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.

All you need to do to set up the Miniprint 425 is plug it in!
You must 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 the batteries are charged,
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 Miniprint 425 is to plug in a
telephone line.This is called direct connect. But if you cannot
use direct connect, you can also make and answer calls by
putting a telephone handset in the Miniprint 425 acoustic
cups.

SETUP

Plugging in power and the telephone
line

Be sure to pull the plastic tab out of the battery compartment
on the bottom of the Miniprint 425 before you plug in the AC
adapter.

8 • SETUP

The picture above shows how to set up for direct connect
use. Direct connect means that the telephone line is plugged
directly into the Miniprint 425.You do not need a telephone.
When you use direct connect,you can dial from the keyboard
and use auto-answer.

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 Miniprint 425. See Acoustic calling and
answering on page 17 for more information.

Plug the AC
adapter into an
electrical outlet.

Plug the AC adapter
cord into the jack on
the back of the
Miniprint 425

Plug one end of
the telephone line
into either
telephone jack on
the Miniprint 425.

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

Charging the batteries

The AC adapter supplies electricity to the Miniprint 425 and
charges the built-in batteries.Leaving the AC adapter plugged
in will not harm the Miniprint 425 or the batteries.

The first time you set up your Miniprint 425, leave the AC
adapter plugged in for 24 hours to charge the batteries.You
can use the Miniprint 425 at the same time. Fully-charged
batteries will provide 45 to 60 minutes of normal use. For
more information on using battery power, see About the
batteries on page 31.

What kind of telephone line?

When the telephone line is directly connected to the
Miniprint 425, you need a standard (analog) home telephone
line with either pulse or tone dialing. If you plan to use the
Miniprint 425 in an office, the line may need modification
because many offices have digital telephone systems. Contact
your telephone installer to be sure your line supports a
standard single-line home telephone.This is the same kind of
line you need for many fax machines or computer modems.

Caution! Do not plug the Miniprint 425 into any line other
than a standard telephone line. If you do,you may damage
your telephone system or the Miniprint 425.You will also
void your warranty.

Setting pulse or tone dialing

Your Miniprint 425 comes set for tone dialing,which is used
by most telephone lines. If your telephone line uses pulse
dialing, change the Miniprint 425 setting to pulse dialing.See
Setting pulse/tone dialing on page 26 to change the setting.

Connecting a signaler or telephone

The Miniprint 425 has an extra jack for a telephone or a
signaler.You can use either jack for the telephone line and
telephone or signaler.

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 service centers such as 911
automatically detect that you are calling by TTY.

Auto ID comes on when you turn on your Miniprint 425 and
continues until you start a conversation. If you are on-line,
you will see SENDING AUTO ID every time the Miniprint 425
sends out tones.Auto ID will also begin sending tones when­ever no one types for a few minutes during a conversation. It
will continue until someone starts typing.

You can turn off Auto ID in the options menu.See Turning
off Auto ID on page 27.

Note: When you turn off Auto ID,it stays off and will not
send tones until you turn it on again.This means that an
emergency service center such as 911 cannot use Auto ID
tones to detect your TTY call.

About the printer

The printer is on when you turn on your Miniprint 425 for
the first time. Press the print key ( + ) to turn off the
printer.The display says PRINTER OFF. Press the print key
again to turn the printer back on.You can turn the printer on
or off at any time, including during a call.

The printer starts a new line after 24 characters are typed. If a
word is too long to fit at the end of a line,the printer divides
it with a dash.You can also start a new line yourself by
pressing the key. Often a few characters will not be
printed at the end of a conversation unless you press the

key before you turn off the TTY.

About Turbo Code

®

Turbo Code is an enhanced version of Baudot Code. It sends
signals to other Turbo Code TTYs as fast as you can type.The
Miniprint 425 takes care of connecting in Turbo Code or
Baudot code, depending on which code the other TTY is
using. It only uses Turbo Code with other Turbo Code TTYs.

Turbo Code also allows you to use the special “shift”
characters on the top row of your TTY keyboard (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 when a dot
appears in the lower left-hand corner of the display.

If necessary, you can turn off Turbo Code at any time. If you
do, the Miniprint 425 will not use it. Follow these steps to
turn off Turbo Code:

1. Press the options key ( + ).You will see PRINT

(UP/LOW) CASE on the display.

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

the display.

3. Press the to change the setting to OFF.

4. Press the key to leave options.Turbo Code is now

turned off until you turn it on again.

Note: During a call, you may temporarily turn off Turbo Code
and switch to Baudot (45) code by pressing the key,the

key, and the key all at the same time ( + + ).

Using Turbo Code interrupt

You can interrupt the other person when he or she is typing
by pressing the interrupt key ( + ).Your display says
INTERRUPT REQUESTED.The other person’s TTY display says

18 • CALLING

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

If you see INTERRUPT on your display while you are typing,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.

Interrupt only works with newer TTYs and when the other
person is typing continuously.If the other person does not
stop typing when you press + ,the other TTY probably
does not have the interrupt feature.

You can turn off interrupt so that the other person cannot
send an interrupt to you. See Turning off interrupt on page

27.Turning off interrupt does not affect your outgoing
interrupts—you can still send an interrupt to the other
person.

