My 15c is in complex mode and I don't recall how to get it back to regular mode. Can someone help?

It did not remove it. Not sure if I understand the instructions. Thanks for your help.

It can't fail ! :-O

With the calculator turned on, you must press exactly
these keys:

     [g]   (the blue key)

     [5]   (the 5 key, which has CF printed in blue)

     [8]   (the 8 key)

The complex mode annunciator "C" in the display should
disappear and your HP-15C will be out of complex mode. Else there's some keyboard or hardware problem.

Best regards from V.
