When I flew the MD83 one of our setup procedures was to advance the thrust levers prior to engine start and test the CAWS (Central Aural Warning System). If it worked properly, we would hear a "BEEP BEEP FLAPS, BEEP BEEP SLATS, etc". At the time, I thought of it as a rather rudimentary test procedure but I can't help but think it may have broken the chain here.
