How to on ground check the gear and stall horns

[Hank]

I used to have a car with different pitch sounds for seatbelt, headlights on and keys in the ignition. Much nicer than one horn for everything . . . .

The only way I know of to test the gear horn is in flight, with your gear up, go to low rpm and it should sound. Tested also as part of my slow flight and stall practice.
