BASIC SETTINGS:
===============

(a) Crank:
----------
For addition (+) the crank is turned clockwise; for subtraction (-) the
crank is turned counter-clockwise. In the idle position the crank is DOWN
& LOCKED. To make one or more turns with the crank, pull out the handle to
unlock. When finished the turn(s), let the handle snap into lock again. The
locked down position only makes other functions (ex. clearing) accessible.

REMARK:      Every started turn has to be finished completely!
             Accidentally started turns are correctible somehow.

(b) Clearing Registers:
-----------------------
The input register
    can be cleared with the upper right lever by lifting it up
    (It is intended to use the thumb for). 

The arithmetic register & the counter unit
    will be cleared with the big lever on the right side of the carriage
    by lifting it up.

    Depending of the two little switches left of it, both registers can
    be cleared simultaniously (when both switches are down) or separate
    (when up = locked; left = counter, right = arithmetic unit).
    
(c) Shifting the Carriage:
--------------------------
With the 2-grip lever (located under the crank) the carriage is movable
one step right or one step left. With the front button the carriage can
be moved continuously when pressed down and right or left.

The left position "1" is the "Start Position" of the carriage.

(d) Counting Direction:
-----------------------
With the (+ <==> -) switch on the crank's holder it enables the counter
to work positive with (+) positive (clockwise) turns - and positive too
with (-) negative (counter-clockwise) turns of the crank.

ADDITION & SUBTRACTION:
=======================
Example:     123 + 45 - 6  =  162

Clear input, counter and arithmetic units; counter switch to (+)

ADD: Enter the first number (123) in the far right of the input unit.
Make a positive (clockwise) turn with the crank to transfer the number
into arithmetic unit. The counting unit displays the figure 1. Enter the
second number (45). Make a positive (clockwise) turn with the crank to
add the number. The arithmetic unit displays the intermediate sum (168)
and the counting unit displays the figure 2.

SUBTRACT: Enter the third number (6). Make a negative (counter-clockwise)
turn with the crank. The arithmetic unit displays the result (162) and
the counting unit is decreased by 1.

REMARK:      NEGATIVE RESULTS are displayed in the arithmetic unit
             as the COMPLEMENT of the next higher 10, 100, 1000, ...

             Example:   -12  =  99...9988

MULTIPLICATION:
===============
Example:     123 x 45  =  5535

Clear input, counter and arithmetic units; counter switch to (+)

Enter the multiplicand (123) in the far right of the input unit. The
multiplicator (45) has two digits, so the carriage is shifted to
position 2 by pressing the 2-grip lever forward.  Make positive
(clockwise) turns with the crank, until the first figure of the multi-
plicator (4) will appear in the 2nd position of the counter unit. Shift
the carriage to position 1 by pressing the 2-grip lever backward.
Repeat making positive turns with the crank, until the second figure
of the multiplicator (5) appears in the 1st position of the counter
unit. The multiplication is done: The multiplicand (123) stays in
the input unit, the multiplicator (45) in the counter and the result
(5535) is in the arithmetic unit.

DIVISION:
=========
Example:     22 : 7  =  3.1428571  Remainder 3

Division requires 3 steps:

(1st) To Set the Dividend into Arithmetic Unit:
-----------------------------------------------
    For the maximum number of decimals, pull out the carriage to the far
    right position. Enter the dividend (22) in the far right of the input
    unit. Make a positive (clockwise) turn with the crank to transfer
    into arithmetic unit.

(2nd) To Set the Divisor into Input Unit:
-----------------------------------------
    Clear counter & input units. Set counter switch to (-).
    Enter the divisor (7) above the dividend (22).

(3rd) To Divide:
----------------
    Make negative (counter-clockwise) turns with the crank until the
    arithmetic unit shows an "underflow". Make one positive (clockwise)
    turn with the crank. Move the carriage to the next left position.
    Repeat this procedure until the required number of decimals ...

    The result (3.1428571) is in the counter unit, and the remainder (3)
    is in the arithmetic unit. The divisor (7) stays in the input unit,
    therefore an additional decimal can be estimated...
    ( 4, cause 4 x 7 = 28).
