•
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 errorrates.
