TTY (Teletypewriter) Mode
TTY mode allows people who have hearing or speech impediments to communicate by telephone. HTC
One A9 is compatible with select TTY phones. HTC One A9 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.
When establishing your Sprint service, please call Sprint Customer Service using the state
Telecommunications Relay Service (TRS) by first dialing
state TRS with this number: 866-727-4889.
To turn TTY Mode on or off:
1. Tap > >
2. Tap Call.
3. Tap CDMA call settings > TTY mode.
4. Tap TTY Full, TTY HCO, or TTY VCO. Tap TTY Off to turn TTY mode off.
Note: When enabled, TTY mode may impair the audio quality of non-TTY phones connected to the
headset jack.
Warning: 9-1-1 Emergency Calling
Sprint recommends that TTY users make emergency calls by other means, including
Telecommunications Relay Services (TRS), analog cellular, and landline communications. Wireless TTY
calls to 9-1-1 may be corrupted when received by public safety answering points (PSAPs), rendering
some communications unintelligible. The problem encountered appears related to TTY equipment or
software used by PSAPs. This matter has been brought to the attention of the FCC, and the wireless
industry and the PSAP community are currently working to resolve this.
