My new 995 worked fine for the last couple days then all the sudden today I keep seeing self cal3 and self cal7 pop up. Once it wouldnt stop so i turned it off then back on and it worked fine for a couple minutes then started again then stopped on its own. Should I return and exchange it tomorrow? I also got the 4 year warranty on it and its from an authorised dealer. They should just swap it with another new one for me. How often does the 995 get this problem?
