I am not an expert but suggest either a review of handbook topics, or perhaps someone will help you troubleshoot from this list.  You might also do a search on line for topics.  Personally , I have had a KPA500 and 1500 and don't have the issue.  However, each of us has a different setup. I don't think you have to have thick skin or think you aren't in a club here.  There are a few who hover over us.  Be patient and get the info you need to fix the issue.
