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 calculator's 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.
•
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 (M*) key.

IDE SWITCH FEATURES
This section illustrates and describes the mode switches you can use to control your
calculator's operation.
1 01 2 3 6 F
Decimal Point Selector
0,1,2,3,6
Fixed decimal point mode; these settings specify the number of digits
to the right of the decimal point that are shown in the result.
Floating decimal point mode; this setting specifies that all digits of the
result be shown up to a maximum of 12 digits. If the result exceeds
these capacities, excess digits to the right of the decimal point are
dropped. No rounding takes place.

GT
Roundlnq Selector
Absolute round up
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.
Absolute round down (truncation).
Constant Calculation / Normal Calculation/ Add Mode
Switch
Constant Calculation
Normal Calculation. Non constant calculation & add mode selected.
Add Mode.
Use of the Add mode permits addition and subtraction of numbers
without an entry of the decimal point. Whe the add mode is activated,
the decimal point is automatically positioned according to the decimal
selector setting. It will be ineffective if decimal point is set to the F
position.
Grand Total Switch
Calculation without Grand Total
GT
Any total taken with [*] key is automatically accumulated to Grand
Total Memory. The accumulated grand total can be recalled by
pressing the [GT] key.
