cable connections
Your phone has a
mini-USB port so
you can connect it to a
computer.
If you use a USB cable
connection:
• Make sure to connect the phone to a
high-power USB port on your computer (not a
low-power one such as the USB port on your
keyboard or bus-powered USB hub). Typically,
USB high-power ports are located directly on
your computer.
Note: If you connect your phone to a
low-power USB port, the computer may not
recognize your phone.
• Make sure both your phone and the computer
are turned on.
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 connector 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.
