Make it easier for people who are deaf, hard of hearing, or speech-impaired to use phones to communicate, by letting them send and receive typed messages. Also known as TTY, TDD, and teletypewriters, these text telephone adapters can be used to contact others, even if they don’t have an adapter. To converse with someone who is not using an adapter, first call the U.S. National Relay Service. They’ll read your message to those who only have a phone and then type their message back to you.

Unlike other text telephone adapters, these don’t need to be plugged into a direct phone line. They run on AC power or rechargeable batteries, so you can move them wherever they’re needed. Their phone holder/receiver is sized to accommodate a variety of phone handsets, including those found on our standard, cordless, outdoor, and hazardous location phones. They are not, however, compatible with mobile phones.

Use these phones to connect with off-site colleagues. They receive and transmit signals simultaneously so calls never sound choppy. Connect them to any standard phone line.
