  ===>>>  Have a look at the "MONROmatic" Manual !  <<<===

The lower knob (2), which controls the lower dials, has three
positions: When all the way in, the lower dials can be cleared
and when pulled all the way out the lower dials are locked against
clearance. When the knob is in the third or half-way position, the
lower dials are split into two sections so that those on the right
are locked against clearance while the dials on the left can be
cleared. The upper knob (1) has only two positions and controls
the upper dials accordingly.


REMARK to the 10s-Carry of the Arithmetic Unit in the CSA-10:
-------------------------------------------------------------
Because 10s-carry is processed together with the body underneath,
there is NO 10s-CARRY left of position 13 when the carriage is in
its leftmost position!
