You can find CADI on the net if you look hard enough
But some of the later software versions you need the SPECI tool or whatever app it is they run on their iphones now

Tell the customer that if Schindler turn up offering a free software upgrade to not let them in the door!! it will lock you out of essential parameters and you will not be able to access them with out the tool..

Or you can but the modu-tool that basically runs CADI and the OTIS and ORONA emulators all in one and you can reset the counters on pre 2008 KONE LCE with an adaptor

Whats the Thyssen PDA ?? is it the POME tool??
