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.
Note:
Use a TSB-121 compliant cable
(provided by the TTY manufacturer) to
connect the TTY device to your phone.
Note:
Set the phone to level 4 (middle setting)
for proper operation. If you experience a high
number of incorrect characters, adjust the
volume as needed to minimize the error rate.
Note:
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.
