Claim:
A method implemented in a radio base station that performs one or more radio communication functions and includes a human-readable, semi-persistent overlay fixed to a surface of the radio base station, comprising: storing in nonvolatile memory of the radio base station a current operational state associated with the radio base station, the current operational state including a first radio base station configuration; indicating at least with text characters or symbols on the human-readable, semi-persistent overlay the current state associated with the radio base station; changing the current operational state of the radio base station, the changed operational state including a second radio base station configuration different from the first radio base station configuration; updating the text characters or symbols on the human-readable, semi-persistent overlay to reflect the changed operational state associated with the radio base station; and maintaining the indication of the changed operational state on the human-readable, semi-persistent overlay, which is human-readable even if the radio base station is powered-down.
