Cambridge 302 Gear/Airbrake Warning - How to Test?

Westbender - Thanks for the comments.

Power testing - You don't have to power up/down to test? Hmmm, that
was not my experience - just deploying the airbrakes with gear up
didn't do it, I had to power cycle. Different vintages of 302s?

Documented Tones - I mis-spoke. After a careful review of the 302
manual all the tones are documented in various scattered parts of the
manual - sometimes within the various screen settings and more clearly
in Section 7 "Flying with the Cambridge DDV". This shows that re-
reading the manual following the euphoria of new-avionics-itis is
important.

I would have preferred a concise review of the tones...something like;

Climb Tone -
In Climb mode, lift is indicated by a broken audio
tone.
The tone's pitch and beep rate are proportional to
the climb rate.
Sink Tone -
Sink is indicated by a continuous tone.
The tone's pitch is proportional to the sink rate.
Speed to Fly Tones -
In Cruise mode, short beeps and the UP arrow mean
you should slow down (pull up).
A continuous tone and the DOWN arrow mean you
should speed up (push over).
No tone indicates correct speed to fly.
Minimum Speed Warning Tone -
A di-di-dah “Slow Alarm” tone will be heard if the
glider's airspeed is below the threshold.
Gear/Airbrake Warning Tone (optional) -
A “European Police Car” sound will be heard when;
1) Unlocking the airbrakes when airspeed rises
above 25 knots.
2) During flight with the landing gear retracted
and the airbrakes are unlocked.

The above should include references to the relevant sections of the
manual.

Thanks again, John
