CLC Name: Select the Set CLC Name... button to create or change the name of the CLC. This name is saved on the CLC and will be the name seen when searching the network for available CLCs to add to the configuration with the PhysioTel Digital Configuration. B. About: Important information including CLC model and serial numbers, current frequency, IP Address, and Firmware. This same information is available by hovering the mouse cursor over the line item in the List View. C. Frequency Dropdown box used to select the frequency of the CLC. D. Enable TRX(s) Checkbox used to enable (checked) and disable (unchecked) the CLC broadcast frequency. Disabling the TRXs may be useful in preventing the CLC from interfering with the implant configuration process of another CLC in the configuration or on the network. E. Configured Implants Lists the implants currently configured to this CLC. F. Search for Implants... Allows the user to search for implants that are powered ON and in range for assignment to the CLC within this configuration. G. Remove Implants Allows the user to select the implants from the Configured Implants list and remove them from the configuration. H. TRXs: List of TRXs and serial numbers assigned to that CLC and the “Jack” number on the back panel of the CLC the TRX is plugged into.

Information Provides the user with instructions on actions to perform on that Details page. Implant Details The Implant Details can be accessed by left-clicking on any of the implant names in the List View. The Implant Details view contains implant information, as well as some important interactive features. Implant Details contains the following information: Page 118 DSI Implantable Telemetry • Publication 012527-001 REV 03 • www.datasci.com ©2026 Data Sciences International Implant Details Field Description A. Implant Name: User may rename the implant by selecting the Set Implant Name... button. In the displayed dialog, enter the desired name in the text field and select OK. Upon selecting OK, a will display next to the existing implant name while the CLC communicates the name to the Implant. Once the implant is programmed with the name, the dialog will close. The name specified here is also used by Ponemah as the Subject Name when automatically creating the Subject upon clicking Save & Exit within this dialog. B. Enabled: This check box will toggle the implant between ‘Enabled’ and ‘Disabled’ modes. The Enabled mode allows the software system to record, store, and analyze data from the implant. WARNING: if the implant is not Enabled, the implant will still be powered ON and in communication with the system, but no data from the implant will be acquired. C. About: Important information including model and serial numbers, activation and manufacture dates, as well as a battery level indicator. This same information is available by hovering the mouse cursor over the line item in the List View.
