The TC-700 had limited physical buttons, but the software allowed you to remap them.

Unlike modern "cloud-based" radio management, the TC-700 software was a relic of an older era: a standalone executable file that demanded a physical connection and a specific sequence of button presses.

Before plugging in the radio, install the cable driver. Check your Device Manager to ensure the cable is assigned a COM port (e.g., COM3) without any yellow "error" icons.

Once the data is read, you will see a spreadsheet-like interface.
