*****************************************************
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 «
