REPLACING THE RIBBON

Your calculator is shipped with a 2-color ribbon already in place. You do not need to install or change it before you begin using the calculator. When you have been using your calculator for some time, however, the print will gradually become faint, indicating that you should change the ribbon. To change the ribbon, follow these steps.

1.Remove paper roll, tearing paper at rear of calculator. Use the Paper Advance () key to feed the remaining paper tape through the printer. Then remove the printer cover.

2.Remove the old ribbon by pulling upward.

3.Install the ribbon spool with the black edge up. Roll from the outside of the full spool and place the first spool on the spindle not engaged by the lever. Thread the new ribbon along the outside of the guides and in front of the print wheels. Switch the lever to the other side and replace the second spool.

4.Rotate the spools to take up any slack. Replace the printer cover and the paper tape.

(Replace with Victor Ribbon #7010)

This section describes the mode switches, data entry keys, and operating keys provided on your calculator. The following terms are used in discussing your calculator’s operation:

The accumulator is the area of the calculator’s logic that stores a running total of the results of addition and subtraction operations. It is the “adding machine” portion of the calculator.

The calculating register is the area of the calculator’s logic where the intermediate and final results of multiplication, division and percentage calculations are stored. The contents of the calculating register do not affect the accumulator.

The keyboard register is the area of the calculators logic that stores the value that will immediately be used in the next calculation.

The item count register is the area of the calculator’s logic that counts your entries into the accumulator. Each positive entry is counted as one item. Each Negative entry is subtracted resulting in a net item count. It is also net or gross programmable.

The memory register is the area of the calculator’s logic that accumulates amounts you add to or subtract from the memory. Because the memory register is

-7 -

independent of the accumulator and the calculating register, it retains its value until you clear it with the Memory Total (MT) key.

SLIDE SWITCH FEATURES

This section illustrates and describes the mode switches you can use to control your calculator’s operation.

1. 5/4 Decimal Rounding Selector

This causes automatic round down (truncation).

5/4 This setting causes automatic round off. If the last digit of the result that will be printed or printed/displayed upon rounding is followed by a value of 0 to 4, the digit is unchanged. If the last digit of the result that will be printed or printed/displayed upon rounding is followed by a value of 5 to 9, the digit is rounded up.

This setting causes automatic round up

2. PRINT Printer Select Switch

(Non-print) Printer is activated only when feed key or non-add/date key is pressed.

PRINT Printer is activated as long as calculator is turned on.

3. + 0 1 2 3 4 6 F

Decimal Point Selector

+Monetary Add Mode: At this setting, amounts entered are assumed to be monetary. The calculator automatically supplies a decimal point to the left of the last two digits entered. Use this setting to add, subtract, multiply and divide decimals.

Units/price mode operation:

Multiplication: The first factor will be entered as a whole number and the second factor will have a decimal point supplied to the left of the last two digits.

Division: The first factor will have a decimal point supplied to the left of the last two digits and the second factor will be entered as a whole number.

0,1,2,3,4,6 Fixed decimal point mode; these settings specify the number of digits to the right of the decimal point that are shown in the result.

FFloating decimal point mode; this setting specifies that all digits of the result are shown, up to a maximum of 10 on model 1530-6, and 12 on model 1560-6 and 14 on model 1570-6. If the result exceeds these capacities, excess digits to the right of the decimal point are dropped. No rounding takes place.

When the Sigma switch is in the “∑” position, the results of multiplication or division calculations completed by the = or % key are automatically added to the accumulator.

When the Sigma switch is in this position, the results of these calculations are not added to the accumulator. The sum of these accumulations is displayed by depressing the Subtotal key and are displayed and cleared by depressing the Total key.
