A week ago I bought a new HP12C. Everything is working fine except SST-function in RUN-Mode. When the SST-button is holded down the program line should be shown, and on release of the button this line should be excecuted. But when I press down the button the line is not shown and the instruction is excecuted even before releasing the button.
Does anybody had this problem before? Can I resolve this problem by my own or do have to send the calculator for repair?
Thanks in advance for Your help.
Thomas.
