Acknowledgement

In 1963, Dr. Robert H.Weitbrecht, an
American physicist who was deaf, devel­oped an acoustic coupler that could
send and receive teletypewriter signals
over the telephone lines. His invention,
the Weitbrecht Modem, enabled people
who are deaf to use the telephone for
the first time.

While modern technology now makes it
possible to build advanced microcom­puter devices like your new Ultratec
text telephone, the Weitbrecht modem
remains the major technological break­through that began telecommunications for the deaf. Ultratec wishes
to acknowledge the importance of Dr.Weitbrecht’s contribution to
the welfare of people who are deaf the world over.

Dr. Robert H. Weitbrecht,
1920-1983, inventor of the
first text telephone modem.

Important safety instructions

When using your Supercom 4400, basic safety precautions should
always be followed to reduce the risk of fire, electric shock, and
injury to persons.

Save these instructions!

1. Read and understand all instructions.

2. Follow all warnings and instructions on the Supercom 4400.

3. Unplug the Supercom 4400 from the wall outlet before

cleaning. Do not use liquid or aerosol cleaners. Use a damp
cloth for cleaning.

4. Do not use the Supercom 4400 near water, for example, near a

bath tub, wash bowl, kitchen sink, laundry tub, in a wet
basement, or near a swimming pool.

5. Do not place the Supercom 4400 on an unstable cart, stand, or

table. The Supercom 4400 may fall, causing serious damage to
the Supercom 4400.

6. The Supercom 4400 should be operated only from the type of

power source indicated on the marking label. If you are not
sure of the type of power supply to your home, consult your
dealer or local power company.

7. Do not allow anything to rest on the power cord. Do not locate

the Supercom 4400 where people can walk on the cord.

8. Do not overload wall outlets and extension cords. This

overloading can result in a fire or electric shock.

9. To reduce the risk of electric shock, do not disassemble the

Supercom 4400, but take it to a qualified service person when
service or repair work is required. Opening or removing covers
may expose you to dangerous voltages or other risks. Incorrect
re-assembly can cause electric shock when the Supercom 4400
is subsequently used.

10. Avoid using a telephone (other than a cordless type) during an

electrical storm. There is a remote risk of electric shock from
lightning.

4 • IMPORTANT SAFETY INSTRUCTIONS

11. Unplug the Supercom 4400 from the wall outlet and refer

servicing to qualified service personnel under the following
conditions:

a. When the power supply cord or plug is damaged or

frayed.

b. If liquid has been spilled into the Supercom 4400.
c. If the Supercom 4400 has been exposed to rain or water.
d. If the Supercom 4400 does not operate normally by

following the operating instructions. Adjust only those
controls that are covered by the operating instructions.
Improper adjustment of other controls may result in
damage and will often require extensive work by a
qualified technician to restore the Supercom 4400 to
normal operation.

e. If the Supercom 4400 has been dropped and/or damaged.
f. If the Supercom 4400 exhibits a distinct change in

performance.

12. Do not use the Supercom 4400 to report a gas leak in the

vicinity of the leak.

13. Ultratec recommends plugging your Supercom 4400 into a

surge-protected outlet. This will protect the TTY from
damage caused by electrical surges due to lightning or other
causes.

Battery safety

Caution: To reduce the risk of fire or injury to persons, read and
follow these instructions:

1. Use only the type and size battery specified in the battery

instructions for your unit.

2. Do not dispose of the batteries in a fire. Cells may explode.

Check local codes for possible special disposal instructions.

3. Do not open or mutilate the batteries. Released electrolyte is

corrosive and may cause damage to the eyes or skin. It may be
toxic if swallowed.

4. Exercise care in handling batteries in order not to short them

with conducting materials such as rings, bracelets, and keys.
The battery or conductor may overheat and cause burns.

INTRODUCTION

Welcome to the Supercom 4400™TTY from Ultratec. Your new
TTY has the following special features:

A ring flasher that tells you that someone is calling.

Turbo Code

®

communication protocol. This feature transmits
signals to other Turbo Code TTYs as fast as you type. Turbo Code
also lets you interrupt the other person’s typing.

E-Turbo

™

simplifies calling through relay services that support E-

Turbo, letting you directly dial the person you want to call.

A relay voice announcer that sends a voice message saying,
“Please use text telephone or dial relay,” followed by the number of
your relay service.

Other features that make calling quick and easy are:

• Auto-answer answers calls while you are gone and plays back

messages when you return or when you call from another TTY.

• Call progress displays ringing or busy status of the telephone

line.

• Keyboard dialing from the keyboard or memory, and

redialing of the last number called.

• Relay Dial automatically dials your relay service.

• Call transfer, conference calling, and credit card calling.

• 32k memory—enough to save hundreds of memos and

telephone numbers.

• An extra telephone jack for a signaler or telephone.

• Sticky keys, a feature that allows typing with only one finger

if necessary.

• Auto ID

™

alerts people that you are calling by TTY.

Please note that in this manual TTY, TDD, and text telephone all
refer to the same device.

8 • INTRODUCTION

All you need to do to set up the Supercom 4400 is plug it in! You
have to plug in the AC adapter for 24 hours to charge the batteries.
The ring flasher will not work properly until the batteries are fully
charged. After that, leave the AC adapter plugged in all the time
unless you need to use the batteries during a power outage or while
traveling.

The best way to use the Supercom 4400 is to plug in a telephone
line. This is called direct connect. But if you cannot plug in a
telephone line, you can also make or answer calls by putting a
telephone handset in the Supercom 4400 acoustic cups.

SETUP

Plugging in power and a telephone line

Be sure to pull the plastic tab out of the battery compartment on
the bottom of the Supercom 4400 before you plug in the AC
adapter.

