I can't read it - did you do a Google or search of the error code to see if you can find it online somewhere?

Do you have the booklet ? maybe it would have the info you need?

loose wires, connections, reset button?, pull out the batteries to reset it???? just guessing on these.

maybe one of the leads has a bad/broken wire ?
