Model 117A3 expansion carrier has no CONTROL/EXPANSION LED, but the DIP
switch in Slot 4 of the carrier is set to Expansion.

At this stage of your installation, the LEDs
displayed should match the first or fourth
lines of the SYNC and CONTROL/EXP LED
Codes label, depending on whether the carrier
is the control or an expansion carrier.
(Keep in mind that a Model 117A3 carrier does
not have a CONTROL/EXPANSION LED.)

Installing the MDW 9031 Pocketphone 2-35

If an OUT OF SYNC LED is lit, power down,
wait at least 15 seconds, and then repower the
carriers in order from left to right, as described in
Step 7. If the LED is still lit, follow the suggestions in
the "Installation Problems" section of Chapter 5,
"Troubleshooting." If the LED is still lit, call for help
as described on the inside front cover of this book.

The PASS and POWER LEDs on all radio
modules should be lighted and green. If a radio
module’s PASS LED is not lighted:

a. Power down the carriers.
b. Unplug from the wall outlet the power
cord/AC adapter of the radio module
that did not light.
c. Wait 15 seconds.
d. Plug in the radio module’s power cord again.
e. Repower the carriers again, following the
proper left-to-right order.

If your LEDs match the pattern in the illustration
in Step 2, you can feel confident that the
carriers are cabled correctly and that the installed
radio modules are all functional. Power down the
carriers and go on to "Installing the Remaining
Radio Modules."

2-36 Installing the MDW 9031 Pocketphone

Installing the Remaining Radio Modules
Remove the plastic cap covering each radio
module’s card edge before inserting the radio
modules into the carriers.

Installing the MDW 9031 Pocketphone 2-43

Battery Charger
This section explains how to choose a location for the battery charger and install it. It also
explains how to insert and remove a battery pack.

Positioning the Battery Charger
The battery charger can be placed on a desk, or it can be mounted on a wall. Before you
install the battery charger, note the following considerations:
■

Locate the battery charger within 5 feet (1.6 m) of a properly grounded 3-prong
electrical outlet that is not controlled by an on/off switch.

■

If your communications system uses an uninterruptable power supply, such as a
backup generator, you may want to connect the battery charger to that power supply.

■

Do not locate the battery charger where it will be exposed to direct sunlight or water.

WARNING:
The rechargeable battery pack may contain elements that are harmful to the
environment (for example, nickel). Do not burn or puncture the battery. Like other
batteries of this type, if it is burned or punctured, it could release toxic material
that could cause injury. Do not dispose of it in household garbage. For information about recycling or proper disposal, consult your local solid waste (garbage)
collection or disposal organization.

Installing the Battery Charger
■

If you are wall-mounting the battery charger, follow Steps 1 through 7

■

If you are desk-mounting the battery charger, follow only Steps 1, 5, and 7

Check to make sure the battery charger’s power cord is unplugged from the wall outlet
before continuing. If you are desk-mounting, skip to Step 5.

To wall-mount, place the battery charger’s wall-mounting template (located on the
last page of this book) against the wall. Choose a location backed by a wooden
stud (if unavailable, use toggle bolts instead of the supplied wood screws). Hold the
template straight; use a level if needed.

Mark the locations for the two wall-mounting screws, and then remove the template
from the wall. Lightly tap a nail into the wall to start the holes.

Place the screw through the wall spacers so that the screw head nests in the
indentation on the spacer. Start the screws, and screw them in until the wall spacers
rest against the wall.

2-44 Installing the MDW 9031 Pocketphone

Insert the battery charger’s power cord/AC
adapter into the battery charger. If you are
desk-mounting the battery charger, skip to Step 7.

Place the keyhole-shaped openings in the back
of the battery charger over the screw heads
and wall spacers, then slide the battery charger
downward into the groove in the wall spacers to lock
it into place.

Plug the battery charger’s power cord/AC
adapter into a properly grounded 3-prong wall
outlet that is not controlled by an on/off switch.

Installing the MDW 9031 Pocketphone 2-45

Inserting a Battery Pack into
the Spare Battery Compartment
Slide the battery pack (or an optional extended battery pack) into the Spare battery
compartment until it is firmly seated with the back of the battery pack against the back of
the Spare battery compartment. Do not force the battery pack down. The battery pack
should slide easily into the slot.
Correct positioning of the battery pack in the charger is important to ensure proper
charging. The bottom end of either battery pack also has two small round holes that must
align with two guide pins on the bottom of the Spare battery compartment. When a

3-22 Using the MDW 9031 Pocketphone

Extending Battery Life
The battery charger will charge a battery pack in the handset if you simply insert the
handset in the battery charger’s handset cradle; however, the Refresh process fully
discharges the battery pack before recharging it, thereby ensuring the best possible
charge and the longest talk time.
"Memory effect" reduces a battery’s capacity, and can occur when you repeatedly
recharge a battery pack before it is fully discharged. The nickel metal hydride battery
pack shipped with your MDW 9031 is resistant to the memory effect. Even so, it is recommended that you refresh your battery pack at least once a week.
The following table shows how long refreshing takes, depending on how much charge is
left in the battery pack when you insert it into the charger and press the REFRESH button

time.
It is highly recommended that you purchase a second battery pack to use as a spare.
With the spare battery pack in the Spare battery compartment of the battery charger, you
are assured of always having a fresh, usable battery pack.

Using the MDW 9031 Pocketphone 3-23

Follow these steps to ensure an uninterrupted supply of power to your MDW 9031
Pocketphone:
■

If you have only one battery pack, be sure to refresh it at least once a week. You can
refresh it by:
–

Placing it in the Spare battery compartment of the battery charger.

–

Leaving it in the handset, placing the handset in the handset cradle of the battery
charger, and pressing the REFRESH button.

