TTY with Large Visual Display is for TTY users who are visually impaired.  The display connects to an external port on the Superprint 4425D-AS (with ASCII) to magnify the characters in your TTY conversation.

• Bold type characters on large display are 10 times larger than a standard TTY
• Built in printer on the Superprint 4425D-AS can be used at the same time the Large Visual Display is being used.
