*****************************************************

ENTER A NUMBER:
---------------
The actual number of digits entered shows on the slot above the
keyboard. If wrong digits are entered, pull the left slider [C]
to clear the keyboard.

ADDITION:
---------
Pull the left-middle lever ( its window shows [+/-] ).
Everytime a number is entered and the [+] key is pressed, the
motor starts and the number is printed and added to memory.

REPEAT:
-------
To enter the same number more than once, pull the lever beside
[C] ( its window shows [R] ). The motor cycle starts, but the
keyboard will not be cleared.

SUBTRACTION:
------------
Enter the (negative) number into keyboard. Press the [-] key.
The motor starts and the number is printed and subtracted from
the memory.

SUBTOTAL:
---------
Set the right lever on bottom to [S]. The cumulated sum will be
printed when pressed [+].  The memory will hold the actual sum
after the motor cycle.

TOTAL:
------
Set the right lever on bottom to [T]. The cumulated sum will be
printed when pressed [+].  The memory will be cleared after the
motor cycle.

ID-NUMBERS:
-----------
An ID-Number can be entered and printed: Push the lever beside
[C] ( its window shows [N] = NonAdd ).  This input is not
registered in the arithmetic unit. 

MULTIPLICATION:
---------------
Push the left-middle lever ( its window shows [x] ).  Enter the
1st factor, press [+]. Enter the 2nd factor, press [+].  The
machine calculates the product, prints it and holds it in memory,
when the right-bottom lever is set to [S] - or, when [T], the
memory will be cleared after printing. If a multiplication loops,
PUSH THE RED KEY ON THE UPPER RIGHT UNTIL THE MACHINE STOPS.

BACK-TRANSFER:
--------------
When ( after a series of additions and subtractions ) the left-
middle lever is pushed to [x], in the window of the left-bottom
key apears [TT]. When this key is pressed, the actual memory will
be hold and can be used as a factor for multiplication.
( Example for "Chain Multiplications" see below ... )

CONSTANT MULTIPLICATIONS:
-------------------------
Pull the left-upper lever ( its window shows [C] ) and than push
the left-middle lever ( its window shows [x] ).  This makes the
1st factor to a constant ( see Example below ... ).

CHANGING THE PAPER ROLL:
************************
o  Open the top lid
o  Press the axle on both ends and lift the paper roll.
o  If necessary push the upper-right lever behind the rear paper
   slot to release and pull out the paper.
o  Put the axle into the new paper roll so that the paper end
   comes from bottom.
o  Push the upper-right lever to release the paper feeder and push
   the paper end into the rear slot until it can be seen in front.
o  Place the paper roll into holder by slightly pressing the axle
   on both ends.
o  Tighten the paper roll.
o  Turn the paper feeder more times until the paper is easy to grip.
o  Close the top lid and feed the paper through the window.

CHANGING THE RIBBON:
********************
o  Open the top lid
o  Observe how the ribbon is spooled !!!
 ( on  b o t h  spooles clockwise )  
o  Change the Ribbon
 ( the full spool on the right side )
o  Close the top lid

R E M A R K S :   How to get a NEW RIBBON for this old machine ???
==================================================================
There are cartridges for MATRIX-Printers on the market with 8 mm
NYLON-Ribbons. Check the cartridge before buying because there are
several available with different lengths.  In some cases you can
get 3 spools out of one cartridge!  You will get your fingers
dirty when you do the respooling - but the result is great!
And remember:  BOTH SIDES HAVE TO BE SPOOLED CLOCKWISE ...

PS.:   The  B E E R   M U G  is from   » BAYERISCHE STAATSBRAUEREI «
»  WEIHENSTEPHAN  ( since 1040 )  The Oldest Brewery in the World  «
