Key Descriptions

Advances the paper.

Clears the entire pending operation except the memory or

the grand total.

Changes the sign (

–

) of the displayed number.

Interprets the number in the display as a percentage.

Clears an entry or an error or overflow.

Computes the percentage of change between two values.

(The price increase from 9.75 to 11.25 is 1.50, and the

percentage increase is 15.38%)

Calculates the selling price and profit or loss amount on an item.

(

Removes the last digit entered in the display.

Prints a reference number or date without affecting calculations.

Adds the stored tax rate to the value in the display.

Subtracts the stored tax rate from the value in the display.

Pressed once, displays and prints the grand total of all

totals. Pressed twice, clears the grand total. This is active

only if PRINTER = GT.

Displays and prints the total, but does not clear the total.

Displays and prints the total and clears the total. Also

resets the item counter (IC) to zero.

Displays and prints the value in memory and clears the

memory. Also clears Mfrom the display and resets the

memory item counter to zero.

;

Displays and prints the current total in memory but does

not clear the memory.

Subtracts the displayed value from memory. If a

multiplication or division operation is pending,

completes it and subtracts the result from memory.

Adds the displayed value to memory. If a multiplication or

division operation is pending,

completes it and adds

the result to memory.

Using Decimals (DECIMAL Switch)

Lets you add and subtract numbers without entering the

decimal point (key in 5321 to enter 53.21).

The number of decimal places varies based on the result.

0,2,3,4,6

Sets the number of decimal places to 0, 2, 3, 4, or 6.

Rounding (ROUND Switch)

Results are rounded down (if DECIMAL

= 1

, 2.39 rounds to 2.3).

5/4

Results are rounded up or down, depending on the value and

decimal setting (if DECIMAL =

, 2.349 rounds to 2.35).

Results are rounded up (if DECIMAL

= 1

, 2.33 rounds to 2.4).

Entering a Tax Rate (TAX Switch)

SET Lets you enter a tax rate to perform tax calculations.

CALC Stores the tax rate.

Printing (PRINTER Switch)

OFF Calculations are displayed but not printed.

ON Calculations are displayed and printed.

IC Both the printer and item counter are active. To clear the

item counter, press

GT Accumulates a running grand total of all calculations you

perform until you clear the grand total. To print a grand

total, press

. To clear the grand total, press

again.

Positive entries and results are printed in black; negative entries and

results are printed in red.

Clearing Errors and Overflows

Correcting Entry Errors

If you have not pressed an operation key:

•

To clear an incorrect entry, press

. You can then enter the

correct value and continue with your calculation.

•

To clear the last digit, press

(

If you have pressed an operation key:

•

To cancel an incorrect entry, press the opposite operation key. This

applies only to calculations involving

Error and Overflow Conditions and Indicators

If you divide by zero or calculate a selling price using a margin of 100%, an

error occurs. The calculator prints ERROR

0 .*

and displays Eand

An overflow occurs if you calculate a result with too many digits for the

calculator to display or print. When this occurs, the calculator:

•

Displays Eand the first 12 digits of the result with a decimal point 11

places to the left of its correct position.

•

Prints ERROR and the first 12 digits of the result with the decimal

shifted 11 places to the left of its correct position.

To clear an error or overflow,

press

. The memory is not cleared

unless the error or overflow occurred in a memory calculation.
