I just bought a building with a Schindler 2 stop 330A unit, car # A1305-01. I am trying to figure out why the interior lights are turned off. Additionally, I have had multiple service companies come and bid on service, but non-Schindler guys have stated that I need the software so they can service. Schindler is not being very helpful here as they want exclusive and over-priced service contract. Anyone have ideas on this? Thanks.
