I have a error code on my PANASONIC WORKIO DP-2000 Photocopier which says Replace battery U90,This error has come on since i un-plugged the machine & left it unplugged for a few weeks, Now the machine will not start up and just displays the Replace Battery U90, Could anyone advise on a solution ?

U-90 error please check if u have pulled out the battery ur self is it installed in correct position, next if u can open its control panel then check on board that are the 2points attaching to battery properly if No then make it in the correct way(points),if Yes then replace new battery the problem will be solved.bye
