Recent modifications to the operating procedures for the telescope will be included in the ``INT\?NEWS'' sheet and filed with the control-room copy of this manual. Known faults and warnings, especially those affecting safety, are included in the ``INT\?BEWARE'' list, which should also be filed with this manual in the control room.
Any departures from the normal operating procedures for the telescope (because of faults, temporary repairs or testing) should be included in the current ``INT\?BEWARE LIST'', which must always be consulted before proceeding further.
