3 Cancelling out of the setting mechanism

The setting mechanism and, with it, simultaneously
the check register can be cancelled out by pulling the
cancellation lever from back to front and then releas-
ing it again.

4 The product register

Now you will have to get to know the product re-
gister. This is located in the right-hand portion of the
carriage and has a capacity of 13 digits. The separate
digits are marked, as in the setting mechanism, by
means of small consecutively running figures from the
right to the left. The product register is cancelled out,
(i.e. brought back to zero) by pulling the left-hand
cancellation lever to the front and then releasing it
again.

5 The multiplier register with
   tens transmission

The purpose of the multiplier register is to count the
revolutions of the operating handle. it is located in
the left-hand portion of the carriage. As in all the
other mechanisms the 8 digits are marked by num-
bers; each of the markings indicates the position
of the carriage in this particular case. The multiplier
register of the 13 RM is also equipped with a re-
versing gear which enables optional counter-rotation.
The shift lever can occupy 3 positions: plus-neutral-
minus. Its basic position is at neutral and corres-
ponding to the first rotation of the operating handle
it is set to either ~+~ or ~---~. Once the lever is
in one of these positions it will remain there until
you return the counter to zero, when it will again
go to the central position. Normally, you need not
touch this reversing lever as it functions avtomatically,
but if you wish to chanae the direction of rotation
of the counter wheels, you may move it by hand;
alwavs remembering to see first of all that the handle
is in its neutral position. This reversing lever has
many uses, as by using this mechanism, both the
product and counter registers can react either posi-
tively or negatively simultaneously, or in opposite
di rections.

s Cancellation of the multiplier register

The multiplier register is cancelled out by means of
the right-hand cancellation lever. This is pulled to the
front and then re leased. The counter will then be
set to ~zero~ and the shift lever is again in ~neutral~.

7 CombSned cancellation

The cancellation levers for the product register and
for the multiplier register have been designed in
such a manner that they can be operated by a com-
bination grip with 2 fingers (best results are achieved
if forefinger and middle finger are used), thus pro-
ducing a combined cancellation. Thus, both registers
can be cancelled out with one movement only.

8 Step-by-step tabulating

Below the operating handle there is a shift rocker
arm, arranged as a double handle and by means of
which the carriage can be moved step-by-step into
the required calculating position. This rocker arm
enables the operation of the machine to be carried
out with one hand only.



9 Tabulating step-by-step
   or intermittently

The shift-key attached to the front of the machine
offers another possibility of moving the carriage to
the required calculating position. The shift-key can
be moved to the right or to the left. When doing so,
the carriage will always move one position in the
same direction.