Wait for response

If the other person tells you to hold and you think it might
take a long time before they come back,use the wait-for­response feature.The Miniprint 425 will flash the ring flasher
when the other person starts typing again. Follow these steps
to turn on wait for response:

1. When you see the other person type HOLD PLEASE or

something similar, hold down the and keys and
press the key ( + + ).The display says WAITING.

2. When you see the ring flasher flashing, the other person is

typing. Continue your conversation.The flashing will stop
when you start typing.

Change to other TTY

If you want to change TTYs in the middle of a conversation,
you can put the call on hold,go to another TTY, and tell the
Miniprint 425 to hang up.You must be using direct connect
to use this feature.Follow these steps to use the change-to­other-TTY feature:

Transferring a call

Office telephone systems vary widely and specifics of how to
transfer a call will be different for each system. Most
telephone systems require a hook flash to transfer a call. On
the Miniprint 425, typing an ! when you are dialing sends a
hook flash. Here is an example of typical steps required to
transfer a call while you are on the line with another person:

1. Press the dial key ( + ).You will see TYPE NAME on

the display.

2. Type an ! (hold down the key and press the key).

3. Type the number of the extension to which you are

transferring the call.

4. Press the key.

5. Turn off your Miniprint 425 to hang up when you see the

last number you dialed appear on the display.

The exact steps you need to follow will depend on your local
telephone system.Transferring a TTY call will require the
same steps as transferring a voice call.

baud rate is set to the auto setting.The auto setting uses
whatever code it needs to answer a call.If you need to
specify the code that the Miniprint 425 uses, you can set the
unit so that it will only use either 45.5-baud or 50-baud
Baudot code.When you do, the Miniprint 425 will not try to
use other codes. Follow these steps to change the Baudot

• 50 to use only 50-baud Baudot code.TTYs purchased in

Australia,New Zealand, and South Africa use 50-baud
Baudot code. Note that in order to use 50-baud Baudot
code, you must change the setting to 50.The Auto

CARE & REPAIR

Replacing the printer paper

The printer uses high-quality thermal paper.Use the order
card that comes with the Miniprint 425 to order paper. If you
do not have a card,contact your dealer or Ultratec (the
Ultratec address is on the inside front cover of this manual).

Turn on the Miniprint 425 and be sure the printer is on, then
follow these steps to put in a new roll of paper:

30 • CARE & REPAIR

Take off the
printer cover by
pushing in on the

Hold the new roll
so that it unrolls
from the bottom.
Feed the end into
the slot in the
back of the
printer.

Press the
key a few times
until the paper
comes out of the
top of the
printer. Pull the
paper up gently.

Return

Feed the paper
through the slot
in the printer
cover.

Put the roll in
the holder
behind the
printer. Replace
the printer cover.

About the batteries

The Miniprint 425 runs on batteries when you unplug the AC
adapter or when the power fails.Fully charged, the 6 AA
rechargeable NiCad batteries will provide 45 to 60 minutes of
normal use.

When the power light blinks,you have about 5 minutes of
battery power left.The batteries will last longer if you turn off
the printer when you use battery power.

Checking the batteries

The batteries lose their ability to hold a full charge if you
keep the Miniprint 425 plugged in all the time. If you want to
be sure the batteries stay fully-charged, check them once a
month. Follow these steps to check the batteries:

1. Unplug the AC adapter.

2. Turn on the Miniprint 425 for 30 minutes.(You can still

use it for calls during this time).

3. If the power light glows steadily after 30 minutes,the

batteries are fine. Plug the AC adapter back in and turn off
the Miniprint 425. If the power light blinks within 30
minutes, exercise the batteries.

Exercising the batteries

1. Leave the Miniprint 425 on with the AC adapter

unplugged until the power light flashes.

2. Plug in the AC adapter for 24 hours. (You can use the

Miniprint 425 for calls during this time).

3. Unplug the AC adapter and leave the Miniprint 425 on for

30 minutes.

4. Repeat steps 1 to 3 until the power light glows steadily

after 30 minutes without the AC adapter.

CARE & REPAIR • 31

Replacing the batteries

Replace the batteries every two or three years, or when they
always run down in less than 30 minutes and exercising them
does not help.To change batteries, turn over the Miniprint
425 and follow these steps:

32 • CARE & REPAIR

Take off the
battery cover by
pushing in on
the latch and
lifting up.

Take out the old
batteries and put
in new ones. Be
sure the

+ and –

ends match the
sumbols on the
holder.

Put the battery
cover back on.

CAUTION!

The rechargeable batteries contain nickel and cadmium.Do not
burn or puncture them. If you do, they could release toxic
material that could injure you. Do not dispose of them in
household trash. For information about recycling or proper
disposal, consult your local trash collection or disposal
organization.

Troubleshooting

Direct connect

Dialing does not work.

An incoming message does not make sense.

If you have a handset in the acoustic cups on the Miniprint
425, press it down firmly.

The telephone connection may be weak or the other TTY is
sending the wrong signals. If you are using Baudot code,press
the sensitivity key (hold down the key and press the
key).The display says HIGH SENSITIVITY. Sensitivity returns
to normal when you press the sensitivity key again or turn off
the Miniprint 425.

Some characters are not being sent.

Because Baudot code does not support special characters, it
does not recognize some of the “shift” characters on the top
row of a TTY (example: @ # $ % ^ & *_<>). To type these
characters (such as in an email address) make sure your call is
connected in Turbo Code (see About Turbo Code
