3.Remove any packing materials from the printer compartment.

4.Replace the printer compartment cover.

5.Plug the calculator into an electrical outlet.

6.Set the power switch on the right side of the calculator to on (P).

7.Place the paper roll on the paper holder.

8.Insert the end of the paper into the paper slot on the back of the calculator as shown. To avoid paper jams, use quality bond paper.

9. While feeding the paper into the slot, press and hold &.

Note To prevent damaging the printer (which may void the warranty), move the PRINTER switch to OFF when operating the calculator without paper.

Key Descriptions

&Advances the paper.

2Clears the entire pending operation except the memory or the grand total.

OChanges the sign (+ or – ) of the displayed number.

>	Interprets the number in the display as a percentage.

IClears 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.

4	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.

EDisplays and prints the total and clears the total. Also resets the item counter (IC) to zero.

0Displays and prints the value in memory and clears the memory. Also clears M from the display and resets the memory item counter to zero.

2

;Displays and prints the current total in memory but does not clear the memory.

FSubtracts the displayed value from memory. If a multiplication or division operation is pending, F completes it and subtracts the result from memory.

NAdds the displayed value to memory. If a multiplication or division operation is pending, N 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).

F	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, 2.349 rounds to 2.35).

9Results 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 E or 0.
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 I. 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 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 ERROR 0 .* and displays E and 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:

•Displays E and 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 2. The memory is not cleared unless the error or overflow occurred in a memory calculation.
