Texas Instruments provides free out of warranty repair for connector (link port) problems on graphing calculator and data collection devices that are up to three years old, if it is determined that the link port is broken. To receive a replacement, contact TI (1-800-TI-CARES) to make arrangements for the free replacement of the unit. Please note that the original unit will not be returned but will be replaced with a reconditioned unit.

If the link port is broken the likely symptom will be a “link transmission error” when trying to transfer programs or data. The physical symptoms of a broken link port are that the link cable will fit loosely into the link port and/or the plastic around the link port is missing or broken.
