Instruction manual

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 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. A F 0 2 3 4 Decimal Point Selector

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.
