Advances the paper. Clears the entire pending operation except the memory or the
grand total. Changes the sign (+ or –) 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. Pressed once, displays and prints the grand total of all totals.
Pressed twice, clears the grand total. This is active only if
PRINTER

Displays and prints the subtotal in memory but does not clear the memory.
F
Subtracts the displayed value from memory. If a multiplication or division operation is pending,
completes it and subtracts the
F
result from memory.
N
Adds the displayed value to memory. If a multiplication or division operation is pending,
completes it and adds the
N
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. Sets the number of decimal places to 0, 2, 3, 4, or 6.

Printing (PRINTER Switch)

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

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

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 10 places to the left of its correct position.
•
Prints
