TTY operation
You can use an optional teletypewriter (TTY) device
with your phone to send and receive calls. You must
plug the TTY device into the phone's headset
connector and set the phone to operate in one of
three TTY modes.
Notes:
• 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
2.5mm 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.
