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.

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

the Miniprint 425, 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 Miniprint 425 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.

IMPORTANT SAFETY INSTRUCTIONS • 3

11.Unplug the Miniprint 425 from the wall outlet and refer

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.
