OPERATIONAL NOTES To insure trouble-free operation of your SHARP calculator, we recommend the following:

1. The calculator should be kept in areas free from extreme temperature changes, moisture, and dust. 2. A soft, dry cloth should be used to clean the calculator. Do not use solvents or a wet cloth. 3. Since this product is not waterproof, do not use it or store it where fluids, for example water, can splash onto it. Raindrops, water spray, juice, coffee, steam, perspiration, etc. will also cause malfunction. 4. If service should be required, use only a SHARP servicing dealer, a SHARP approved service facility or SHARP repair service. 5. If you pull out the power cord to cut electricity completely, the presently stored exchange rate will be cleared.

00.11.7, 2:15 PM POWER SWITCH; PRINT / ITEM COUNT MODE SELECTOR:

“OFF”: “•”: “P”: “P•IC”:

Power OFF Power ON. Set to the non-print mode.

Power ON. Set to the print mode. Power ON. Set to the print and item count mode. For addition or subtraction, each time + is pressed, 1 is added to the item counter, and each time – is pressed, 1 is subtracted. • The count is printed when the calculated result is obtained.

, C CE C CE clears the counter.

• Pressing of * The built-in LCD backlight turns on when the calculator’s power is on and turns off when the power is off. Note: The counter has a maximum capacity of 3 digits (up to ±999). If the count exceeds the maximum, the counter will recount from zero. F

A DECIMAL / ADD MODE SELECTOR:

“3, 2, 1, 0”: Presets the number of decimal places in the answer. “F”: The answer is displayed in the floating decimal system. “A”: The decimal point in addition and subtraction entries is automatically positioned to the 2nd digit from the lowest digit of entry number. Use of the add mode permits addition and subtraction of numbers without entry of the decimal point. Use of , and will automatically override the add mode and decimally correct answers will be printed.

The decimal point floats during successive calculation by the use of or

. If the decimal selector is set to “F” then the answer is always rounded down ( ). 2

This selector will accumulate the following:

(“ + “ will be printed.) . 1. Addition and subtraction totals obtained with 2. Product and quotient totals obtained with + or – . 3. Answers obtained with % or MU . Neutral

Prints and clears the “GT” memory contents.

NON-ADD / SUBTOTAL KEY:

Non-add — When this key is pressed right after an entry of a number in the Print mode, the entry is printed on the left-hand side with “#”. This key is used to print out numbers not subjects to calculation such as code, date, etc Subtotal — Used to get subtotal(s) of additions and/or subtractions. When pressed following + or – , the subtotal is printed with “ ” and the calculation may be continued.

C CE CLEAR / CLEAR ENTRY KEY:

This key also serves as a clear key for the calculation register and resets an error condition.

Clear entry — When pressed after a number and before a function, clear the number. TOTAL KEY: When pressed after + or – , prints the total of addition and subtraction with “∗”. EQUAL KEY: Gives the results of multiplication and division and performs repeat calculation with a constant. Multiplication: The calculator will automatically remember the first number entered (the multiplicand) and instruction. Division: The calculator will automatically remember the second number entered (the divisor) and instruction. 3

Changes the algebraic sign of a number (i.e., positive to negative or negative to positive).

Used to perform mark-ups, percent change and automatic add-on/discount.

M RECALL AND CLEAR MEMORY KEY M STORE KEY:

This key is used to store an exchange rate. • A maximum of 6 digits can be stored (decimal point is not counted as a digit). • Only one rate can be stored. If you enter a new rate, the previous rate will be cleared. CONVERSION KEY (TO A NATIONAL CURRENCY) CONVERSION KEY (TO THE EURO CURRENCY)

Appears when a number is in the memory.

Appears when a number is negative.

Appears when an overflow or other error is detected.

Grand total memory symbol

Appears when a number is in the grand total memory.

National Currency symbol

Appears when an entered value is converted to present national currency. This symbol also appears when an exchange rate is stored.

Euro Currency symbol

Appears when an entered value is converted to Euro currency. This symbol also appears when an exchange rate is stored.

00.11.7, 2:15 PM PAPER ROLL REPLACEMENT Never insert paper roll if torn. Doing so will cause paper to jam. Always cut leading edge with scissors first.

1) Insert the leading edge of the paper roll into the opening. (Fig.1) 2) Turn the power on and feed the paper by pressing

3) Lift the attached metal paper holder up and insert the paper roll to the paper holder.

DO NOT PULL PAPER BACKWARDS AS THIS MAY CAUSE DAMAGE TO PRINTING MECHANISM.

INK ROLLER REPLACEMENT If printing is blurry even when the ink roller is in the proper position, replace the roller.

Ink roller: Type EA-781R-BK (Black) Type EA-781R-RD (Red) WARNING APPLYING INK TO WORN INK ROLLER OR USE OF UNAPPROVED INK ROLLER MAY CAUSE SERIOUS DAMAGE TO PRINTER. 1) 2) 3) 4)

Set the power switch to OFF.

Remove the printer cover. (Fig. 1) Remove the ink roller by turning it counterclockwise and pulling it upward. (Fig. 2) Install the correct color new ink roller and press it in the correct position. Make sure that the ink roller is securely in place. (Fig. 3) 5) Put back the printer cover. 5

00.11.7, 2:15 PM Red

Cleaning the printing mechanism

If the print becomes dull after long time usage, clean the printing wheel according to the following procedures: 1) Remove the printer cover and the ink roller. 2) Install the paper roll and feed it until it comes out of the front of the printing mechanism. 3) Put a small brush (like a tooth brush) lightly to the printing wheel and clean it by pressing . 4) Put back the ink roller and the printer cover. Notes: • Do not rotate the printing mechanism manually, this may damage the printer. • Never attempt to turn the printing belt or restrict its movement while printing. This may cause incorrect printing.

ERRORS There are several situations which will cause an overflow or an error condition. When this occurs, “E” will be displayed. The contents of the memory at the time of the error are retained.

If “0 • E” is displayed at the time of the error, “– – – – – – –” will be printed in red and C CE must be used to clear the calculator. Error conditions: 1. When the integer portion of an answer exceeds 12 digits. 2. When the integer portion of the contents of the memory exceeds 12 digits. (Ex. M 999999999999 M+ 1 M+ ) 3. When any number is divided by zero. (Ex. 5 0 ).
