Clearing the Calculator


The calculator contains several keys used for clearing. When you use one of the clear keys on the calculator, you should be sure that you will not affect other areas you do not wish to clear.



The [ CLEAR ] Key

When you press the [ CLEAR ] key, the alphanumeric area of the display is cleared. The standard display format is returned. Also, any fields in progress and any pending operations in the AOS stack are cleared.

The [ CE ] Key

When you press the [ CE ] key, the entry you have just made is cleared if no other function keys have been pressed. The AOS stack is not affected. This enables you to continue with a calculation without starting over.

The [ 2nd ] [ CMS ] Key Sequence

When you press [ 2nd ] [ CMS ], the data registers, as defined by the current partition, are cleared.

The [ 2nd ] [ CP ] Key Sequence

When you press [ 2nd ] [ CP ] in the learn mode, programs you have stored in program memory are cleared.

The [ 2nd ] [ F:CLR ] Key Sequence

When you press [ 2nd ] [ F:CLR ], the function key-label area of the display is cleared.

The RESET button


You should only press the RESET button as a "last resort" to restart your calculator when a problem occurs that prevents you from entering from the keyboard (Note: in RPD-95, you should not need the RESET button). When youpress the RESET button, the display is cleared and replaced with the message MEM MAY BE LOST. The following conditions are changed. For other effects, refer to "System Parameter Settings" in Appendix A.
  • The display format is changed to standard notation.
  • The decimal point is changed to floating decimal.
  • The number base is changed to decimal.
  • The temporary register is cleared.
