Option on a device fixed in advance of use (6)

I believe the answer is:

preset

(Other definitions for preset that I've seen before include "Adjust beforehand" , "Initially fixed value or control" , "ready to go off when required" , "Initially adjust" , "Determined beforehand" .)

I've seen this clue in The Times.
