The Gull Rock Log Safe

The tide log for Gull Rock Lighthouse is locked in a brass safe. The keeper has gone ashore, and a fog is rolling in — the relief keeper needs the log tonight. The keeper tested the lock each Sunday and wrote every try in a notebook, with the answers the safe gave. No symbol repeats in the code. Work out the four-symbol code.
