Casio FXCP400 manuals
Computer Equipment > Calculator
When we buy new device such as Casio FXCP400 we often through away most of the documentation but the warranty.
Very often issues with Casio FXCP400 begin only after the warranty period ends and you may want to find how to repair it or just do some service work.
Even oftener it is hard to remember what does each function in Calculator Casio FXCP400 is responsible for and what options to choose for expected result.
Fortunately you can find all manuals for Calculator on our side using links below.

Note that you cannot switch the active window while an operation is being performed in the current active window Resize the active window While a dual window is on the display, tap r. This causes the active window to so it fills the display fill the display. To return to the dual window display, tap ragain Swap the upper and While a dual window is on the display, tap S. This causes the upper window lower windows to become the lower window, and vice versa. Swapping windows does not have any effect on their active status. If the upper window is active when you tap S for example, that window will remain active after it becomes the lower window Close the active windows While a dual window is on the display, tap C at the top right corner of the fill the display uChanging the Display Orientation (Main Application Only) Using the OMenu The following describes all of the items that appear on the Omenu 1 Tapping [Variable Manager] starts up Variable Manager.
