One thing I do to my Moultrie cams is what the rep. told me to do periodacally. Hit thefactory default button to clear the unit's memory and then put in your settings again like you had them before. Be sure to shut unit off, wait 30 secs., then switch back on to boot it up like you do with any computer when a new program is added. Boot it up in between the default and new settings.It has always helped my unit to get back to normal. Hope this helps yours.
