If wrong digits are entered, pull the left slider [C] to clear the keyboard. ADDITION: --------- Set the left lever so, that 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: --------------- Set the left lever so, that 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 ROUND KEY ON THE UPPER RIGHT TO STOP THE MACHINE. DIVISION: --------- Set the left-middle lever that its window shows [:]. Enter the divident, press [+]. Enter the divisor, press [+]. The machine calculates, print quotient & reminder and clears the memory. If a division loops, PUSH THE ROUND KEY ON THE UPPER RIGHT UNTIL THE MACHINE STOPS. 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 ( automatic reverse spooling ! ) o Close the top lid PRINTOUT - Example with Comments: *************************************** ^^^^^^^^^^^^^^^^^^^^^^ To clear memory: | .00 T | Set [T=Total], Press [+] | | Set [S=Subtotal] | | < Max.Input = 10 decimals > | 98,765,432.10 | Enter (1st) number, Press [+] | 87,654,321.09 | Enter (2nd) number, Press [+] | 186,419,753.19 S | Press [+] to print cumulated sum | | | 1.23 - | Enter (neg.)number, Press [-] | 186,419,751.96 S | Press [+] to print cumulated sum | | | 4.56 | Enter number, Pull & Hold [R] | 4.56 | Release [R], Set [T=Total] | 186,419,761.08 T | Press [+] to print total sum | | < Max.Output = 11 decimals > | | | .00 T | Press [+], Memory is clear | | | .47 N | Enter ID #47, Push [N=NonAdd] | 6,789.00 | Enter value, Press [+] | .11 N | Enter ID #11, Push [N] | 5,432.00 | Enter value, Press [+] | 12,221.00 T | Press [+] to print total sum of values | | | .00 T | Memory is clear | | | .12 | Enter number | .24 - | Enter (larger negative) number | .12 T C | Negative sum = C = Credit | | | .00 T C | Memory is clear | | | | EXAMPLE 12 x 12 = 144 | | Set [X = Multiplication] |x .12 | Enter 1st Factor, Press [+] |x .12 | Enter 2nd Factor, Press [+] |x .00 | Machine calculates |x 1.44 T | Print Product (and clears memory) | | | .00 T | Memory is clear | | | | EXAMPLE (14 x 13) - (12 x 11) = 50 | | Set [X=Multiplication] | | Set [S=Subtotal] |x .14 | Enter 1st Multiplicant, Press [+] |x .13 | Enter 2nd Multiplicant, Press [+] |x .00 | Machine calculates and |x 1.82 S | 1st Product printed | | Set [T=Total] |x .12 | Enter 3rd Multiplicant, Press [-] |x .11 | Enter 4th Multiplicant, Press [-] |x .00 | Machine calculated 2nd Product and |x .50 T | Print Result (and clears memory) | | | .00 T | Memory is clear | | | | EXAMPLE 22 : 7 = 3.14285714 | | Set [: = Divisionion] |: 22,000,000.00 | Enter Divident, Press [+] |: .07 | Enter Divisor, Press [+] |: 3,142,857.14 | Machine print Quotient and |: .01 T | Print Remainder (and clears memory) | | | .00 T | Memory is clear | | ^^^^^^^^^^^^^^^^^^^^^^ R E M A R K S T O R E S T O R A T I O N : ==================================================================== This VICTOR AUTOMATIC was found "New-In-The-(Oben)Box" ( together w. power cable, instruction booklet & plastic cover ) in an old office supply store in Southern Oregon / USA. Addition & subtraction was working, but multiplication & division was not. After applying WD-40 & appropriate TEST DATA, the clogged gears were freed and the VICTOR calculator was working ( see above ). After 3 days of TESTS the machine fall into ENDLESS PRINTING ZEROS like the VICTOR AUTOMATIC-75 and there seems no way to find out why. After hours of carefully inspecting the mechanics, a CLAMPED LEVER on the left inside was discovered and freed. More TESTS showed sometimes the first entered figure was dropped ??? After disassembling: The input unit was ok, but the MATRIX was not ! The FRONT-LEFT PIN fell randomly down, blocked sensing the entered figure-pin. Knowing the difficulties involved in REPAIRING A MATRIX (s. VICTOR TALLYMASTER ) As a SOLUTION this ZERO-Pin was REMOVED ... !!! BUT ATTENTION - Only possible in this LEFTMOST POSITION !!! !!! ASSUMING THAT NO LEADING ZERO IS ENTERED WITH THE NUMBER. !!! !!! ( Because a NON-SET matrix-column is recogniced as a "9". ) !!! More T E S T S with SOMETIMES WRONG RESULTS raised the QUESTION: " Was this VICTOR-AUTOMATIC-73 a RETURNED LEMON ??? " Autumn 2014 ... An "ORGAN-TRANSPLANT" made: The Error-Matrix was e x c h a n g e d AGAINST THE MATRIX OUT OF THE VICTOR AUTOMATIC-75. It took hours ... Going through LOOPING ZEROS again ... ... A CHAOTIC HARDWARE! Winter 2015 ... ... Looking for new errors, a BENT STUD (= Part of the input unit) was detected. In trying to straiten it broke. To avoid disassembling (= May facing new problems) a BRASS PIECE was made and fixed with 2-Component-Glue ... WHAT NEXT ??? ... BE PREPARED !!!
