Tty Operation - Motorola T721 Getting Started Manual

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 3 TTY modes.
For additional information, or if you have questions, please
contact your cellular service provider or Motorola. Motorola
has tested various TTY products manufactured by
Ameriphone and Ultratec.
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.
