Note
A TTY is a communication device used by people who are hard of
hearing or have a speech impairment. TTY does not work from mobile
phone to mobile phone. Use a TSB-121 compliant cable (provided
by the TTY manufacturer) to connect the TTY device to your phone.
Your phone has a 3.5 mm jack. Set the phone to Medium volume level
for proper operation. If you experience a high number of incorrect
characters, adjust the volume as needed to minimize the error rate.
For optimal performance, your phone should be at least 12 inches (30
centimeters) from the TTY device. Placing the phone too close to the
TTY device may cause high error rates.
