I have a Fellowes DS-1200Cs Shredder. The yellow "safesense' light is on and the shredder will not run. The shredder is about 15 months old (warranty is 1 year) and probably has a total of 3 hours of run tine over that 15 months -- NOT all at the same time. Is there a way to bypass the safesense feature to see if the shredder will work without it? I'm retired and NO small children live in my house - my grandsons are 17 and 18! Thanks for any help!
