A ship has arrived at a pilot station in UK waters and the pilot has arrived on the bridge. What action should the master now take?

The master should: (1) have the "H" flag or night signal shown; (2) introduce himself as master; (3) conduct a master/pilot information exchange as recommended in IMO Resolution A. 960(23); and (4) ensure that the OOW will monitor the ship's progress whilst under pilotage.
