Teletypewriter (TTY) mode

TTY mode allows people who have hearing or speech impediments to communicate by telephone. HTC Desire 530 is compatible with select TTY phones. HTC Desire 530 and the TTY phone connect using a special cable that may come with the TTY phone. Contact your TTY phone manufacturer to see if the phone supports digital wireless transmission or to purchase the connector cable if one was not provided with the TTY phone.

Turning TTY mode on

  1. Connect the TTY phone cable plug to the HTC Desire 530 headset jack.
  2. From the Home screen, tap All apps button, and then tap Settings > Call.
  3. Tap CDMA call settings > TTY mode, and select TTY Full.
Note: When turned on, TTY mode may impair the audio quality of non-TTY phones connected to the headset jack.
