Do you have anything on the stack? The DUP function duplicates the top element of the stack. If the stack is empty then you'll get this error because the calculator can't duplicate nothing.

Hello,
I suppose you can have them repaired, but I suggest you purchase an HP49G+ or an HP50g. I own a 48g and just bought a second hand HP49G+. It is something else: larger screen, 75Mhz processor, about 1.5Mb RAM, an SD card slot (up to 2Gb), RPN, algebraic, and CAS modes, USB and IrDA connectivity, etc.You can even make them work as a 48gx with software from HP web site.
Note that repairing two discontinued models, with the possible scarcity of parts, may prove expensive.
If you are using the TDS software it may be in the backsight menu - try changing your angle to angle right- if not already set up that way - should work
