Comment sem4160 SNF 2011-05-10 11:56:43: Only flash tip once

While the tool is coming back to normal, only flash the tip once at the  beginning of your session. If you flash again you will be starting from   scratch. Just hit the on button again and it will restore extractiion. Field service says the resolution improves over time so be patient and           please make comments regarding your session.