Caution! Do not plug the Supercom 4400 into any line other than a
standard analog telephone line. If you do, you may damage your
telephone system or Supercom 4400, and you will void your

10 • SETUP

warranty.

The picture above shows how to set up for direct connect use. Direct
connect means that the telephone line is plugged directly into the
Supercom 4400. You do not need a telephone. When you use direct
connect, you can dial directly from the keyboard and use auto­answer.

Plug the AC
adapter into an
electrical outlet.

Plug the AC adapter
cord into the jack on
the back of the
Supercom 4400.

Plug one end of
the telephone line
into either tele­phone jack on the
Supercom 4400.

Plug the other end
of the tele-phone
line into a
telephone wall
outlet.

You can also connect by putting a telephone handset in the acoustic
cups if for some reason you cannot plug a telephone line into the
Supercom 4400. See Acoustic calling and answering on page 22 for
more information.

Charging the batteries

The AC adapter supplies electricity to the Supercom 4400 and
charges the batteries. Leaving the AC adapter plugged in will not
harm the Supercom 4400 or the batteries.

Leave the AC adapter plugged in for 24 hours to charge the batteries
when you set up your Supercom 4400. You can use the Supercom
4400 at the same time. Fully-charged batteries will last 45 to 60
minutes. For more information on using battery power, see About the
batteries on page 72.

What kind of telephone line?

When the telephone line is directly connected to the Supercom
4400, you need a standard (analog) home telephone line with either
pulse or tone dialing. If you plan to use the Supercom 4400 in an
office, the line may need modification because many offices have
digital telephone systems. Contact your telephone installer to insure
your line supports a standard single-line telephone. This is the same
kind of line you need for many fax machines or computer modems.

Setting pulse or tone dialing

Your Supercom 4400 comes set for tone dialing, which is used by
most telephone lines. If your line uses pulse dialing, make sure the
Supercom 4400 is set to use pulse dialing. For more information, see
Setting pulse dialing on page 63.

Connecting a signaler or telephone

The Supercom 4400 has an extra jack for a telephone or a signaler.
You can use either jack for the telephone line.

About the control key

The control key ( ) gives instructions to
the Supercom 4400 when you hold it down
and press a function key. Most of the
function keys are on the top row of the
Supercom 4400. See Supercom 4400 function
keys on pages 14–16 for a complete list.

You must hold down the key and then
press the other key. For example, to dial you
must hold down the key while you
press the key.

When you use a function, you can use the escape key ( ) to quit
whatever you are doing and save changes.

About Auto ID

™

The Auto ID feature alerts a hearing person that you are calling
from a TTY. It alerts the person by sending several audible tones
over the telephone line every few seconds. Auto ID helps emergency
services such as 911 detect that you are calling by TTY.

Auto ID comes on when you turn on your Supercom 4400 and
continues until you start a conversation. If you are on-line, you will
see SENDING AUTO ID on the display every time the Supercom
4400 sends out tones.

Auto ID will also begin sending characters whenever no one types
for a few minutes during a conversation. It will continue until
someone starts typing.

Auto ID is not the same as Caller ID, which is a separate service available
through your telephone service provider.

Dialing tips

You may need to type a 9 or other number to reach an outside line if
you are using the Supercom 4400 in an office. The exact method of
dialing will depend on your local telephone system. Dialing a TTY
call should be the same as dialing a voice call.

Use a comma to put in a one-second pause. For example:
9,222 5555.

For long distance, include a 1 and the area code.

Use a ! for a hook flash. A hook flash is used in a voice mail system

Using Turbo Code

®

About Turbo Code

Turbo Code is an enhanced TTY protocol. It sends signals to other
Turbo Code TTYs as fast as you type and allows you to interrupt the
other person at any time during a conversation. The Supercom 4400
takes care of connecting in Turbo Code or Baudot code, depending
on which code the other TTY is using. It only uses Turbo Code
when you connect with another Turbo Code TTY. You can also
“lock” Turbo Code to be always on during a call. See Tubro Code lock
on page 81.

Turbo Code also allows you to use the special “shift” characters on
the top row of your TTY (example: @ # % ^ & * _ < >). If your
call is connected in Baudot, these characters cannot be received or
printed at the other end of the line. This is yet another example of
why Turbo Code is better for TTY communication than Baudot—
especially in the day of sharing your email address.

You know you are connected in Turbo Code if a dot appears in the
lower left-hand corner of the display.

CALLING • 23

This is how the Turbo Code dot looks on the display.

You can switch to Baudot code at any time by pressing

Turbo Code or Baudot code when you turn it off.

Turbo Code interrupt +

Using Turbo Code interrupt

You can interrupt the other person when he or she is typing by
following these steps:

1. Be sure you see the Turbo Code dot in the lower left corner of

your display.

2. Press the interrupt key ( + ) while the other person

is typing.You will see INTERRUPT REQUESTED on the
display.

3. The other person will see “Interrupt” on the display. He or she

can choose to stop typing and let you go ahead or ignore your
interruption and continue.

If you see INTERRUPT on your display while the ring flasher
flashes, it means that the other person wants to interrupt you and
start typing. You can choose to stop and let the other person go
ahead or continue typing yourself. You may also see INTERRUPT
on your display without being connected in Turbo Code if the other
person taps the spacebar a few times.

Turning off Turbo Code interrupt +

You can turn off interrupt so that the other person cannot send an
interrupt to you. Turning off interrupt does not affect outgoing
interrupts. You can still send an interrupt to the other person.
Follow these steps to turn off interrupt:

1. Press the options key (hold down the key and press the

key). You will see PRINT (UP/LOW) CASE on the display.

2. Press the key until you see INTERRUPT (ON) on the

display.
