What is a method for performing a hard reset on TACAN?

Performing a hard reset on a Tactical Air Navigation (TACAN) system generally involves a complete disconnection of power to the system, which is precisely what shutting down the system entirely entails. This method effectively clears any temporary configurations or errors that may have affected the system's functionality. Once the system is powered down completely and then restarted, it initializes fresh settings, which can resolve unexpected issues.

Other methods, such as adjusting the signal channel, using the touchscreen to turn the channel off, or reconnecting cables, typically do not provide the same level of reset as completely shutting down the system does. These alternatives might only alter specific parameters or settings without fully refreshing the system's operational state. Hence, for a true hard reset, a complete system shutdown is the most effective approach.
