Cambridge 302 Gear/Airbrake Warning - How to Test?

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!

The power up alarm sounds with brakes unlocked with the gear DOWN and
locked.

After power up test execution the gear warning is as expected - the
gear alarm only sounds if the brakes are unlocked and the gear is not
down locked.

The alarm may also sound on power up with the brakes unlocked and the
gear not down and locked but I can't be sure of that as my assembly
routine has gear down and glider pushed back from trailer before the
batteries are fitted.
