Second Functions 0 (Second Function)-Enables you to perform the "second" functions that are marked over some of the keys. To perform a second function, press 0 and then the appropriate function key. When you press 0, 2nd appears in the display until you press another key. If you press 0 and then a key that does not have a second function, the key performs its normal function. If you accidentally press 0, press it again to cancel its effect.

Pressing u also sets the calculator to floating-decimal format and financial mode. - (Clear Entry/Clear)-Clears incorrect entries, error conditions, the display, or pending operations. It does not affect the memory, the mode registers, or the display format. 0 b (Clear Mode Registers)-Clears any values that have been stored in the mode registers. Note: Changing to a new mode also clears the contents of the mode registers. 3
