CLEAR THE ARITHMETIC UNIT:
--------------------------
Make sure the left vertical lever on front is set to (+) ADDITION.
If not, push it to the right to release the lock and move it from
(-) to (+). Pull down the lever on the right side for clearing.

ENTER A NUMBER:
---------------
Use a pen and pull-down the appropriate number. Depending of the
left vertical lever on front, the input is (+) ADDED or (-)
SUBTRACTED. The result is visible in the arithmetic unit.

INPUT CHECK:
------------
When the lever on the right side is set counter-clockwise, the input
will stay and show the number entered in the lower display. Before
entering a new number, press the bar on front to release the input
segments. If the lever is set clockwise, the release bar on front is
locked down and each input segment snaps back immediately.

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

Example:   -12  =  9...988

REMARK: "1261" = Dec.1961 = PRODUCTION-Code is scratched in the bottom