■

If you have two battery packs, exchange the packs between the handset and the
Spare battery compartment at least once a week, so that each battery pack is automatically refreshed. (Alternate the battery packs even if the handset battery never
flashes the Battery icon in the handset display to indicate a low battery condition.)

■

The average battery life for both the standard and the extended battery packs is
approximately one year, assuming that the battery is discharged and charged once a
day. If the battery packs are discharged and charged twice a day, the life expectancy
is approximately six months.

IMPORTANT:
Depending on the level of memory effect that the battery pack has, it is sometimes necessary to refresh the battery pack twice:
Insert the battery pack in the Spare battery compartment of the battery
charger and leave it there until the SPARE LED is steady green. Remove the
battery pack from the charger, then reinsert it, and leave it until the SPARE
LED is steady green a second time.
Or, with the battery pack in the handset, insert the handset in the handset
cradle, press REFRESH, and leave it there until the HANDSET LED is steady
green. Remove the handset from the handset cradle, then reinsert it, press
REFRESH again, and leave it until the HANDSET LED is steady green a second time.

Possible Causes
A competing radio
device (for example, a
wireless bar-code
scanner) has been
installed in the area.
Both products are
competing for the
same air space and
will conflict when both
are being used.

Possible Solutions
Place the handset in Wireless Test Mode
as described in Chapter 3. If the signal
strength and voice quality readings are
low, look for a newly installed radio
device nearby. Remove it or move your
handset’s matching radio module at least
6 feet (1.8 m) away from the potential
interference.

carrier.
For a multiple-carrier installation:
1. Verify that all expansion cables are fully
inserted in the correct IN and OUT jacks.
2. Check CONTROL/EXPANS1ON LEDs
for correct color (see "Understanding
the Model 117A4 Carrier" in Chapter 2).
3. Ensure that each carrier has at least
one Radio Module installed.
If the control carrier is a Model 117A3,
ensure that there is a Radio Module in
that carrier’s Slot 6.
4. Power down all carriers, wait 15

MDW 9031 Pocketphone Compatibility 6-1

NOTE:
The MDW 9031 Pocketphone is fully compatible with the PARTNER family of communication 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 on the previous page. Differences are summarized on the
following pages.
Some systems do not support display features. In these cases, the display is not
available; the MDW 9031 works as a nondisplay set.

Programming Features for PARTNER,
MERLIN, and MERLIN LEGEND Systems
On all PARTNER, MERLIN, and MERLIN LEGEND systems, you can assign a feature to an
available button (a button that does not have a line or another feature assigned to it):
1. To enter programming mode, turn on the handset, press  Intercom , then press  Feat/P 
followed by  0   0 .
to move the Selection rectangle to the row of line indica2. Press the Select button
tors containing the available button.
3. Press the Column button

under the button that you want.

4. Program the feature (using the procedure described in the manual for your PARTNER,
MERLIN, or MERLIN LEGEND communications systems).

NOTE:
Some features provide a visual indication in the handset display that the feature is
turned on. Be aware that if you turn off the handset while using one of these features,
you may forget that the feature is on. To verify the status of a such a feature, you can
simply press the
button to "wake up" the phone and activate the display.
5. To exit programming mode, press  Feat/P  followed by  0   0  or turn off the handset.

NOTE:
The above instructions do not apply to System 25, System 75, System 85, and
DEFINITY systems, because in those systems, features are assigned by the System
Administrator.

MERLIN Systems
■

■

On MERLIN II and MERLIN LEGEND systems, you must connect your wireless phone
to an available jack on either a 408 outside line/analog telephone module or a 008
analog telephone module.
Since the MDW 9031 does not have a speaker function, the Voice Announce feature
must be disabled. It is recommended that you use MERLIN 206/410/820 systems
installed with Feature Package 2 with your wireless phone, so that you can disable that
feature.

■

Since the MDW 9031 has no speaker function, it should not be assigned to a paging
group.

■

To program the Ringing Option feature, use the "triangle" and "rectangle" indicators
in the display as the equivalent of red and green LEDs, respectively.

■

For MERLIN II system users, if you program an Auto Intercom button, idle line preference
must be set to intercom.
If any of your incoming lines has the call waiting feature, use the Recall feature (letter "C" in
the display) and press it before you pick up a waiting call. You can dial  #   5   0  before you
pick up a waiting call on the following: MERLIN 206/410/820 systems only with Feature
Package 2, and all MERLIN Plus, MERLIN II, and MERLIN 1030/3070 systems. Pressing the
 On/Off  button disconnects the call.
The  Feat/P  button on the MDW 9031 allows you only to enter programming mode. It
does not work when using MERLIN LEGEND system features. To use MERLIN LEGEND system feature codes with this phone, program any available button as a System
Feature button. This enables you to use the wide array of MERLIN LEGEND system
features by turning the set on, pressing the System Feature button, and dialing the
appropriate " * " code number.
Note: MERLIN LEGEND does not support Caller ID and some other Display features
to Analog/Hybrid terminals, such as the MDW 9031.

Installing a Single Radio Module
Install high on wall, leaving at least 6–12 inches (15.2–30.5 cm) between antenna and ceiling

Check to make sure the radio module’s power cord is unplugged from the wall outlet
before continuing.

Detach the four rubber feet. Apply them to marked areas
on the underside of the radio module.

Comcode 108174764

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.)

Insert the radio module’s power cord into the side of the
radio module. Insert the telephone line cord into the
bottom of the radio module.

Insert the other end of the telephone line cord into an
existing wall jack or terminal/station connector on your
communications system switch/control unit (refer to your
communications system manual for the proper port location).

Plug the power cord/AC adapter into a properly grounded
3-prong wall outlet.

CAUTION: Never connect
or disconnect line cords
while the radio module is
plugged into the wall outlet.
