Clear the Arithmetic:
---------------------
(1st) Pull & hold the right (outside) crank;
(2nd) Pull the MAIN-LEVER; Release the (outside) crank.
( ATTENTION: The arithmetic will be cleared also after a ZERO INPUT !)
Enter & Add a Number:
---------------------
To enter a ( 7 DIGIT ) number, it is supposed, that the operator placed
his index finger on the figure desired and than placed the thumb on the
lever directly below. Then lift the thumb until it touches the index
finger. After enter all figures, pull the MAIN-LEVER to add the number
to the ( 8 DIGIT ) memory. Make sure to push back the MAIN-LEVER in full:
NOW (!) the 10s-CARRYs will be processed - and the input will be cleared.
Repeat a Number:
----------------
Enter the number. Pull the left lever (= REPEAT-LEVER ) until it locks.
Pull the MAIN-LEVER. In the round window left under the input-levers a
REPETITION-COUNTER get active ( 0 .. 9 ). Release the REPEAT-LEVER
b e f o r e the last input.
Subtraction:
------------
Only ADDITION is performed. For SUBTRACTION 9-Complement "Addition" has
to be used. ( For DETAILS see the INSTRUCTIONS to the BURROUGHS ... )

It reads: 10$/25ct .. 5$/10ct .. 2$/5ct .. 1$/1ct
What is the MEANING of it = ??? = Just DECORATION
G U E S S : May be it refers to making COIN-ROLLS to give to a bank ...
40 x Quarters (= 25 ct) = 10 USD
50 x Dimes (= 10 ct) = 5 USD
40 x Nickels (= 5 ct) = 2 USD
BUT: { 50 x Pennies (= 1 ct) = 50 ct } x2 = 1 USD ???
