2. Dial the phone number of the person you are trying to reach who
also has a TTY device connected to their phone. If the prompt
displays asking if you want to turn on the phone, tap Yes.

TTY
keyboard.
The letters typed into the machine are turned into electrical signals
that travel over regular telephone lines. When the signals reach
their destination (another TTY device), they are converted back into
letters which appear on a display screen, are printed out on paper,
or both.
When you are finished typing your phone conversation, the person
on the other end of the line may begin typing their answers or
comments to you.

TTY mode is enabled AND a plug has been inserted into the
headphone jack, TTY audio mode will be activated and voice
quality will decrease.
