Troubleshooting
Direct connect
Dialing does not work.
Make sure you have the right tone or pulse setting for your telephone
system.
The display says NO DIRECT CONNECT.
The Superprint 4425 is not properly connected to the telephone line. Be
sure the cord is firmly plugged into the Superprint 4425 and the
telephone wall jack. You can also try using a different telephone cord or
wall jack.
Poor reception
The display shows all numbers, symbols, or unreadable
characters instead of words.
Press the . If that does not help and you have a Turbo Code
connection, try changing from Turbo Code to Baudot code. Hold down
the and keys and press the key to change to Baudot code.
An incoming message does not make sense.
If you have a handset in the acoustic cups, press it firmly. The telephone
connection may be weak or the other TTY may be 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 when you turn off the Superprint 4425.
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
