Product: 11C

I just put new batteries in after many years of the calculator being dead.  All I get is vertical lines with a horizontal line at the midpoint, followed by five 8s separated by commas.  Beneath, it reads "User f g begin GRAD D.MY C PRGM"

 

I hit f and g and various buttons but get no change.  Any suggestions?

 

Thanks
