I was informed (and verified) that there is a way to easily test the
302 warning system while on the ground.

- Power down the 302
- Unlock the airbrakes with the gear unlocked/up
- Power up the 302

The alarm will then sound (euro siren) after the self test is
complete. *A large upwards pointing arrow will appear in the display,
different than the small speed up/down arrows, meaning I suppose that
your gear is up. *You can silence the alarm by pushing the button.

Yet another undocumented feature/sound from the Cambridge 302!

You don't have to power it down. Simply unlocking the brakes/spoilers
with the gear up will produce an alarm. You can turn the alarm on and
off by locking/unlocking the brakes/spoilers with the gear up.
Powering up/down does nothing different. That does not test the speed
enabled (spoilers unlocked on takeoff) alarm however.

By the way, with the 303, you'll get an appropriate text message on
the screen depending on which alarm it is.
