Some people on this forum have to understand one thing:
1) Read a manual. It could be downloaded from Manufactures Web site.
2) Use Manufactures Web site search engine under support to find a solution to most of the issues before posting a question.
3) You don’t understand something and you need urgent help – call support.
4) You have time to spare – post your problem here and wait for reply.
Sometimes it will take a while for some people to understand to what is going on an especially if you use your product for a first time.
P.S. To Teodor: I don’t take is personally, but please do not give advices, to someone you don’t know personally 🙂 Also some of the users would be much happier not knowing what the diagnostic mode is.
