HOW TO A D D & S U B T R A C T with this THALES »KA« ==================================================================== Turning down the RIGHT WHEEL on front clears the ARITHMETIC UNIT. Turning the TOP WHEEL in the same direction clears the COUNTER UNIT. Pressing the big SILVER KEY clears the INPUT UNIT. The right LEVER ON TOP should be switched backward by default. The LEVER right beside the keyboard should be switched foreward to [+] by default. When an INPUT-KEY, ( eg. [7] ) is pressed, the whole column below [6] ... [1] switches too! Under the KEYBOARD this column forms a BAR with ( eg. 7 ) TEETH. Pressing the MAIN LEVER down, let the arithmetic unit SLIDE UNDER THE KEYBOARD to add the input value to the content of the arithmetic unit - On its END-POINT the COUNTER is adding 1 - Releasing the main lever let the arithmetic unit slide back to front and shows the actual content in its DISPLAY WINDOWS - The input unit will be cleared automaticaly. For REPEATED INPUT VALUES, the LEVER ON TOP has to be set to [R] - the keyboard will not be cleared after operation. For SUBTRACTION the LEVER RIGHT BESIDE THE KEYBOARD has to be set to [-] before the MAIN LEVER is pulled down. The main lever can also be mounted right.
