[What else should the Administration do once the frequency is recorded?] [The recording in the Master Register does not mean an end of activities of the notifying administration in respect to the concerned frequency assignment. The notifying administration should remain in close cooperation with the licensing authority and any change in the characteristics of the concerned assignment has to be notified to the BR, so as to reflect them in the Master Register, if necessary after additional coordination with the administrations of countries concerned. Furthermore, notifying administrations should remain in close contact with the monitoring authority so as to check whether the concerned frequency assignment is operated in compliance with the notified characteristics and whether other elements (e.g., frequency tolerance) are kept within the limits prescribed by the Radio Regulations. Notifying administrations should also initiate appropriate monitoring programs with a view to detecting any operational or technical irregularities in the operation of frequency assignments from other administrations, and to initiate appropriate actions in this regard, so as to ensure interference-free operation for stations under its jurisdiction.]
