Ok on the 7290 when you hold

and type LGLG it shows the Event Log screen.. Can I clear this whole log or are there some files that I might need to keep?
Also when you click the thumb wheel click options it takes you to Event Logger Options.. and the first line is Mini Log Level.. you can change the option from Warning, Information, and Debug Info, is there a certian one/option this should be set on or does it matter at all?
