!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

POWER

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

UDisplays and prints the total and clears the total. Also resets

the item counter (

) to zero.

#Calculates the selling price and profit or loss amount on an

item.

0Displays and prints the value in memory and clears the

memory. Also clears

from the display and resets the

memory item count to zero.

;Displays and prints the subtotal in memory but does not clear

the memory.

FSubtracts the displayed value from memory. If a multiplication

or division operation is pending,

completes it and

subtracts the result from memory.

NAdds the displayed value to memory. If a multiplication or

division operation is pending,

completes it and adds the

result to memory.

Printing (POWER Switch)

OFF The calculator is turned off.

ON Calculations are displayed but not printed.

PRT 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.

Rounding (ROUND Switch)

PResults are rounded down (if DECIMAL = 1, 2.33 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).

QResults are rounded up (if DECIMAL = 1, 2.33 rounds to 2.4).

Using Decimals (DECIMAL Switch)

+Lets you add and subtract numbers without entering the decimal

point (key in 5321 to enter 53.21). Shows two decimal places.

FThe number of decimal places varies based on the result.

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

Entering a Tax Rate (TAX Switch)

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

CALC Stores the tax rate you enter for use in calculations.

Clearing Errors and Overflows

Correcting Entry Errors

If you have not pressed an operation key:

• To clear an incorrect entry, press I.

• 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 9, ., N,or F.

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 a row of dots and 0 .* and displays

Eand 0.

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

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

• Prints a row of dots and the first 12 digits of the result with the

decimal shifted 12 places to the left of its correct position.

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

places to the left of its correct position.

To clear an error or overflow, press 2. The memory is not cleared

unless the error or overflow occurred in a memory calculation.
