DSI's PhysioTel Digital Implants are thoroughly tested and pertinent results are recorded (see attachment for tested performance parameters).

DSI no longer provides calibration values because they are automatically stored into the implants' memory during testing. When an implant is configured to a CLC, it transmits its calibration values. The calibration data stored in the implant is Cyclic Redundancy Checked (CRCed) to ensure it is correct and not corrupted. This is repeated when data is transmitted to the CLC. If either of these checks fail, it will not be possible for the implant to either join onto a system or be placed into an active mode to start to collect data (since valid calibration data would not be available for the implant).
