Installation Error Messages
Low Battery
Do not attempt to download a Flash application if the low-battery message appears on the home
screen. Low battery indication is shown on the initial screen. If you receive this error during an
installation, change the batteries before trying again.
Invalid Signature or Certificate
Either this device does not have a certificate to run the application, or electrical interference
caused a link to fail. Try to install the application again.
Error in Xmit
This problem is usually associated with the unit-to-unit cable and its connection between the
devices. Make sure the cable is firmly inserted in the link port of each device.
Communication Error
This error indicates that the TI Connect™ software (“Unable to communicate with device”) or
TI-GRAPH LINK™ software (“Link Transmission Error”) is unable to communicate with the
device. The problem is usually associated with the TI-GRAPH LINK cable and its connection to
the device or to the computer.
• Make sure the cable is firmly inserted in the device link port and the computer.
• Verify that the correct cable type is selected in the software link settings.
• Verify that the correct communications port (Com Port) is selected in the software link
settings. (This does not apply if you use the USB port and TI Connect software.)

it on your computer using TI Connect or TI-GRAPH LINK™ software for the TI-83 Plus. You can
reload it to the TI-83 Plus later using TI Connect or TI-GRAPH LINK software.
