WHITE SPHERE LEVERS:
--------------------
(*) Lower (shift right) = Doesn't print the calculated product
& Hold memory for combined multiplication
( see example: 11x11 - 9x9 = 40 )
(M) Upper (shift up) = SAVE LAST NUMBER or SUM as a CONSTANT
(Blocks the left Function-Keys)
RECALL CONSTANT = Shift down & press [+] or [-] key
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:
-------
No "REPEAT"-Key is neccessary: The last number is held in memory
and can be re-used by pressing the [+] or [-] key again.
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.
( Examples for "Chain Multiplications" see below ... )
OVERFLOW MARKER:
----------------
When a product exceeds 12 digits, the WRONG RESULT is printed
with 3 points on its left side.
DIVISION:
---------
Enter the divident and press [:]. Enter the divisor and
press [:=]. The quotient will be calculated and printed.
CHANGING THE PAPER ROLL:
************************
Pull the holder clips on both ends and lift the paper roll.
CHANGING THE RIBBON:
