Before Starting Calculations If after making corrections, input of the formula is To clear memory contents, press [0] [STO] [M]. Addition/subtraction to or from sum in memory cannot be carried out with [M+], [SHIFT] [M–] keys in "SD" mode and "REG" mode. Difference between [STO][M] and [M+], [SHIFT][M–] : Both [STO] [M] and [M+], [SHIFT] [M–] can be used to input results into memory, however when the [STO] [M] operation is used, previous memory contents are cleared. When either [M+] or [SHIFT] [M–] is used, value is added or subtracted to or from present sum in memory. Example: Input 456 into memory "M" using [STO] [M] procedure. Memory already contains value of 123. Operation Modes complete, the answer can be obtained by pressing [ = ]. If, however, more is to be added to the formula, advance the When using this calculator, it is necessary to select the cursor using the [4] key to the end of the formula for proper mode to meet your requirements. This can be done input. by pressing [MODE] to scroll through sub-menus. Then select the appropriate mode by keying in the number.
