TTY and TDD Technology  

TTY technology gives the deaf and hard of hearing a text-based system for communicating over phone lines among themselves or with hearing individuals.  Starting in the 1960s, hearing-impaired telephones that used this technology made the deaf and hearing impaired less isolated.  Whether you call them TTYs (Text Telephone), TDDs (Telecommunication Devise for the Deaf), Textphones or Minicoms, these devices now have four million U.S. users.

To use a TTY, you set a telephone handset onto special acoustic cups built into the TTY (some TTY models can be plugged directly into a telephone line). Then, type the message you want to send on the TTY's keyboard. As you type, the message is sent over the phone line, just like your voice would be sent over the phone line if you talked. You can read the other person's response on the TTY's text display.  Each end of a TTY call must have a TTY device.

Henry County 911 provides equal access to citizens using TTY devices for communications to 911.  The 911 center is equipped to receive TTY messages from users of these devices.  Here are a few examples of messages the 911 dispatchers would send when communicating with TTY users:
