WHITE SPHERE Levers:
--------------------
Lower (shift right)  =  Doesn't print the calculated product
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.
