How do I repair my calculator?
The only repairs that can be done is the replacement of the batteries. Any other repairs will be simply too expensive considering these are hand units. At one time I made a good living repairing calculators but as the replacement cost went through the floor so did my job out the door.

I cant find the factorial
To find the factorial command, go to the Run screen and press [OPTN] [F4] (PROB) [F1] (x!). For example, to find 5!, press 5 [OPTN] [F4] [F1] [EXE].
