Upper (= M ) Position: Hold Input as a CONSTANT ( Key [x] is blocked ! ) ENTER A NUMBER: --------------- The actual number of digits entered shows on the window above the keyboard. If wrong digits are entered, press the red key [C] to clear the keyboard. ADDITION & Subtraction: ----------------------- Everytime a number is entered and the keys [+] or [-] are pressed, the number is printed and added/subtracted to/from the memory. REPEAT: ------- When Press & Hold the [R]-Key, the [+] or [-] will use the last processed number as its input. NON-ADD: -------- Enter the item number and press the key [#]. This item number is printed, but it is not part of the addition/subtraction cycle. SUBTOTAL: --------- The cumulated sum will be printed when the key [◊] is pressed. The memory will hold the actual sum. TOTAL: ------ The total sum will be printed when the key [*] is pressed. The memory will be cleared. MULTIPLICATION: --------------- Enter the multiplicant and press [x]. Enter the multiplicator and press [=]. The product will be calculated and printed.
