TTY Mode A TTY (also known as a TDD or Text Telephone) is a telecommunications phone that allows people who are deaf, hard of hearing, or who have speech or language disabilities, to communicate by telephone. Your phone is compatible with select TTY phones. Please check with the manufacturer of your TTY phone to ensure that it is compatible with digital cell phones. Your phone and TTY phone will connect via a special cable that plugs into your phone's headset jack. If this cable was not provided with your TTY phone, contact your TTY phone manufacturer to purchase the connector cable. Turn TTY Mode On or Off 1. Press > > System settings > Call > TTY mode. 2. Tap TTY Off to turn TTY mode off or tap TTY Full, TTY HCO or TTY VCO. To access the state Telecommunications Relay Service (TRS) for assistance with TTY calls: ► Dial to reach an operator. For additional information about Sprint Relay Services and TTY compatibility, call Sprint Relay Customer Service at 800-676-3777 or visit www.sprintrelay.com. Note: In TTY Mode, your phone will display the TTY access icon. When enabled, TTY mode may impair the audio quality of non-TTY phones connected to the headset jack. WARNING: 911 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 911 may be corrupted when received by public safety answering points (PSAPs), rendering some communications unintelligible. The problem encountered appears related to 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. Proximity Sensor You can access the phone's proximity sensor through the Call Settings menu. When receiving and making calls, this sensor automatically turns the backlight off and locks the touch keypad by sensing when the phone is near your ear. This extends battery life and prevents the touch keypad from activating unintentionally during calls. To enable the Proximity Sensor: 1. Press > > System settings > Call. 2. Tap the Proximity Sensor checkbox to enable it. (A blue checkmark will appear.) Settings 151
