Notes:
• Use a TSB-121 compliant cable (provided by the TTY
manufacturer) to connect the TTY device to your
phone.
• Set the phone volume to level 4 (middle setting) for
proper operation. If you experience a high number of
incorrect characters, adjust the volume as necessary
to minimize the error rate.
• 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.
Setting TTY Mode
When you set your phone to a TTY mode, it operates in
that mode whenever the TTY device is connected.
