The constant is performed automatically by the "=" key, "%" key, or "%" key without a constant for addition, subtraction and division while the first operand is the constant for multiplication. 4.1.2 Number Entry Numerals can be entered up to 12 digits. 4.1.3 Memory Protection In any error detection, the memory contents present before the error detection are protected. 4.1.4 Memory Indication If the memory contents are numbers other than zero, "M" is indicated in the sign-digit position. 4.1.5 Auto Power Off If no key is pressed for a specific period of time, the power supply will be automatically turned off (pin option). This time interval up to power-off is approximately 8 minutes. 4.2 Keyboard Description Equal Key (=) Performs the keyed-in operation and maintains that operation for possible use Establishes power/reciprocation calculation Multiplication Key (× ×) Pressing this key enters the multiplicand Performs the previous operation and displays the result Division Key (÷) Pressing this key enters the dividend Performs the previous operation and displays the result Product Specification (V1.0) 04.02.2010 (This specification is subject to change without further notice) •3 EM34014A 10/12-Digit Calculator Battery/Solar/Dual Power Type Addition Key (+) Pressing this key conditions the IC for an addition operation Performs the previous operation and displays the result Subtraction Key (− −) Pressing this key conditions the IC for a subtraction operation Performs the previous operation and displays the result Percent Key ( %) The purpose of the percent key is to allow for calculation of add-on and discount. Determination of add-on requires the principal amount to be the first entry followed by the "+" or "×" key, with the percentage being the second entry. Pressing the percent key yields the amount to add on, such as TAX or interest. Pressing the "=" key adds this amount to the principal. Change Sign Key (+/-) Pressing the "+/-" key twice in succession causes the corresponding sign to appear and disappear. During a digital entry, this function changes the sign of the entered factor. Clear Key and Power-on Key (C & On) Pressing the power-on key the first time displays the number "0". In the middle of a digital entry, pressing this key the second time will clear all the operating registers. Clear Entry/Clear Key (CE/C/On) During a digital entry, pressing this key the first time will clear the entry register and displays the number "0". Pressing this key the second time will clear all registers. Clear Entry Key (CE) During a digital entry, pressing this key will clear the entry register and displays the number "0" Number, Decimal Key (“000”, “00”, “0 – 9”, “•”) The first number keyed in a sequence will clear the display and the pressed digit will be entered in the display. Successive entries will shift the display left and the keyed in data will be entered in the display register. The first decimal point entered is effective. An attempted entry of more than 12 digits or 11 decimal places will be ignored. 4• Product Specification (V1.0) 04.02.2010 (This specification is subject to change without further notice) EM34014A 10/12-Digit Calculator Battery/Solar/Dual Power Type Shift Key ( →) Deletes the right most digit and the other digits will shift to the right. Memory Plus Key (M+) Adds the current display to the memory contents. It will terminate a number entry. Memory Minus Key (M-) Subtracts the current display from the memory contents. It will terminate a number entry. Memory Recall Key (RM) Transfers the contents of the memory register into the display register. Memory Clear Key (CM) Clears the memory contents Memory Recall and Clear Key (RCM) First pressed of the RCM key, as the RM key, transfers the contents of the memory register into the display register. Second pressed of the RCM key, as CM key, clears the memory contents. Grand Total Plus Key (GT+) Adds the current display to the contents of the grand total memory. It will terminate a number entry Grand Total Minus Key (GT-) Subtracts the current display from the contents of the grand total memory.
