What Is TTY Mode on Your Phone; How It Work

 Many phone users are ignorant of the TTY mode on their phones and those who had come across it don’t know how it works.

It is a Teletypewriter which is also known as a Text Telephone (TDD). This function on your phone allows people with hearing impediments people who are deaf or those with speech or language disabilities to communicate via the telephone.

The teletypewriter mode when put on, allows your phone to connect to a compatible teletypewriter device through the use of special cords or cables that you attach to your phone via the phone’s headset jack.

A teletypewriter is a device with a small display screen that translates audio signals into words and displays them for the person to see.

 

The device can then re-encode typed replies into audio for the other party to be able to hear. However, depending on the model of the device It may or may not print out the message.

 

Your phone must be compatible with selected Teletypewriter devices and also ensure that the right connecting cables are used.

 

Please also check with the manufacturer of your TTY device to ensure that the device supports digital wireless transmission.
