Skyscan Atomic Clock

I have had this product for about two years. SKYSCAN Atomic Clock.All this while I had a good signal lock and the time was accurate. Then my battery (two AAs) were low so I replaced them with new ones; deligently following instructions specified in the manual. Ever since I keep losing my signal link and the clock runs slow. I moved the clock around just in case there was interference (although it worked fine for the last 2 years) all for nought. I don't have any new appliances that could cause interference that were not in the same location for the last 2 years. What is needed is a manual "force link" button so as to link-up with the radio waves. My Casio watch has this why can't this clock? All in all an OK product but next time I'm going with Oregon Scientific. I am told that their product is more reliable by far. http://astore.amazon.com/ashley-furnitures-20/search/103-6450442-4737435?node=3&keywords=skyscan+atomic+clock&preview=&x=8&y=15
