ISDT ATR-42

Hi guys, I just got ISDT' ATR-42, fantastic plane (as well as their 72) didn't actually expect to come with a panel and a sound pack. But there is something I don't get: How to turn on the landing lights and taxi lights, and how can I set the heading and course like...+1 incremental, I can only set them every ten degrees (say I'm at HDG 120, one click=HDG 130, same with course). Thanks a lot, happy landings!
