TTY Operation
You can use an optional TTY device with your
phone to send and receive calls. You must plug the
TTY device into the phone's headset jack and set
the phone to operate in one of three TTY modes.
Notes:
• Use a TSB-121 compliant cable (provided by the
TTY manufacturer) to connect the TTY device to
your phone.
• For optimal performance, your phone should be at
least 12 inches (30 centimeters) away from the TTY
device. Placing the phone too close to the TTY device
may cause high error rates.
Set TTY Mode
When you set your phone to a TTY mode, it operates in
that mode whenever the TTY device is connected.
